4 Sika and Tricosal Waterstops High Quality Joint Waterproing Solutions Introduction Sika and Tricosal have unrivalled experience waterproing all types and construction joints in reinforced concrete structures. Our continuous research and development also ensure the application the latest available technologies in waterproing, especially to modern methods concrete construction and requirements. Providing cost effective, economic and reliably secure solutions for our customers is our priority. Due to the nature these materials, concrete and reinforced concrete structures must always be built divided into sections, by forming joints construction (daywork and isolation) joints and/or (movement) joints. For sealing and waterproing the concrete structure, waterstops are installed in all these necessary joints. The selection the right waterstop material, its overall waterproing concept, design and priles are dependent on the specific structure, its exposure and the construction process. The functions these waterstops are primarily to act as a waterproing seal in the joint, plus to allow the two sections to move independently each other without restriction (free tension).

9 Tricosal Tricomer Produced in accordance with the requirements DIN 181 Tricomer is a combination PVC-P and NBR (nitrile butadiene rubber) compounds. This special polymer was developed and modified in our laboratories to meet DIN requirements. The Tricosal Tricomer material has now been used successfully for nearly years in the secure waterproing joints in concrete structures. Tricosal Tricomer based products have a high elongation at break, excellent resistance to chemicals and ageing, together with a constant elasticity similar to rubber elastomers. It is used where a higher performance the structure and the joint waterproing is required. The Tricosal Tricomer waterstops are connected by thermoplastic welding which makes them easy and practical to use. (s. pages /7) Tricosal Tricomer waterstops are produced in the grade BV (bitumen resistant according to DIN 181). Tricosal Elastomer Produced in accordance with the requirements DIN 78 An Elastomer is an artifical rubber compound based on long chain polymers, cross linked to control their shape and deformation / movement under stress possibilities, by vulcanising them. Their production process is non-reversible, therefore a special jointing process is also required. Tricosal Elastomer waterstops (internal and external types) are used for structures with large potential joint movement, frequent load changes and/ or low temperature exposure, as well as for resistance to very high water pressures. The visible surface the Tricosal Elastomer FAE capping joint priles have a grey cover plate. The priles are manufactured from a UV-stable elastomer compound to suit this type application. Tricosal Elastomer waterstops are connected by vulcanising.

10 Selection the Correct Waterstops Sika Waterbar Introduction Waterstops are used for the waterpro sealing construction and joints against water penetration from percolating ground water and water under hydrostatic pressure, as well as for surface / end capping joints. Joint waterstops in combination with watertight concrete construction techniques must ensure the watertightness the whole structure. There are standard international or national design standards and requirements which must always be complied with and maintained. The correct selection the most suitable and construction joint waterstops is determined primarily by the anticipated water pressure, joint movement requirements and the exposure the joint waterstop. The maximum design water pressure resistance for each waterstop is given in the following tables; these are indicative figures based on our experience and subject, to the correct embedding the waterstop into the concrete structure. The nominal the joints should normally be mm to mm, dependent on the specific waterstop and prile to be used.

26 Potable Water Structures Waterstops Approved for Drinking Water Introduction For potable (drinking) water to be collected and held in service reservoirs without water loss or contamination, watertight construction and joint sealing which is efficient, food-safe, harmless to health and durable is needed. Given the rise in environmental awareness, public and private customers and designers are demanding and specifying higher ecological standards to be used for the waterproing and sealing materials. Fields Application Drinking water tanks and reservoirs Dams, river and canal structures Food processing industry All types wet areas All types structure where micro-organism and pollutants must be kept under control All the products to be used should comply with the strict international and national regulations and approvals covering materials in contact with drinking water. Tricosal waterstops for use in contact with potable water have proven durability and guarantee top quality drinking water, with their functionality being maintained for many years. With our extensive range many other different types products that are also approved for contact with drinking water, Sika has the right sealing and waterproing solution for every project, including concrete and steel protection for contact with aggressive st water.

27 Drinking Water Quality According to the requirements the German specifications DVGW, worksheet W 270, microbial growth can only take place to a very low limit and according to the German KTW recommendations, no harmful contents shall enter into the drinking water. Similar regulations apply in most countries. The Tricosal waterstop range for use in drinking water structures is tested according to the German DVGW and KTW specifications and fulfils all the performance requirements. They are also approved by the Hygienic Institute in Gelsenkirchen for use in contact with food stuffs and drinking water. Tricosal waterstops are made out high quality TPO material and have excellent physical performance properties and can be connected by the usual waterstop welding technology. Handling and installation on site are therefore the same as for general thermoplastic PVC or Tricomer waterstops.

