6 PROTECTION AGAINST WATER IS A MUST The causes and types of water damage to buildings Water and waterborne salts cause the most building damage. Saturated masonry threatens the very fabric of a building and the health of its occupants. Hazards such as mould and fungal growth can also develop in wet and damp conditions. There are also substantial energy losses through wet and saturated areas of a building envelope. Where people live and work, the walls and basement areas must be dry and waterproof. Defective, damaged or deteriorated building components or elements, such as leaking joints or roofs, can all allow water penetration which can then lead to one or more of the problems listed on the opposite page. 6

7 1 RAIN AND RUN OFF WATER 2 HYGROSCOPIC MOISTURE 3 CONDENSATION Water penetrates the masonry where the waterproofing is missing or defective. Salts in the fabric of the wall have the capacity to absorb moisture from the atmosphere and the environment (hygroscopic salts) and absorb it into the wall. Water vapour condenses forming water on the cold surfaces caused by thermal bridges in the wall. Harmful salts 4 MOISTURE PENETRATION FROM OUTSIDE Moisture penetrates the masonry and/or the floor slabs if the exterior waterproofing is missing or defective. Salts and their typical sources Sulphates, e.g. dissolve in the moisture through contact with gypsum plaster Chlorides, e.g. penetrate in the water from de-icing salts exposure/splashes etc Nitrates, e.g. dissolve in the moisture from urea de-icing solutions or from leaking drains 5 RISING DAMP Moisture penetrates the masonry through a defective or missing horizontal damproof course and/or the exterior waterproofing. It then rises through the masonry by capillary action. The resultant salt damage can include: Mechanical damage due to crystallisation and hydration Mechanical damage due to frost/freeze thaw action Further increases in the moisture content of the masonry and floor slabs As water and moisture penetrates the masonry, salts can also penetrate (i.e. Chlorides) or dissolve in the penetrating moisture (i.e. sulphates) and then form more damaging salts in the masonry, particularly at the points where the water evaporates. In saturated masonry these salts are carried though into the external face of the walls with the water. The water then evaporates from the surface, but the salts remain in the masonry. This continuous cycle can greatly increase the salt concentrations and thus in turn the hygroscopic action (the rate of water absorption from the environment): a vicious spiral. 7

8 CORRECT DIAGNOSIS FIRST Building condition survey and analysis In a professional condition survey, all of the damage to the building must be examined in detail, evaluated and measured. It is very important to include a moisture and harmful salts assessment and to evaluate the specific conditions of exposure with actual and potential points of water ingress. After collating the results of all of these analyses, sustainable and economic refurbishment specifications can be developed. The decision can also be made on whether horizontal or vertical waterproofing is necessary, whether vertical waterproofing should or can be installed internally or externally and what methods can be used for any additional horizontal waterproofing or other project specific details and requirements. Where necessary, waterproofing must also comply with the latest Building Regulations for thermal insulation and to prevent Condensation within the masonry fabric of the structure. Correct diagnosis first Definitive results require appropriate sampling. The sample quantity and type to be taken obviously depends on the objectives and test methods. The number of samples must allow for the various types of damage, materials and building components involved. The samples size and quantity must be large enough to fully represent the size and nature of the structure, plus the full cross section and composition of masonry and other areas of the building envelope. Analytical results from undersized samples or insufficient quantities of samples can often be misleading and differ considerably from the real typical characteristics. For assistance in precisely defining the correct requirements for your structure please contact Remmers Technical Service Department. Typical sample sizes Core Ø 5 cm, length 12 cm (without centre hole): To determine strength properties Core Ø > 3cm, length 5cm (without centre hole): To analyse the microstructure and detemine the moisture and salt contents Sample as many aspects and elevations as possible Individual samples are generally analysed to determine the moisture and salt content of a building section or component with as many samples taken as agreed to be necessary, according to the visible assessment and extent of any damage. The samples are taken at different heights and depths the sampling method, the date and the weather conditions are all recorded, as is the location of each sampling point. Note: It is important that the sample materials characteristics must not be changed by its packaging, transport or storage (e.g. special attention must be paid to conservation of the moisture content by vapour tight sealing). Taking cores to determine moisture and salt contents 8

9 Moisture content The moisture content of the sampled materials can be determined by two methods: Darr s method The samples are dried in a drying cabinet at 105 C until they a constant weight. The moisture content is then calculated mathematically. CM (calcium carbide) method The sample is prepared and mixed with calcium carbide and a quantity of acetylene gas (C 2 H 2 ) equivalent to the moisture content is released and measured according to a table. Determining the root causes of damage Test methods do not reveal the source or the root cause(s) of the moisture or the penetration level. Further data and references are needed for this, including determination of Maximum capillary water absorption Maximum water absorption (saturation moisture content) Hygroscopic moisture absorption Condensation formation Microscopic examination of a material sample Maximum capillary water absorption The maximum capillary water absorption is an important characteristic. It is the maximum quantity of water, which a dried material sample can absorb through capillary action due to its dried voids content and voids geometry. Maximum water absorption (saturation moisture content) To determine the maximum water absorption, the full dried void content of the sample is filled with water under pressure. Hygroscopic moisture absorption Moisture penetration levels do not provide reliable results on the causes of moisture penetration. It is not easy to detect whether the moisture has migrated by capillary action from the liquid phase or whether it has also been absorbed hygroscopically from the atmosphere or at least partially. Confirmation of this is only possible by the so called exclusion method: The hygroscopic moisture absorption is measured at one or more points by exposing dried material samples to a specific relative humidity at a constant temperature in a climate chamber for a given length of time. The hygroscopic moisture absorption value is then obtained from the weight increase observed. 9

