The following points should be kept in mind for optimum performance ▪ Transport and handling on site Installation at ambient and material temperatures ≥ 0°C ▪ Protection until the water-stopping system is fully cast in the concrete ▪ ▪ Special care to be taken of free waterstop ends ▪ To be cleaned before being cast in concrete ECOLOGY,
HEALTH AND SAFETY User must read the most recent corresponding Safety Data Sheets (SDS) before using any products. The SDS provides information and advice on the safe handling, storage and disposal of chemical products and contains physical, ecological, toxicological and other safety-related data.
APPLICATION INSTRUCTIONS
Installation Install directly on the concrete blinding, in the external formwork or weld to the Sikaplan® waterproofing membrane. Nominal Joint Widths The normal joint width is External movement (expansion) joint Jointing at site: The thermoplastic Sika Waterbar® WP AF-28 IN and the detailing / jointing pieces are connected with a Sika® Waterbar Splicing Iron.The welding edges are melted in the process and fused permanently together whilst in the plastic.Jointing the Sika Waterbar® WP AF-28 IN together with adhesives is not permitted. All on-site welded joints must be formed as stated in the Sika® Waterbar welding instructions/ Method Statement. Environmental Requirements: A minimum ambient temperature of + 5°C and dry weather conditions are required for welding on-site. Factory Produced Jointing Pieces (External Waterbars) Only transverse butt joints shall be formed by welding on site with Sika Waterbar® WP AF-28 IN. All of the other junctions and joints shall be produced with prefabricated sections. These are available in many different configurations and detailing sections, in order to reduce the number of joints required to be formed on each site to a minimum. The standard joint detailing sections for External Sika Waterbar® WP AF-28 IN include the following: ▪ Cross piece flat ▪ T-piece flat ▪ L-piece flat Special Notes On Installation External Sika Waterbar® WP AF-28 IN waterstops are installed flush with the external face of the concrete. Do not install this type of waterbar on the top surface of horizontal or only slightly sloping concrete.In situations with negative water pressure external waterbars cannot be used
