4 PENTAFLEX DESIGN AND CONSTRUCTION OF COMPONENTS IMPERMEABLE TO WATER* FUNDAMENTALS OF SEALING TECHNOLOGY ACCORDING TO WATER PROOFING GUIDELINES In order to prevent ingress of water into structures, water impermeable reinforced steel structures, so-called "white tanks", have been fabricated for over 30 years. Thanks to these long years of practice and experience, this method of construction represents an economical way of stopping the ingress of water. Furthermore, the water proofing guidelines represent the generally recognized current technical standard with regard to the "white tank". The watertightness of a structure is characterised by the limitation of water ingress through concrete, construction joints and crack inducer sections, mounting parts and cracks. THIS MEANS: Sealed construction of all joints Meeting high requirements of the concrete Maintaining the minimum thickness for structural elements Crack limitation in structural components Maintaining a minimum height of the pressure zone Methodical arrangement and design of construction joints or sections of the crack inducer if crack formation is expected DESIGN BASICS CONSTRUCTION METHOD WITH DECREASED FORCE STRESSING: Force stressing on concrete that can lead to water-channeling cracks is reduced by suitable construction, concrete-related technical and design measures. As part of this are, e.g. level undersides on floor slabs with a layer of film, use of concrete receptors with low development of hydration and heating and extended after-treatment measures. METHOD OF CONSTRUCTION WITH LIMITED CRACK WIDTH: The method of construction with crack width limitation applies as the second approach to the solution. In this case, an increased reinforcement content of the concrete construction controls, or limits, the crack width. METHOD OF CONSTRUCTION WITH SUBSEQUENT SEALING: In the case of the third method of construction, no special measures are introduced prior to the construction and formation of the cracks channelling the water are accepted. Later these are tightly sealed in accordance with the relevant guidelines. However, this method of construction may not be used for residential buildings. *Source: "Bulletin Comments on the DAfStb guidelines on water impermeable concrete structures" from the German Committee for Reinforced Concrete (DAfStb) 4

5 PENTAFLEX DESIGN OBJECTIVES A design of the arrangements must be carried out and the defined designs documented. For designs in accordance with water proofing guidelines, close collaboration between the different design areas is necessary. THE FOLLOWING ARE THE PARTICIPANTS: Object designer/architect Geo-technician (if required) Bearing structure designer/water proofing specialist Successful tenderer (work scheduling) In agreement with the construction participants depending on the complexity of the project: concrete Technologist, construction physicist, building engineering designer. The function and required utilisation of the structure, together with the regulations regarding fitness for purpose must be defined and documented. THE FOLLOWING POINTS MUST BE CLARIFIED: Impact: the stress on the structure as a result of standing water or soil humidity Utilisation: which requirements need to be met by the structure in regard to impermeability to water The result of the first two design stages form the basis for further design measures. The impermeability to water of a structural element is determined by several factors. THE FOLLOWING POINTS ARE TO BE ACCOUNTED FOR IN DETAIL, BOTH INDIVIDUALLY AND IN THEIR COMBINED EFFECT: Selection of the concrete Dimensions of the structural components and reinforcement channels Avoidance or sealing of cracks or limitation of the crack width Planning of all joints and penetrations Planning of construction sequence, concreting sections, construction joints and sections of the crack inducer Where necessary, account must be taken of aggressive water and soil DEFINING THE WATER PROOFING GUIDELINES The water proofing guidelines determine and define the specifications for concrete structures impermeable to water. These are regulated in relationship to the stress and utilisation classes. STRESS CLASS There are two stress classes. They are differentiated by whether the flow of water is directly on the structure or the concern is only with soil humidity or, as the case may be, with seepage water. Stress class 1: for pressurised and non-pressurised water as well as intermittently trapped seepage water Stress class 2: for soil humidity and non-trapped seepage water UTILISATION CLASS The water proofing guidelines differentiate between two utilisation classes. They are dependent on the function of the structure and the requirements on the thickness, and must be defined accordingly. Utilisation class A No water passage in flowing form No points of humidity on the surface No cracks and joints channelling water Application examples: Residential building, storerooms with high-grade utilisation Utilisation class B Areas of humidity permissible From temporary up to self-healing water-carrying cracks permitted No gathering of water on the surface Application examples: Underground car parks, installation and supply shafts, storerooms with low-level requirements The concreting work, the after-treatment and the structure monitoring must be executed in accordance with DIN