10 In Germany waterproofing with polymer modified, high-build bitumen coatings (known as KMB) is covered by the German Standard DIN in Parts 4, 5 and 6 Based on tried and tested materials and approaches, but not yet standardised describes the content of German WTA data sheet Waterproofing of building components in contact with the ground SUCCESS THROUGH MEETING AND EXCEEDING STANDARDS BS 8102 plus German Standard DIN and the WTA Directives Note: In the UK the Building Regulations require foundations and below ground structures to be waterproofed, but they do not stipulate how this is to be achieved. British Standard BS 8102, is actually a Code of Practise referring to the requirements for waterproofing below ground basements and other structures. German Standard DIN 18195, Part 1, section 4.1 The performance and the durability of waterproofing naturally depend on its correct design and installation, but also on functional design and construction of the building and the components on which the waterproofing is applied. German Standard DIN is therefore directed at both the specialist waterproofing contractor and those responsible for the overall design and construction of the building. Every designer is required to exercise the greatest care in the design of the waterproofing and to use reliable and proven approaches. WTA Directives: The design of the waterproofing approach and system The WTA (German Technical Committee for Building Conservation and Heritage Preservation) promotes building conservation in dialogue with all of the professional parties and responsible organisations involved. Remmers are a permanent member of this well established and respected technical committee. Not all of the waterproofing systems proven in the field are yet covered by the DIN standard. Clear information on the correct procedure from condition survey to specification and materials selection, through to the waterproofing systems installation procedure, are given in the WTA Directive waterproofing of building components in contact with the ground. 10

11 The KMB (polymer modified bitumen) Directive The directive for the design and installation of waterproofing of building components in contact with soil, using polymer modified, high-build bitumen coatings (KMB), also describes their detailed installation procedure. This is in a clear and understandable way for the both the designer and the contractor, thereby providing an effective code of practice which supplements the standard DIN The WTA directive for KMB and the directive for flexible waterproof sealing coats are practical guides to these waterproofing systems for designers and contractors Well and truly proven: The waterproofing products in the Remmers Kiesol system Remmers waterproofing with polymer modified, high-build bitumen coatings (KMB) in the Kiesol system were and still are, well ahead of the standard. Based on many years practical experience in the right applications the undisputed advantages of these slurry sealing coating seals are already fully utilised by Remmers. With the Remmers systems as described on the following pages, designers and contractors select reliable waterproofing technologies, which have been proven over and over again. This is also ensured for our customers, by the Remmers System Guarantee (RSG, see P. 51). Extensive independent test reports, certificates, assessments, product reviews, expert analyses, patents and our external monitoring to DIN, European and ISO regulations, all confirm the high quality and reliable performance of both the individual Remmers products and when they are combined together as the systems.

12 DEPENDENT ON THE WATER INGRESS AND EXPOSURE POTENTIAL The Specific Waterproofing Requirements Selection of the right waterproofing system depends on the type of water ingress and exposure anticipated. Durable, functional waterproofing can only be achieved by correct classification of this exposure. DIN divides water exposure into the following four conditions in its Parts 4-6: In contact with ground water (Part 4) Ground water is the water which is capillary bound in the soil. It can also move against gravity by capillary forces. Ground water is always present in the soil to some degree and represents the minimum level of waterproofing exposure. This minimal load condition can only be assumed if the site consists of non-compacted soil down to a sufficient depth below the base of the foundation, and this also applies to the backfill: for example, sand or gravel with a minimum hydraulic conductivity (K) of K > 10-4 m/s. Surface and storm water can then seep down into the open water table without exerting hydrostatic pressure on the waterproofing. Infiltrating water not under pressure (Part 4) Infiltrating water not under pressure places the same stress on the waterproofing as the ground water exposure load condition outlined above. To withstand this exposure long term, a drainage system conforming to DIN 4095 must be installed in or around the external walls and floors. This should usually consist of a ring drainage system, installed in conjunction with building regulations and the drainage system for the roof and walls, this will then also act as protection for the external waterproofing system. 12

