5 FORMS FOR LOOSE AND LOOSE/FIXED FLANGE JOINT SEALING The limits of water pressure and stress given in the tables below apply to standard uses for a joint width w nom of 20 mm or 30 mm. Different values may be used when precise information on all of the relevant stresses and structural requirements is available. The waterstops should preferably be clamped on the side away from the water.

For clamping on one side, the selection is made in accordance with DIN 18197, the geometry of the cast-in part, plus the clamp type and fixing method. SPECIAL STRESS AND EXPOSURES For special stresses and exposures due to different temperatures or chemical mediums outside the substances or situations specifically defined in DIN 4033, separate tests are always necessary. SYSTEM INFORMATION GENERAL CONSTRUCTION Loose and loose/fixed flange joints are used to solve particularly difficult sealing problems. They demand high standards and accuracy of workmanship and must therefore only be carried out by trained and experienced personnel. As specified in DIN 18197, only butt joints should be formed on site with Tricomer waterstops; the other jointing profiles required should all be factory produced. The factory production of different waterstop systems and profiles reduces the joints required to be formed on site to a minimum.

7 FACTORY PRODUCED JOINTING PIECES Packaged as separate profiles or waterstop system components Standard forms Vertical Flat Flat Flat L-piece cross-piece T-piece L-piece Mirror L-piece, vertical Mirror L-piece, flat Angle L-piece, vertical Angle L-piece, flat Production of these profiles is preferably in 90, or in standard internal or external angles > 60 to 175. Other joint forms are possible on request. Many different special joints exist for standard profiles, as combined joints of various forms and as joint transition pieces. In the standard approach the standard joint profiles are built into the joint waterstopping systems. The sizes of the system components are dependent on the waterstop forms involved and the type and number of joints required. The normal maximum total length of waterstopping systems is up to 25 m maximum (total for all separate lengths). Typical Waterstopping system (as example) 7/12

8 DOCUMENTATION HANDLING OF WATERSTOPS APPLICATION JOINTING ON SITE SITE JOINTS German General Construction approval certificate abp Manufacturer s test certificate, other test certificates as required Regular external monitoring inspection certificates System drawings of the system and components with detailed dimensions Careful transport and handling on site Installation only at waterstop material temperatures 0 C, or as required in the approved anchorage fixing data sheets Protection is required until the waterstopping system is fully cast in Special care to be taken of free waterstop ends Waterstops are to be cleaned before casting in Resin anchors are to be fixed as detailed in their respective s. Clamped flange joints are to be installed by skilled company or personnel trained by Sika Deutschland GmbH. The clamping parts of the waterstops are pressed onto the substrate (concrete or fixed flange). The contact pressure required and the type of anchors and flanges to be used are dependent on the stresses present. The specified tightening torque is to be applied with a torque wrench and to be confirmed / adjusted twice in the time sequence detailed in the specifications. The cast-in parts of the clamped waterstops are installed as specified in DIN The thermoplastic Sika Tricomer Clamped Waterbars are butt jointed together by welding on site. The ends are melted and joined together in their plastic state. Jointing with adhesives is not permitted under DIN Site joints must be formed as stated in the welding instructions. Welding requirements: Minimum ambient temperature + 5 C and dry weather conditions. The requirements and limitations of DIN apply to the jointing techniques. The welding jigs used must allow a weld over the full cross-section of the waterstop, be temperature controlled and allow measured jointing pressure. Site joints must be formed only by trained and qualified personnel. Their welding training completion certificates must not be more than 2 years old. Training courses leading to operative certification are run by Sika Deutschland GmbH, Structural Sealing, Illertissen. The key steps for site jointing and complying with the welding instructions are: 1) Cut the waterstop ends, straight and square 2) Butt joint with welding jig SG 320 L, or in special situations with a welding blade Welding process: Align Heat/melt Change round Joint Together Cool (in ambient temperature Do not use coolant) 3) Inspect and protect the seam as necessary After cooling for about half an hour, the joint is normally finished and may be fixed / installed / stressed. Further steps may be necessary dependent on the joint requirements and the waterstop form. These steps are described in full for all waterstop types in the individual waterstop welding instructions. These instructions are enclosed with every welding jig unit or are supplied direct to the contract on request. All welding work is subject to the relevant local Health and Safety regulations. 8/12

9 Formation of these site joints takes about a half to three-quarters of an hour of working time per joint, dependent on the specific waterstop form, and therefore this time must be scheduled and the work completed properly before the next operations proceed. Two people are required for the welding of site butt joints with a welding iron. For internal construction joint waterstops, a manually welded lap joint is possible (with only 1 person required). WELDING JIGS (PROVIDED ON HIRE ) Welding jig SG 320 L for waterstops up to 320 mm total width Welding jig SG 600 for waterstops > 320 mm to 500 mm total width Clamping bars according to the profiles being used Welding jigs are electrical appliances which are subject to standard regular safety checks (under BGV A 3 for example), which must be scheduled and arranged when due by the hirer. The operating instructions for welding jig SG 320 L describe all of the steps required for waterstop welding and these must be closely followed when forming joints. TOOLS, EQUIPMENT, PROTECTIVE CLOTHING The welding jigs may only be used as described and according to all relevant regulations as stated in the operating instructions.