6 PENTAFLEX REQUIREMENTS ON THE CONCRETE In the selection of a suitable concrete it should be noted that, in addition to the requirements arising from the exposure classes from DIN 1045 pertaining to the structural component, the requirements on a concrete with high resistance to water ingress must also be satisfied. A sufficient workability can be guaranteed by flow class F3 or greater. In the design of Water proofing structural components in the minimum component thicknesses, a water/cement ratio of 0.55 and for walls, in addition, a largest particle size of 16 mm, must be used for stress class 1. For a head of more than 1.0 m (e.g. for walls) a designmix with particle less than 8 mm must be used in the foot area at a height of 300 mm, in order to ensure a zero defect installation of the concrete. STRUCTURAL COMPONENT THICKNESS Minimum thicknesses for the structural components are specified in the water proofing guidelines: The minimum thickness and construction of the structural components must be selected such that the concrete structural components can be concreted technically correctly whilst adhering to the concrete cover, the required reinforcement location, joint sealing and the mounting components. In addition to all the other required features, it must also be possible to fulfil the support and sealing function. Over and above the minimum dimensions, the following apply to the clearance dimension b W,i between the reinforcement layers (for in-situ concrete) or for the spacing of the interior surfaces of the form (for element walls) in order to ensure a technically correct installation of the concrete: for a largest particle of 8 mm b W,i 120 mm for a largest particle of 16 mm b W,i 140 mm for a largest particle of 32 mm b W,i 180 mm If component thicknesses result from this that are larger than the minimum dimension in the table above, these become the standard. Type Walls Floor slab Minimum thickness in mm Stress class In-situ concrete Element walls Pre-cast components b W,i b W,i external form internal form reinforcement reinforcement 6

7 PENTAFLEX PROOF Proof of impermeability to water is an additional proof of fitness for purpose for DIN , Clause 5.4.1, Section 2. LIMITING THE CRACK WIDTH For bending cracks resulting from stress and forces it must be proved for utilisation class A, stress class 1, that the pressure zone height (x) satisfies the condition x 30 mm and 1.5 D max, whereby D max is the largest diameter of the aggregate. If there is an acceptable temporary ingress of water through separating cracks for stress class 1, the calculated widths of the separating cracks in relationship to the pressure gradients are to be limited according to the table. UTILISATION CLASS PROOF FOR UTILISATION CLASS A The required proofs conform with the selected design fundamentals of utilisation class A. For this, verification is needed that no separating cracks occur in the concrete as a result of force. The exceptions here are the planned, sealed joints. To this can be counted the crack inducer, construction and expansion joints through the arrangement of which, at specified spacings, the reduction in the force on the structural components follows. The limitation of the incident crack widths results from the design of the crack inducer and construction joints and/or the arrangement of the reinforcement. Pressure gradient h w /h b * permissible crack width w [mm] (calculated value) > 10 to > 15 to * h w = pressure head of the water in m h b = component thickness in m If the table values are adhered to, it can be assumed that the initial water ingress will be greatly reduced with time through self-healing of the cracks. Humidity spots on the surface of the structural component cannot, however, be ruled out with certainty even at a later time. For stress class 2, the permissible crack width for walls w 0.20 mm applies to the calculated value, for floor slabs proceed according to DIN , Clause Example of utilisation class A: Standard for housing and rooms with high quality use PROOF FOR UTILISATION CLASS B The required proofs conform with the selected design fundamentals of utilisation class B. Their requirements are met through a limitation of the separating crack widths with the assumption that the cracks are self-healing. The limitation of the incident crack width results from the design of the crack inducer and construction joints and/or the arrangement of the reinforcement. Example of utilisation class B: Single garages, underground parking and storage rooms with lower demands 7