13 Infiltrating water intermittently under pressure (Part 6) Intermittent infiltrating water under pressure creates hydrostatic pressure on the waterproofing system. The water cannot percolate quickly enough down to the water table i.e. through dense or compacted soil; therefore it builds up with increasing pressure from below. The maximum foundation depth for this classification is 3 m below the ground level. The designed permanent ground water level for this classification must be at least 300 mm below the bottom of the floor slab. This should be determined from the regional and site records over many years and as close to the actual site as possible. Water under external hydrostatic pressure (Part 6) External water pressure represents the same exposure load on the waterproofing system as intermittently infiltrating water under pressure. The difference is that the normal water level is expected to be less than 300 mm below the bottom of the floor slab. As polymer modified bitumen systems (KMB) are not yet approved for this exposure condition in DIN 18195, in Germany for their use a building regulations variation agreement under VOB Part C is necessary. However polymer modified bitumen systems (KMB) have actually already been used successfully for this exposure classification for many years. 13

14 14 External waterproofing for ground water contact durable protection

15 TIME PROVEN TO BE WATERPROOF FOR MANY YEARS External waterproofing for ground water contact Remmers Kiesol systems have become synonymous with durable waterproofing. They have proved themselves over many years for all load and exposure conditions and all types of structures. The Remmers systems provide a reliable solution for every substrate. The mortar levelling systems and slurry coats for masonry substrates are highly sulphate resistant. Additionally the bitumen based bond coats and high polymer content slurry systems, have proved highly effective for many years in refurbishing and re-waterproofing old bituminous substrates. All Remmers slurry, levelling and high-build coating systems use state of the art material technology. They are extremely easy to apply, manually or by machine. They are reliable and very economic in use. Many impressive references and numerous test certificates and waterproofing system inspection reports confirm the strengths of the Remmers solutions: Usable on damp substrates Extremely high pressure resistance of the polymer modified bitumens Reinforcing is not necessary for any exposure condition Rapid drying and curing Economic with high solids contents (approx. 90 %) Ecological: solvent free and environmentally safe Resistant to corrosive substances (conform to DIN 4030) Maximum security due to excellent substrate and intercoat adhesion WHEN THINGS LOOK BLACK, INSIST ON REMMERS FOR CLARITY When a leaking basement is exposed, an old black coating is often revealed. What is it? Tar or bitumen? This must be determined by testing. This is because durable refurbishment is only possible on bituminous substrates. Only limited adhesion can be obtained on tar based materials never durable waterproofing! A quick on the spot test: It is easy to establish whether a material contains tar or bitumen with petroleum spirit: If the material easily dissolves, it is bitumen If the material is resistant or only slightly dissolves, then it is tar For your additional security: You can send a sample to our laboratories for confirmation testing. Therefore: Tar must be removed sound bitumen can usually remain. 15

16 NEW FROM TOP TO BOTTOM External waterproofing for ground water contact masonry substrates If there is no existing waterproofing, the substrate only requires cleaning. Surface defects of 5 to 50 mm are levelled and sealed with the Kiesol mortar and sealant system in one operation. There are standard and quick setting versions, both highly refined and shrinkage compensated for total crack resistance. Small and large areas can be waterproofed very economically manually or by machine, which makes it even faster. Two additional factors must also be taken into account for the thermal insulation of a basement: Firstly, the Minimum thermal insulation required by the German building regulations (LBO) must always be achieved. These requirements are given in the Technical Construction Regulation (TBB) DIN Secondly, the energy-saving thermal insulation specified in the Energy Saving Directive (EnEV) must be met. Condensation protection to DIN must also be provided. 16

17 THE SEQUENCE OF OPERATIONS How this waterproofing system is achieved 1 PREPARATION AND CLEANING Any edges or corners on the foundations are chamfered so that there are no sharp arrises. The surfaces are cleaned and any loose or friable particles or other contaminants are removed, by using a grinding machine or Rotec technique. 2 PRIMING WITH KIESOL The Kiesol primer is applied uniformly by spray. Highly absorbent substrates are predampened to reduce suction. 3 BOND COAT WITH SULFATEX GROUT Within the Kiesol open time, the bond coat of Sulfatex Grout is applied by brush. 4 LEVELLING WITH WATERPROOFING FILLER All rough areas and surface defects are filled and levelled with Waterproofing Filler, wet on wet. 5 FORMING A SEALING FILLET WITH WATERPROOFING FILLER A corner sealing fillet is also formed with Waterproofing Filler wet on wet, using a special coving trowel. 6 APPLYING THE 1ST WATERPROOFING LAYER WITH PROFI TIGHT The 1st waterproofing layer of Remmers polymer modified bitumen is applied by brush trowel or spray. 7 APPLYING THE 2ND WATERPROOFING LAYER As soon as the 1st layer has dried, the 2nd layer of Profi Tight can be applied (Coverage, layer thickness etc. are dependent on the anticipated exposure conditions and must be detailed in the specifications of the project). 8 FIXING THE PROTECTION SYSTEM CLIPS The clips are fixed into the substrate waterproofing with screws above the ground level. 9 PROTECTING THE CURED WATERPROOFING SYSTEM When the waterproofing system has completely dried (confirmed by the control samples), it must be protected with Remmers protection system prior to back filling. 17

