This profile creates a barrier to water trying either to enter or leave the structure. Its ability to withstand pressure from both sides makes Sure-Stop “CB” ideal for all water retaining and water excluding structures such as reservoirs and sewage treatment plants. The central bulb enables it to be safely used in joints where movement may occur. Sure-Stop “CB” can be used in horizontal and vertical applications for expansion, construction and contraction joints. Fixing Sure-Stop “CB “ It is important that all waterstops are held securely during the concrete pour and that the concrete is properly compacted to remove voids and porous areas. Where reinforcing steel exists, sufficient space must be available to assist compaction. A series of eyelets have been formed into the outer flanges of the profile so the waterstop can be quickly wire-tied onto the neighbouring steel reinforcement without the risk of water ingress due to the profile falling over. Sure-Stop “RG” Externally Placed Waterstop Externally placed profiles are designed for use in floor and basement areas in horizontal and vertical joints. Sure-Stop “RG” profiles are located on the external face of the concrete. The specially designed keys enable compaction to be obtained around the waterstop, bonding the concrete and waterstop together forming a positive water barrier. Sure-stop “RGX” For use in expansion, construction and contraction joints, the flat top bulb section allows support for any joint filler and allows for any movement in the structure. The bottom of the bulb has a “v” shaped notch so that should the joint open beyond the capacity of the PVC bulb, the bottom of it will tear along the notch and permit the bulb to open whilst still maintaining the water barrier. Sure-Stop “RGW” For use in construction and contraction joints, this profile has a central web that facilitates shutter location. Fixing Sure-Stop “RG “ It is important that all waterstops are held securely during the concrete pour and that the concrete is properly compacted to remove voids and porous areas. For horizontal applications where an already stable support exists, Sure-Stop “RG” profiles generally require no fixing as they are laid centrally along the joint being formed. For vertical applications Sure-Stop “RG” profiles can be nailed through the outer flanges directly onto the formwork. Intersections A range of prefabricated intersections, both standard and specials are available for each Sure-Stop profile. These are made in our factory and are usually very difficult to make in the field. By using factory-made intersections, the contractor has to only make straight joining welds on site. The standard leg length is 250 mm. Factory welded units to suit lift pits, etc. are also available. Page 2 559