8 PENTAFLEX REINFORCEMENT AND CONSTRUCTION REGULATIONS The configuration of the reinforcement in the structural components must be designed such that it is possible to have a faultless insertion and compaction of the fresh concrete. Water proofing components of stress class 1 should be fabricated with a double-sided mat reinforcement composed of longitudinal and transverse reinforcement. The exception to this are prefabrications of stress class 2. The construction joints must be defined by the designer and represented in a blueprint. In accordance with the defined stress and utilisation class, all joints in Water proofing construction components must be permanently guaranteed by a complete sealing system that is impermeable to water and uniform. Crack inducer sections are caused by sufficient weakening of the concrete section (at least 1/3 of the structural component thickness) and must be sealed for the smallest, but nevertheless appreciable, movements. Special crack inducer elements guarantee both requirements and are thus suitable for structures of utilisation class A. Element wall splices are to be designed as crack inducer sections. COATED LAMINATIONS A joint sealing system must constitute a closed system and have a sealed contact to all of the connection and crossing points. In the case of joint sealing for crack inducer sections it must be ensured that the sealing effect is maintained in the event of crack formation and the associated widening of the joint. An integral joint laminate does not absorb any kind of shear force. The lamination must demonstrate sufficient elasticity to survive any possible deformation without damage. This will prevent any temporary seepage of water. For coated laminated joints, considerably less anchoring depth in the concrete is required, as is the case, for example, for uncoated joint laminations. The necessary minimum anchoring depth can be taken from the proof of fitness for purpose (abp). JOINT SEALING Only products holding a proof of applicability may be used for sealing joints in water proofing structural components. A general building authority approval (shortened to abp) provides this proof for non-standardised products. All of the joint seals that connect with the concrete must be precisely placed according to the design, connected to the splices and forcefully and permanently secured in position prior to the concreting operation. 8

9 PENTAFLEX PRACTICAL INSTRUCTIONS Extract from the practical instructions for the basic blueprint "Method of construction with reduced force loading": CONSTRUCTION SYSTEM FOR FLOOR SLABS At least one layer of PE film must be laid on a sub-base underneath the floor slab. The minimum thickness of the floor slab is based on the water proofing guidelines. For pressurised water this is 250 mm. The concrete cover of the upper layer of reinforcement is the responsibility of the building contractor and must be precisely complied with. This is a prerequisite for the pressurisedwater- tight installation of the PENTAFLEX joint system. From experience the minimum degree of reinforcement of the floor slab is at least approx. 0.15% of the concrete section on both sides. If the proof of stability provides for a higher reinforcement content, this must be installed. This minimum reinforcement is to be arranged crosswise in two layers. Re-entrant corners must be secured by a diagonal reinforcement (e.g. 3 pieces Ø 12 above and below). The required wall connection reinforcement, e.g. Ø 8 nails with predetermined spacing for prior anchorage. Otherwise compliance is required with the reinforcement guidelines of DIN CONCRETING The grades of concrete in accordance with DIN 1045 II/EN206 must be adjusted to take account of the required exposure class and the special requirements of the building provisions. If the consistency for processing the concrete on the building site is finally discontinued, a water-reducing admixture (FM) must be used. At the same time it must be guaranteed that any concrete additives that have already been added are compatible with the water-reducing admixture (FM). The maximum amount of additive according to the manufacturer s instructions must not be exceeded. When concreting the floor slab, make sure that the concrete is introduced and compacted fresh on fresh. In the area of the PENTAFLEX elements care is required when inserting the concrete. If the floor slab is thicker than 400 mm, the concrete must be inserted and compacted in two layers (fresh on fresh). To facilitate after-treatment, the concrete slab must always be covered with film and must be protected from strong solar radiation with water and from frost with heat protection mats. PROVISIONS WHEN CONCRETING WALL ELEMENTS Due to the small cross section of the core concrete, special care is required when concreting the core of the element wall. Initially it is essential to check the filling area of the element walls for loose assembly elements, impurities and contamination of the joint elements. Where necessary these must be removed. The surfaces of the concrete form that face the core must be wetted before concreting. The corner and straight splices of the wall elements must be secured against the concrete pressure using the specified formwork pressure retaining elements and supported with angled braces. The concrete is introduced in layers of maximum 800 mm and compacted in accordance with the formula: "diameter of the vibratory concrete poker x 10 = efficiency." The vibratory concrete poker is inserted quickly and slowly withdrawn again. The poker is inserted far enough so that the layers bond with one another (needling). The layers must be introduced fresh on fresh. Up to a height of at least 300 mm, a concrete mix should be used with a largest particle size not exceeding 8 mm. This ensures a zero defect attachment to the base of the wall. For windows and other recesses the concrete is filled on one side until it comes smoothly out on the other side.