18 FROM OLD TO NEW The Refurbishment of External Bituminous Waterproofing in ground contact It is always essential to check whether existing bituminous coatings are sound and have a good bond to the substrate, before commencing the waterproofing works. Any loose or friable particles, flaking areas or other contaminants must be removed. If in doubt as to the existing materials condition, always decide on its removal. Sound bitumen waterproofing materials are prepared for refurbishment with a new coating, by cleaning with high pressure water jetting. The highest exposure stresses will occur at the base and the old waterproofing should always be completely removed here in every case, back to the sound masonry substrate. 18

19 THE SEQUENCE OF OPERATIONS How this type of waterproofing system is achieved 1 PREPARATION: REMOVING THE OLD COATING In the highly stressed area at the bottom, the old waterproofing is completely removed back to the sound masonry substrate. 2 CLEANING THE FOUNDATIONS Any edges or corners of the foundations are chamfered so that there are no sharp arrises. Any loose or friable particles or other contaminants are removed ie by high pressure water jetting. 3 PRIMING WITH KIESOL The Kiesol primer is applied uniformly by spray. Highly absorbent substrates are pre-dampened to reduce suction. 4 BOND COAT OF SULFATEX GROUT Within the Kiesol open time, the Sulfatex Grout bond coat is applied by brush. 5 LEVELLING WITH WATERPROOFING FILLER All spalling and surface defects up to 50 mm deep are filled and levelled with the filler by trowel in one operation. 6 FORMING A SEALING COVE WITH THE WATERPROOFING FILLER A corner sealing cove is also formed with the filler by trowel wet on wet, using a special coving trowel. 7 APPLYING THE ELASTOGROUT 1 K The elastic Elastogrout 1K is applied in a thin layer uniformly over the whole surface by trowel. 8 APPLYING THE BITUMEN WATERPROOF COATING WITH PROFI TIGHT After the bond coat has set, the Polymer Modified waterproof coating is applied in two coats (Profi Tight). 9 PROTECTING THE CURED WATERPROOFING SYSTEM When the waterproofing system has completely dried (confirmed by the control samples), it must be protected with Remmers Protective Sheeting System prior to back filling. 19

20 DOUBLE SECURITY FOR THE FOUNDATION TO WALL JUNCTIONS External waterproofing ground contact Foundation/Wall junctions The Remmers waterproofing system for the foundation to wall junctions can be flexible or mineral depending on the requirements. The options are highly refined, bitumen waterproofing with 1 or 2 component versions in rapid or normal setting grades. All are highly sulphate resistant. Tested solutions with Remmers waterproof renders give reliable protection, even in the splash zones. The ground contact foundation waterproofing must overlap the wall waterproofing by 20 cm minimum. This is also tested because a good bond in these overlapped areas also prevents any possible under seepage or water penetration. 20

21 THE SEQUENCE OF OPERATIONS From the waterproofing to the rendering 1 PRIMING WITH KIESOL Kiesol is applied to at least 30 cm above ground level and to at least 20 cm below ground level by spray. 2 BOND COAT WITH SULFATEX GROUT Within the Kiesol open time, the bond coat of Sulfatex Grout is applied by brush. 3 LEVELLING WITH WATERPROOFING FILLER All rough areas and surface defects are levelled with the Waterproofing Filler wet on wet. 4 WATERPROOFING WITH SULFATEX GROUT The waterproofing is achieved by applying at least two coats of Sulfatex Grout by brush. 5 SPRITZ BOND COAT WITH PREPARATORY MORTAR The Remmers spritz bond coat is sprayed into the final wet slurry coat covering it completely. 6 APPLYING THE BITUMEN WATERPROOFING COATING WITH PROFI TIGHT The ground contact waterproofing with Profi Tight must overlap up the masonry wall waterproofing with Sulfatex Grout by at least 20 cm. 7 PROTECTING THE CURED BITUMEN WATERPROOFING When the bitumen waterproofing system has completely dried (confirmed with control samples), it must be protected with Remmers protective sheeting prior to back filling. 8 FITTING THE PROTECTION Snap in the Remmers DS face board to the fixed DS clips without further assembly. 9 APPLYING THE RESTORATION RENDER After 24 to 48 hours dependent on temperature, the Restoration Render can be applied over the hardened bond coat on the wall. 21

22 MAKE THE WEAK POINTS STRONG External waterproofing for ground contact penetration detailing The greater the exposure stress, the more care must be taken with the waterproofing details in the most sensitive areas. Openings for penetrations such as pipe entry ducts are obviously amongst these and are therefore a potential weak point. With Remmers system approach the pipe flange remains reliably watertight in all conditions. When the bond slurry coat is dry, the pipe is fitted and then the flange is securely bonded to the substrate, securing the pipe and the waterproofing system long term. 1 MARK, PREPARE AND CLEAN THE PIPE OR DUCT AND THE SUBSTRATE The substrate must be clean, dry and dust free. Fix the pipe to prevent it moving when the pipe flange is fitted. 2 FIT AND BOND THE REMMERS PIPE FLANGE Apply the adhesive on both the edges of the pipe flange and the substrate then bond together. 3 COMPLETE THE PIPE FLANGE DETAIL Clip the two halves of the collar around the pipe and press onto the substrate, turning slightly to secure. Then apply the final waterproofing system continuously over the substrate and the pipe flange. 22

