PVC Waterstop
Permeseal PVC Waterstop is a product made from virgin PVC designed for use in concrete construction containing joints, one side of which is subject to hydrostatic pressure. The waterstop is used as a barrier within the joint to prevent the passage of liquid through or across the joint. It is embedded in the concrete on both sides of the joint, spanning the joint. It is designed to accommodate lateral and transverse movements that cause the joints to open or close or misalign. WRAS – Approved Msterial.
This material is specially designed to fulfill the requirements of the British Standard. It also meets the requirements of the Water Regulation Advisory Scheme (WRAS), Tests on Effect on Water Quality/BS 6920:2000/Cold Water use.
Some of the structures requiring waterstop include swimming pools, storage tanks, roof and floor slabs, parking decks, bridge decks and abutments, foundations, basements, retaining walls, dams, locks, sewage and water treatment plants, water reservoirs, canals, culverts, tunnels, elevator pits, and all concrete structures requiring tight joints.