10 PENTAFLEX KB PENTAFLEX KB ETA-15/0003 JOINT PLATE THE PRODUCT PENTAFLEX KB elements are fully coated on both sides with a special coating. The connection of the special coating with the fresh concrete reliably prevents water infiltrating the joint system. A concrete covering of 30 mm is enough to withstand a water pressure of 5.0 bar*. The high elasticity of the coating ensures a secure seal when the concrete components shrink. The individual elements are 2.00 m long and 167 mm or 80 mm high. They are provided with a divided protective film on both sides that is only removed immediately before concreting.

16 PENTAFLEX KB PLUS PENTAFLEX KB PLUS COMBINED SEAL AND EQUIPOTENTIAL BONDING CONDUCTOR ETA-15/0003 THE PRODUCT The combination of seal and foundation earth double security in one work step: a seal which resists pressurised water and also acts as a foundation earth. The product benefits of the tried-and-tested PENTAFLEX KB joint plate remain the same: water pressure tested up to 5.0 bar, approved up to a water pressure of 2.0 bar. Tests, occasionally up to the highest lightning current class (class H), have been successfully carried out at the high-voltage laboratory of the University of the German Federal Armed Forces in Munich. This means that the PENTAFLEX KB Plus product can be used universally as a foundation earth. FEATURES Approved at the European level with ETA-15/0003* CE mark* Twice as reliable due to the combination of tried-and-tested PENTAFLEX quality seal and foundation earth Material savings Reduce installation time Optimal warehousing The PENTAFLEX FTS, OBS, ABS connection elements and PENTAFLEX KB corner can be connected in any situation APPLICATION AREA The foundation earth is an integral part of the electrical services of the building. It is part of the equipotential bonding of the building services and, if necessary, an element of a lighting protection system. The foundation earth normally consists of a closed ring-shaped steel band. The steel band is embedded in the concrete of the foundation and the walls it supports. The PENTAFLEX KB Plus product therefore has two functions: when installed as ring-shaped sheet steel element in the foundation, it acts as a seal and also as a foundation earth. * referring to the function as joint tape sealing 16

17 PENTAFLEX KB PLUS TECHNICAL INFORMATIONS BASE ELEMENT PENTAFLEX KB 167 The base element is a steel plate with full-surface coating Dimensions: l = 2000 mm b = 167 mm t = 1.2 mm PENTAFLEX OMEGA PLUS STIRRUP The base elements are secured with an interlocking, electrically conductive connection at each joint using the PENTAFLEX Omega Plus stirrup. At the same time, the fixing points ensure that the base elements are held securely in place ready for concreting. 2. PENTAFLEX RETAINING STIRRUP Retaining stirrups (see page 14) should be used additionally in between the PENTAFLEX Omega Plus stirrups to fix the base elements, such that they are secured at least once per running metre PENTAFLEX PLUS MFA CLAMP With the MFA clamp, both round and flat conductors can be connected at any point on the PENTAFLEX KB Plus equipotential bonding conductor. This allows the creation of connecting lugs or cross-connections, for example. 4. CONNECTING CLAMP The connecting clamp ensures that the PENTAFLEX KB Plus equipotential bonding conductor has an electrically conductive connection to the reinforcement. One connecting clamp is required per PENTAFLEX Omega Plus stirrup. 17