23 TO ENSURE THEY STAY FLEXIBLY WATERPROOF External waterproofing for ground contact building movement joints All of the existing movement joints in the building structure require special treatment. They should be waterproofed within the waterproofing system by the Remmers waterstopping strip. This special strip has a central elastic tensile zone and the strip can be incorporated in either the Remmers slurry seals or the Remmers high build bitumen waterproofing systems. 1 BRUSH THE LAMINATED JOINT STRIP INTO THE REMMERS BITUMINOUS WATERPROOFING LAYERS The easiest and most efficient procedure is to simply brush the water-stopping strip into the coating. 2 ALTERNATIVELY IT CAN BE BRUSHED INTO THE ELASTOGROUT 1 K On damp substrates the waterstop can first be embedded in the Remmers slurry coating before being brushed with the bitumen waterproofing layers. 3 COMPLETED INSTALLATION OF THE REMMERS WATER- STOPPING JOINT STRIP The flexible central section of the waterstop must not be overcoated with the waterproofing materials. 23

26 26 Internal waterproofing security from the inside

27 KIESOL SYSTEMS: PROVEN FOR OVER 50 YEARS Internal waterproofing Internal waterproofing systems are used if exterior waterproofing is impossible or uneconomic due to the type of construction etc. The decision on the waterproofing cost and effort required obviously depends mainly on the subsequent exposure and the buildings intended use. Kiesol internal waterproofing systems are ideal for the increased requirements of basements and other below ground areas of buildings today. All of the four different grades of waterproofing according to British Standard BS 8102:1990 can easily be obtained with our systematic approach the systems perform so reliably that areas previously only useable as storage or car parking can become additional living space. For smaller areas in particular, Remmers supplies the fastest curing internal waterproofing system on the market (see P. 30). Through this time saving and just a single site visit, smaller areas such as domestic basements can also be economically upgraded professionally. CHARACTERISTICS THAT MAKE THE REMMERS KIESOL SYSTEM SO STRONG 1. Kiesol is an environmentally friendly, water based system and is therefore suitable for use in living areas, archives, and swimming pools and even in drinking water tanks. 2. Kiesol develops water repelling consolidation of the substrate for upgrading old waterproofing systems and injection systems against rising capillary damp etc. 3. Silicification and silica gel formation within the substrate, restrict capillary action and are therefore also water repellent. 4. Because the pore structure is not fully sealed, the system remains water vapour diffusible, unless specifically sealed with Remmers coatings (to meet BS 8102:1990 Grade 4 for example waterproof and vapourtight). 5. Dissolved mineral salts transport to the surface is inhibited and the salts are bound within the system. 6. All of the slurry, levelling and mortar systems are highly sulphate resistant. 7. The excellent bond of and between each of the individual system components, guarantees maximum security, even on extremely damp substrates. 8. Ideal application characteristics, both manually and by spray, provide exceptional economy. 9. The slurry sealant setting process starts immediately the system is applied; this accelerated setting saves time and allows wet on wet working. 10. The substrate surface chemical resistance is increased to a high classification (according to DIN 4030). 11. Over 50 years of successful and practical experience, with numerous system assessments, test certificates and research reports guarantee maximum security and durability for Remmers customers and their clients. 27

28 FROM A GOOD FOUNDATION TO THE FINISHING PLASTER Internal waterproofing and tanking The Kiesol system The Kiesol systems can be installed on almost any masonry substrate. The right procedure for the application of internal waterproofing always begins with sound substrate preparation. All loose or friable materials, including any old coatings or other contaminants, must be removed. Paints and plasters must be removed for at least 80 cm above the water damaged areas. Joints that have deteriorated or are damaged by salts, must be raked out to a minimum depth of 20 mm. When the substrate is correctly prepared, a clean and roughened masonry surface is provided. The adhesion between the individual components of the Kiesol system is outstanding and the system as a whole, bonds effectively and durably with the masonry. 28

29 THE SEQUENCE OF OPERATIONS How this type of waterproofing is achieved 1 PRIMING WITH KIESOL Priming the prepared substrate with Kiesol. Highly absorbent substrates are pre-dampened first. 2 BOND COAT WITH SULFATEX GROUT Within the Kiesol open time, the Sulfatex Grout bond coat is applied by brush. 3 LEVELLING WITH WATERPROOFING FILLER The Waterproofing Filler is trowel applied on the wet bond coat, if required. 4 SEALING COVE WITH WATERPROOFING FILLER The sealing cove is formed with the Waterproofing Filler, using a special coving trowel. 5 THE 1ST WATERPROOFING LAYER WITH SULFATEX GROUT The 1st layer of waterproofing slurry is applied on the bond coat and levelling/coving layers. 6 THE 2ND WATERPROOFING LAYER WITH SULFATEX GROUT The 2nd layer of slurry is applied on the 1st layer wet on wet. Additional layers if required for the exposure conditions are applied in the same way wet on wet. 7 APPLY THE SPRITZ BOND COAT USING PREPARATORY MORTAR This Spritz Bond Coat is sprayed over the entire surface of the slurry, once it has initially stiffened. 8 RESTORATION RENDER APPLICATION IN OLD WHITE COLOUR The Restoration Render in old white is applied after 24 to 48 hours. 9 RESTORATION RENDER FINISHING After its initial set, the Restoration Render must be finished by rubbing over with a float and a little water or scratching ready for covering with a suitable finishing plaster (Fine Render). 29