28 Flanged Retrit Joint Sealing Waterstops Introduction Flanged retritted joint seals for waterproing joints connecting new to existing structures are typically one side flanged and one side embedded in new concrete. In addition flanged joint seals can also be used for retrit waterproing existing joints i.e. both sides fixed to the existing concrete; or for sealing joints between separate sections bridge superstructures for example. There is a wide range flanged priles available for use in most difficult applications and highest loads, allowing secure waterproing even in extreme exposed conditions. These factory made waterstopping systems can also be used for loose flange seals or for combinations loose and fixed flange joint sealing. Flanged Retrit Joint Seals should be installed by Pressional Applicators to ensure watertightness in the longterm even in extremely exposed conditions and with high joint movements.

37 For the Protection Our Environment Tested and Approved! Today the environment has to be protected against a multitude chemical substances, which are stored and processed in many facilities. Appropriate containment bunds and secondary containment tanks built in reinforced concrete, therefore require joint waterproing materials with sufficient chemical resistance. The Tricosal Westec waterstop range is produced in a special chemically resistant PE polyethylene material. In comparison with standard waterstopping materials according to DIN 78 or DIN 181 this material is considerably more resistant to most aggressive chemical media. This applies in icular to dangerous hydrocarbon based chemicals (fuels, oils, solvents, etc.). In order to meet strict safety requirements, the Tricosal Westec waterstop system was tested according to The Approval Principles for Joint Waterproing Systems in facilities for the storage, filling and transfer water-contaminating substances ( LAU-facilities ), to confirm their suitability for both function and resistance. It was approved by the German Institute for Construction Technology.

40 Waterstop Specification Design Closed Waterproing System Waterstops must create a closed waterproing system within the reinforced concrete structure. Joint intersections with each other and with penetrations and edges the structure should be made as square as possible. The clearance from the edges the structure should generally be 0. m minimum. The overall waterstop section system specification and method statement for a project are divided into logical sections. These are linked to the drawings the system and its components, their factory prefabrication or assembly and for their installation on site. This also provides the project documentation and confirmation the specific waterstop qualities required. The waterstops should conform with the local regulations and specifications. Component d Embedment depth Cover Waterstop Rule The component d around internal waterstops should be at least equivalent to the waterstop a (embedment depth cover). A component 0 mm is sufficient for 3 mm wide waterstops according to DIN 181 (types D and A). The choice waterstops is based on the load and exposure, e.g. in accordance with DIN V Our Product Engineering dement will be pleased to assist you in your projects. Waterstop a Bending radius r 2 cm 1 cm 0 x Stop anchor depth f (Example: f = mm r 1,0 m) x Prilhöhe a (Example: a = 70 mm r 2, m) Bending Radius r When there are changes direction perpendicular to the waterstop level, waterstops may be bended strictly regarding the indicated minumum bending radius r. If the required bending radius r cannot be maintained, a factory-made vertical angle should be specified. z x y Bending radius r x Otherwise z Mitred angled joint (factory made joint) y mm Concrete and Reinforcement Cover The clearance between waterstop and reinforcement shall be at least mm. mm mm mm

41 ca1 mm Joint filler plate mm mm Horizontal Waterstop Installation in Slabs Internal waterstops in horizontal base or deck slabs should be installed in a v-shape at an angle about 1 upwards, to allow the waterstop sides to be embedded without voids and to prevent concrete honeycombing (from grout loss / segregation during concreting). mm Ceiling Use External Waterstops External waterstops are always fitted on the water contact side. They must not be casted in on the top horizontal and low angled components (due to the risk air entrapment and voids). External waterstops must be given adequate durable protection against mechanical damage (e.g. by backfilling with soil, sand, similar fillers without angular crushed stone). Floor slab/wall Design Constraction Joints Expansion joint waterstops are also used in contraction joints. If shear movement can occur in a contraction joint, a deformation void must be created using an encased centre-bulb (e.g. waterstop type Tricosal FMS 00 HS Elastomer). Design Wide Joints For joints with a nominal joint Wnom mm and if shear force VY>Wnom occurs, measures must be taken to prevent any possible damage to the waterstop from the concrete edges (e.g. use encased centre-bulb waterstop type: Tricosal FMS 00 HS Elastomer). Minimum Joint For the joints in service, under their intended deformation, the joint at a nominal Wnom = mm must not be less than 1 mm and at a nominal Wnom = mm, not less than mm. Otherwise a deformation void must be created by forming an encased centre bulb (e.g. waterstop type Tricosal FMS 00 HS Elastomer see Contraction Joint above). 1 mm Joint Seal at Open and Below Ground Ends To protect joints from contamination, external waterstop should be installed at below ground ends with a suitable joint sealant or capping waterstop at the open air ends. 0 I 1

42 Waterstop Handling Guidelines Storage Protected Storage When delivered to site, the waterstop products must be unloaded carefully and inspected immediately for completeness and integrity, including form and dimensions. Before installation the waterstops must be kept in a sheltered place on boards or some other firm base (e.g. pallets, concrete surfaces) and protected from contamination or damage. Storage in Summer Waterstops must be protected from direct sunlight, specially in summer, e.g. by covering. In high outside temperatures waterstops must be taken to the point installation and laid out under no tension. Storage in Winter Waterstops should be kept in covered storage if possible and then be put in heated rooms for at least one full day prior to their installation, to make their handling and installation easier and less prone to damage (thermoplastic material).