18 PENTAFLEX KB PLUS INSTALLATION INSTRUCTIONS NOTE: Electrical acceptance testing must be carried out on bridge connectors at expansion joints, in line with current regulations

19 PENTAFLEX KB PLUS TECHNICAL INFORMATIONS DETAILED SOLUTIONS Expansion joints must be bridged by water-impermeable electrically-conductive means. These joints are sealed using the tried-andtested PENTAFLEX FBA joint tape connector. The expansion joint connector is connected to the PENTAFLEX KB Plus base element. The overlapping areas are fixed using the PENTAFLEX Plus clamps. According to DIN 18014, expansion joints must be bridged using electrically-conductive expansion strips. These commerciallyavailable expansion strips are normally connected to commercially-available fixed earthing terminals. An electrically-conductive connection is then established via the PENTAFLEX Plus connector between the fixed earthing terminals and the PENTAFLEX Plus clamps. The clamps and connectors must be assembled in accordance with the installation instructions. A schematic representation of the bridging of an expansion joint is shown left. 19

20 PENTAFLEX KB PLUS TECHNICAL INFORMATIONS GENERALLY The PENTAFLEX KB Plus element is essentially used and installed like a conventional equipotential bonding conductor. It is also essential to create a closed electrically conductive ring in the outer area of the building foundation with this element. According to current regulations, the equipotential bonding conductor must be connected to the reinforcement every two metres. Commercially available connecting lugs or fixed earthing terminals can be connected without any problems, and are then linked to the main earthing rail, the lightning protection system or an extension of the earthing system such as a ring earth electrode or earth rod. This means that PENTAFLEX KB Plus can be used universally. DIN 18014: : WHITE TANKS The installation of a foundation earth in new buildings is mandatory according to the German "Technische Anschlussbedingungen" (technical connection requirements, shortened to TAB) for network operators, and the requirements in the DIN VDE (VDE ) and DIN standards. DIN 18014, "Fundamenterder Planung, Ausführung und Dokumentation" ("Foundation earth electrode Planning, execution and documentation"), which was first published in March 2014, stipulates that for water-impermeable concrete in accordance with DIN EN 206, and in the specific case of the construction of a "white tank", earthing is to be carried out using a ring earth electrode outside of the foundation. Furthermore, regulations stipulate that an equipotential bonding conductor must be laid inside the building foundation to control the potential when using a ring earth electrode. According to DIN 18014, equipotential bonding conductors, and therefore also the PENTAFLEX KB Plus, must have an electrically conductive connection to the reinforcement every two metres. For this purpose, the PENTAFLEX Omega Plus stirrups are attached to the panel joints, and one of the bases is bolted onto the reinforcement using KB Plus connecting clamps. The maximum permitted mesh sizes of 20 x 20 m for equipotential bonding conductors are achieved with conventional earthing bands connected to the PENTAFLEX KB Plus outer ring by means of the multifunction clamp. The required connection every 20 m to the ring earth electrode, which needs to be installed on the outside of the building, is achieved using the multifunction clamp, in the same way as with the connecting lugs or fixed earthing terminals. It is possible to use all common accessories without any restriction. It is important to ensure that wall entries are made sufficiently far above the design flood level, or that waterimpermeable penetration is used. PENTAFLEX KB PLUS PENTAFLEX KB Plus has been tested for use as an equipotential bonding conductor by the VDE (the Association for Electrical, Electronic & Information Technologies). It has proof of usability in the form of a general supervisory test certificate for its function as a joint seal for white tanks in pressing water. 20