30 FROM WET TO DRY IN ONLY 3.5 HOURS Internal waterproofing Kiesol Rapid system Priming 2. Bond coat 3. Levelling coat 4. Sealing fillets 5. First 6. Second waterproofing waterproofing layer layer 7. Refurbishment plaster application When everything has to be completed very quickly and economically: With the new Kiesol Rapid internal waterproofing system, it is possible to complete the waterproofing in a single day. The complete waterproofing system from primer to refurbishment plaster, can be installed in just 3.5 hours: Kiesol is used for priming, Sulfatex Grout Rapid for the bond coat and waterproofing, Waterproofing Filler for the fillets and levelling mortar and finally Restoration Mortar, for the refurbishment and waterproofing protection. (An additional bond coat is not necessary in this system). The fast setting behaviour of all four components, allows wet on wet working without any extended waiting times. One visit to site is enough. This system is easily applied and there are only a few products required. This gives the system maximum security and durability, due to the excellent adhesion and performance of all of the components. The overall economy of this system is therefore also outstanding.

31 3 1 2 KEEPING YOUR FEET DRY Internal waterproofing Detailing solution for floor slabs Complete internal waterproofing always includes the floor slabs. Very high quality waterproofing performance is achieved here with KMB (polymer modified bitumen). It has the advantage of improved crack bridging abilities and higher vapour resistance than any cementitious slurry systems. This is particularly necessary in heated basement rooms, for which the latest Energy Saving Building Regulations across Europe require vapour proof sealing and thermal insulation to be provided. 1 PRIMING WITH KIESOL Kiesol is applied to the prepared substrates by spray. Puddling on the surface must be avoided by brushing into the surface. 2 BOND COAT WITH SULFATEX GROUT Within the Kiesol open time, a Remmers Sulfatex Grout bond coat is brush applied. 3 BITUMEN WATERPROOFING WITH PROFI TIGHT After 24 hours waiting time, Profi Tight is applied in two coats. When the waterproofing is dried, it is protected by Remmers 2-ply PE sheeting, which is followed by the thermal insulation, according to the Building Regulations, then the new floor screed. 31

34 34 The art of blocking rising damp for the long term

35 MASONRY INJECTION AGAINST RISING DAMP (CAPILLARY MOISTURE) Horizontal barriers that work Masonry injections against capillary rising damp are designed to form horizontal barriers. These are always combined with other measures such as water-stopping, internal or external waterproofing and refurbishment plaster systems. The site condition survey and analysis determines: the position of these horizontal barriers, the degree of capillary moisture flow and the void volumes, plus it also determines the choice of method: gravity fed or low pressure injection and whether with or without pre-drying masonry requirements. SEAL THE VOIDS, REPEL THE WATER Injection methods work by void impregnation. Gravity fed or low pressure injection, they fill the capillary network of the substrate material, to give a fully impregnated layer within and across the masonry walls. The liquid materials injected into the masonry work as follows: The active substances are deposited in the substrates capillary network and restrict, then block the flow of water. They also seal the capillary walls themselves, which has the effect of producing an unwettable layer i.e. there is no longer any capillary movement of water along the capillaries. The Zarrentin monastery church has been the subject of an independent study for a scientific research project over the past 10 years: The effectiveness of the Remmers Kiesol system that was originally applied still remains fully waterproof and in excellent condition today. KIESOL STOPS THE WATER Kiesol is a water repellent, void sealing material, which is extremely durable. Its long term efficiency is demonstrated by over 50 years of practical experience on many challenging buildings, where waterproofing has been included as part of National Heritage conservation projects. The water transport mechanisms within the masonry substrates are reduced by over 90 %, the salt transport decreases dramatically and Kiesol can even be used where there is high water infiltration and hydrostatic pressure. 35

36 A SIMPLE METHOD FOR DIFFICULT SITUATIONS Masonry injection Gravity-fed injection Gravity fed injection with Kiesol is applied through holes drilled at an angle or horizontally using Injection Cartridges for the material or directly injecting it into the holes using extension tubes with a low pressure gun. This typical method of capillary impregnation by injection, works where the accessible substrate void volume is sufficient to seal the substrate, producing an effective moisture barrier. Alternatively, for weaker substrates and where there are more extensive voids in the masonry, Injection Cream can be used. This Cream formulation can be used where there is capillary moisture penetration of up to 60 %. Where there are also already high levels of moisture penetration, it can also be used in combination with masonry pre-drying techniques. 36