43 Waterstop Installation Guidelines Installation and Fixing Cleanliness and Integrity Waterstops must not be installed if they have suffered deformation or damage which might impair their function. Waterstops must be installed without creasing or distortion. Deformation in external PCV-P, TPO or Tricomer waterstops caused during storage or handling (e.g. creasing or distortion the anchors) should be corrected by stretching on a level base and heat treatment. Waterstops can only be installed at a material temperature over ±0 C and in weather conditions not endangering the safe installation the whole waterproing system. Fixed in a Stable Position Waterstops should be installed in their specified position, symmetrical to the joint axis, and be fixed so that their position can not change or move during the concreting works. mm Concrete and Reinforcement Cover The minimum clearance and concrete cover shall be at least mm. mm mm mm 2 I 3

44 Waterstop Installation Guidelines on Site During the Waterstop Installation Fixing Internal Waterstops Internal waterstops are anchored to the reinforcement. The waterstops are fixed to the edge anchors with the special waterstop clip or, in the case waterstops with steel plates (FMS, FS) to the edge perforation the steel plates at maximum intervals 2 cm. ca1 mm Joint filler plate mm mm Horizontal Waterstop Positioning in Slabs To prevent honeycombing or concreting voids, the internal waterstops in bases and decks should be installed in a v-shape at an angle about 1 upwards. mm Reinforcement Fixing interval: 2 cm Fixing External Waterstops External waterstops for walls are fixed with nails to the formwork at the edges, nailing plates with an embedment depth maximum 1/3 nail length and bent around approx.. If there is a risk a stop end anchor snapping (e.g. due to concrete dropping too heavily by mistake), it should be fixed to the reinforcement with waterstop clips every 2 cm, e.g. the top stop end anchors the waterstop system in the base / wall joints. External waterstops for horizontal installation under bases are fixed directly to the concrete blinding. ca. 1,0 m Free waterstop end Free waterstop end 0, m 0, m Butt joint Butt joint Spacing Between Joints in the Waterstops Themselves The spacing between two joins in the waterstops themselves should be 0.0 m minimum. In every configuration the length the free waterstop ends should be 1.00 m minimum so that these connection joints can be formed easily and correctly on site. 1,0 m Butt joint 0, m 1 st Concreting section Tight Bulkhead Formwork When installing the waterstop system, ensure that the bulkhead formwork is tight, stable and immovable. The stopend formwork must lie tight against the waterstops. The waterstop must be protected from damage before and during the concreting works.

45 During the Concreting Works Embedding External Waterstops Waterstops must be free from contamination and ice when casted in. If necessary they should be cleaned before concreting (e.g. removal any accumulated site debris such as sawdust, sand, concrete residues, cement laitance, oil, grease, snow, ice etc.). This is icularly important for external waterstops in the base a structure. Casting Without Honeycombing or Voids The waterstops must be fully enclosed in concrete and the concrete must be free from voids. Make sure that there is a low concrete drop height, good flow without segregation and even distribution. cm Poker vibrator Poker vibrator Clearance Between Poker Vibrators and Waterstops The poker vibrators must never touch the waterstop or its fixings (minimum clearance cm). It is usually preferable to compact around external waterstops with external vibrators, which will also give better compaction around stop end anchors. Protection Protection Exposed Waterstops On Site The waterstops should be protected from damage until they are fully casted in. Examples suitable protective measures are: For waterstops in walls: cover reinforcement ends with boarding, box in or roll up and suspend the waterstop till later For waterstops to be trafficked: completely cover or bed in sand For waterstop ends to be exposed for some time: box in to fully protect Striking Formwork Striking Around External Waterstops Take great care that external waterstops do not come loose during striking adjacent or attached formwork. Extend the time before striking these areas if necessary. I

46 Equipment, Tools and Accessories For the Welding Thermoplastic Waterstops Introduction Joints between thermoplastic waterstops are made with a heat welding process. This process is reversible. The principle welding consists stening the mating surfaces both the two s to be joined by heating them to the melting temperature, quickly pressing them together, and allowing them to cool. Welding is not possible merely by heating and stening one the two pieces to be welded together. Although the welding thermoplastic materials is easier and cheaper on site than the vulcanising Elastomers (artificial rubber based materials), it demands more manual skill and dexterity, as well as ensuring good workmanship and quality control.

48 Equipment, Tools and Accessories For the Vulcanizing Tricosal Elastomer Waterstops Introduction Joins Tricosal Elastomer (rubber) waterstops are made in a vulcanizing process. This process is irreversible, i.e. it can be carried out only once and therefore requires careful, consistent and complete execution all the working steps. Standard junctions, e.g. flat cross, vertical T, flat edges etc. are all prefabricated in our factory using specialist equipment i.e autoclaves. Therefore only the butt joints should be made on site.