21 PENTAFLEX DFA PENTAFLEX FBA JOINT TAPE CONNECTION THE PRODUCT The PENTAFLEX joint tape connector FBA is a clamping device which connects PENTAFLEX elements to all types of expansion joint strips. The joint tape connector is attached to the expansion joint strip at the end piece of the PENTAFLEX element via a screwtype clamping device. ASSEMBLY The connection of the FBA to the expansion joint strip is made using a screw-type clamp connector. Holes must be made in the expansion joint strip so that the FBA screws can be pushed through the expansion joint strip. The required installation depth in the floor slab must be observed. The rubber swell strip is inserted between the joint tape connector and expansion joint strip. The clamping device is completed by the press-on flange and held down by butterfly screws. The joint tape connector FBA is connected to the PENTAFLEX KB in a similar manner to that described in the installation instructions on page 12. DIMENSIONS AND DELIVERY The PENTAFLEX joint tape connector is supplied with 2 joint clips

30 PENTAFLEX OBS INSTALLATION INSTRUCTIONS 1 2 Remove all films from the PENTAFLEX OBS elements. Insert a suitable stop end, nominal size c nom, in the formwork exactly at the location where the prebreak should be (level of the assembly sheet steel). 3 4 Install the OBS element in the wall formwork between the outer and inner reinforcement layers. Tie wire is used to attach it. This is guided through the holes provided in the assembly sheet steel and fixed to the reinforcement. The position of the OBS element must be fixed so that the assembly sheet steel is immovable at the level of the planned pre-break point; this means that the sealing plane will be exactly parallel with the surface of the formwork on the axis of the floor/wall joint seal. The OBS element is then attached to the PENTAFLEX KB by overlapping at least 50 mm and pressing the coated sheet steel firmly together. At temperatures below +5 C, the abutting surfaces must be heated. 30

31 PENTAFLEX OBS 5 6 Each connection location must be secured with two cross clips. Before the wall formwork is closed, a suitable formwork, e.g. a trapezoidal strip must be attached true to size in the axis of the OBS element assembly sheet steel. Care is required when concreting to ensure that the OBS element is not exposed to concrete pressure on one side. Always keep the pouring height equal on both sides. Joints and connections must be fabricated and secured using the connections specified in points 3. 31

36 PENTAFLEX STK PENTAFLEX STK SOUND ATTENUATING CAGE THE PRODUCT The PENTAFLEX STK sound attenuating cage for precast walls is a two-part joint cage element made from galvanised construction steel and hydrophobic soft fibreboard. The joint cage element prevents the formation of concrete bridges and therefore acoustically isolates the wall. The integral stirrups guide the joint strip, prevent collapse during concreting and thus guarantee reliable sealing of the cavity joint. The PENTAFLEX sound insulation strip is an elastic joint strip with PENTAFLEX coating in the bonding area of the floor slab and includes a pre-mounted PENTAFLEX expansion joint connection for connection to the PENTAFLEX KB in the base/wall joint. 36 FEATURES Sound insulation tested Quick and easy assembly Reliable sound attenuation Reliable sealing of the separating joint Straightforward and reliable connection with the PENTAFLEX KB joint elements APPLICATION AREA The PENTAFLEX sound insulation joint system is predominantly used in terraced or semi-detached houses. It can be used either with an element wall construction or for in-situ concrete construction. The Improvement Joint insulation degree K ij = 17,2 db houses are insulated acoustically using the PENTAFLEX STK sound insulation cage. The building joint is sealed against pressurised and non-pressurised water by the PENTAFLEX sound insulation joint strip. This results in a closed joint system as required by the water impermeability guidelines. It is recommended that a surface seal for protecting the external insulating panel is used to ensure that sound insulation values remain constant in the long term. Other measures are necessary in the area of the floor slab and the separating walls of the building. A separate floor slab enables the sound insulation cage to also be used horizontally.

37 PENTAFLEX STK TECHNICAL INFORMATIONS TECHNICAL DATA The PENTAFLEX sound insulation joint reliably performs three tasks: Sealing the building joint Reliably fixing the PENTAFLEX sound insulation joint strip Acoustic decoupling of components There is no requirement for a separate stop end in the joint. During concreting, make sure that the formwork is filled evenly on both sides.