37 THE SEQUENCE OF OPERATIONS First plug then seal 1 PRIMING WITH KIESOL The prepared substrate is primed with Kiesol before plugging. 2 BOND COAT WITH SULFATEX GROUT Within the Kiesol open time, the Sulfatex Grout is applied by brush. 3 LEVELLING WITH WATERPROOFING FILLER The Waterproofing Filler is applied directly onto the wet bond coat to plug the injection areas. 4 DRILLING THE HOLES After plugging the injection area, the 30mm diameter injection holes are drilled at maximum 12.5 cm centres, at an angle of up to BLOWING OUT THE HOLES Carefully blowing out the holes before injection/impregnation is necessary to ensure all of the drilling dust is removed. 6 APPLYING KIESOL WITH INJECTION CARTRIDGES The use of Injection Cartridges ensures that Kiesol can be effective by fully penetrating the wall over a long period. 7 APPLYING INJECTION CREAM BY LOW PRESSURE INJECTION Injection Cream is applied by low pressure Injection as an alternative method. 8 SEALING THE HOLES After the injection process, all of the holes are sealed with Injection Mortar. 9 WATERPROOFING THE INJECTION AREA After sealing the holes, the whole area is waterproofed with Sulfatex Grout. 37

38 WORKING UNDER PRESSURE Masonry injection Low-pressure injection Even with capillary moisture penetration levels of over 60 %, effective horizontal barriers can be formed in the masonry by this method. The masonry is visibly impregnated through an injection and packer system at a pressure of about 5 bar. This method has the advantage of achieving rapid controlled penetration with large quantities of Kiesol or Aida AMI. Security can be further increased where required, by repeating the injection in several phases, over a short period of time and with wet on wet application techniques. 38

39 THE SEQUENCE OF OPERATIONS Creating water barriers under pressure OPTION 1: Low pressure method with Kiesol / Aida AMI This low pressure technique offers a number of advantages. The main ones are controllable and rapid impregnation of the masonry, application of large quantities of Kiesol and use where there are masonry capillary moisture levels of more than 60%. 1 APPLYING KIESOL HORIZONTALLY If void filling is not necessary then the permanent injection packers can be placed directly in the drilled holes. 2 CONNECTIONS TO THE INTERNAL WALLS, VERTICALLY If it is not possible to separate the internal walls, the injection area is first plugged as for Nos. 1-3 on P APPLYING KIESOL VERTICALLY After installing the permanent injection packers, Kiesol is injected into the packers by the low pressure method. OPTION 2: Using the wet on wet method for sealing voids under pressure With the wet on wet method, voids are filled and the injection material is applied to the masonry without the costly and time consuming redrilling. The method involves three stages: 1 VOID FILLING WITH INJECTION MORTAR There are often large voids in the masonry of old walls. These are first pre-filled with Injection Mortar through the special packer systems. 2 PREPARATION As soon as the Injection Mortar begins to stiffen, the special injection needle is inserted through the mortar to create a small duct. 3 APPLYING KIESOL IK The wall is then injected through these same packers with Kiesol IK using the low-pressure method. After removal of the special packers, the holes are sealed with Injection Mortar. 39

40 THE WATER HAS TO MAKE WAY Masonry injection with pre-drying by the heated packer method For substrates with extremely high moisture penetration levels, heated compressed air is forced into the porous masonry through a special packer. The moisture often initially comes out as liquid water under pressure, but this quickly reduces and then when the electric heater is switched on, the remaining water evaporates and is discharged externally as vapour. These packers can then also be used for the injection work. Remmers uses a modular system which is quick to assemble: it can be used in lengths of up to 8.5 m and if necessary it is able to dry several walls at the same time. In only 5 hours the moisture level of a 50 cm thick masonry wall falls from nearly 100 % to below 50 %! 1 ASSEMBLY OF THE EQUIPMENT Individually controllable connections. 2 THE SYSTEM CONNECTIONS Simple screw connections onto the packers fixed in the holes in the wall. 3 THE WATER COMES OUT Extensive warm air circulation in the structure drives out the moisture initially as liquid water and then as vapour. 40

42 42 Refurbishment plaster systems durable protection against salts

43 REMOVING THE THREAT OF EXPANSIVE SALTS Restoration Render and Plaster The main function of refurbishment plasters is to safely store salts deposited from continuous moisture penetration, movement and evaporation, preventing damage due to hygroscopic moisture absorption and expansive crystallisation. For successful external restoration and waterproofing, application of a Restoration Render is also recommended on the internal surface of the walls. The Restoration Render also acts as a water repellent, so that the salts it contains do not reach the surface, even when moisture vapour passes through it. Refurbishment plaster systems for this problem work in two ways: They move the evaporation point from the masonry surface to within the Remmers plaster layer. The salts dissolved in the moisture in the walls can also then safely be deposited and stored within the new Remmers refurbishment plaster, without any possibility for damage. The Render acts as a storage container for the salts. When any moisture diffuses out through the Restoration Render, it leaves the salts that were dissolved in it behind. The salt resistance of Restoration Render systems is so high that one 20 mm thick layer is sufficient, even where the classification is of a Medium level of salt content in the water. (according to German WTA guidelines). Remmers refurbishment plasters/ renders can be used without additional waterproofing up to a substrate moisture content of < 40%. REMEDIAL MEASURES ARE DEPENDENT ON THE SALT CONTENT CLASSIFICATION Salt Salt content level in weight % Chlorides < 0,2 0,2 0,5 > 0,5 Nitrates < 0,1 0,1 0,3 > 0,3 Sulphates < 0,5 0,5 1,5 > 1,5 Classification Low stress Medium stress High stress Salt System Layer thickness content level in mm Low to medium 1. Preparatory Mortar min. 5 System 1 2. Restoration Render min. 20 High 1. Preparatory Mortar min. 5 System 2 2. Undercoat Render min Restoration Render min. 15 A SAFE EVAPORATION ZONE AND SAFE SALT STORAGE Plasters can only meet these requirements if their pore volume and structure is designed with the latest mortar technology. Active capillary network forming agents and capillary wall barrier pore formers, are both included in the formulations, so that these salt storage areas are specially produced in the hardening finishes. The capillary water migration in the capillary pore system of the masonry can then be controlled as required, in conjunction with any necessary waterproofing, by using the refurbishment render system as a safe evaporation zone and a safe salt storage container. Remmers Refurbishment Renders/Plasters perform these functions extremely well. In several parameters they exceed the offical requirements including: Salt storage capacity High sulphate resistance Fibre reinforced for crack-free drying 43

44 System 2 System 1 D D C C A B A SOLUTIONS FOR ALL TYPES OF AGGRESSIVE SALTS Refurbishment plaster system A Preparatory Mortar B Undercoat Render C Restoration Render D Fine Render Since 2005 refurbishment plaster systems have been described and regulated in EN This standard refers to the German WTA data sheet /D Refurbishment plaster systems. This specifies the technical requirements and also gives clear advice on how to plan and install refurbishment plaster systems. The level of salt stress from chlorides, nitrates and sulphates identified in the building condition survey and analysis is classified in one of three levels low, medium or high, dependent on the percentage salt content. Remmers refurbishment plaster systems also act as a moisture-regulating protection system for the internal waterproofing. 1 APPLYING RESTORATION RENDER The appropriate Remmers plaster system is applied with minimum 24 hours between layers. Intermediate layers must be prepared for the next layer by scratching and scoring when wet. 2 SCRATCHING RESTORATION RENDER SURFACES The stiffened Restoration Render surface is prepared for application of the following finishing plaster with a special float. 3 APPLYING FINE RENDER The Fine Render plaster is applied on the prepared surface at a maximum layer thickness of 5 mm then floated to level and profile. 44

46 Special solutions attention to details for success

47 TO FILL VOIDS AND SUCCESSFULLY REFURBISH THE MASONRY Special Waterproofing solutions Voids in the materials of the building fabric can significantly affect their functionality and durability. Remmers supplies state of the art solutions for all types of masonry refurbishment and void filling or sealing problems. Cracks are sealed and waterproofed by grouting Anchors are grouted for stability Water ingress is halted Voids are reliably filled WATER IS QUICKLY STOPPED Special solutions Preliminary water-stopping during waterproofing operations Stopping water ingress represents one of the most difficult waterproofing challenges. Remmers Kiesol systems provide fast stable water-stopping, even under hydrostatic pressure. The main success factor here is the combination of materials technology and sealing methods used. After opening up the damaged area and forming a drainage hole, Aida Waterstop is applied and built round and over the area of ingress. It sets very quickly and is shrinkage compensated, so the water penetration is soon stopped with the final plugs in the centre.

48 EXTERNAL WATERPROOFING WITHOUT EXCAVATION Special solutions Curtain injection waterproofing If it is impossible to excavate the affected walls due to other buildings, services or construction details, then curtain injection waterproofing can be the answer: An injection gel is pumped through holes in the walls from the inside through to the external side. This method can also be used for floor slabs. Remmers Injection Gel PUR is fast-reacting and resistant to dilute acids, alkalis and the salts and gases common in buildings. It has excellent sealing properties and also resists freeze/thaw cycles. The gel also functions as a soil stabiliser and is suitable for use around leaks and where there is high water infiltration through cracks.

49 GROUTING AND SEALING CRACKS EFFICIENTLY Special solutions Crack grouting and sealing Cracks are a common defect, damage or result of damage in concrete floors. Even in new buildings, cracks occasionally need to be sealed before handover, because they clearly constitute an unacceptable defect. The choice of structural or flexible crack grouting depends on the water content in the substrate and the size and nature of the crack. A Structural Engineer should always be consulted. Aida Waterstop is first used to plug water bearing cracks and water seepage or infiltration points. Water ingress can then quickly be stopped with Remmers polyurethane injection resins.
