PVC waterbar or waterstop, a flexible material used to seal construction and expansion joints in concrete structures.
Function: It creates a watertight diaphragm within concrete to prevent water ingress, essential for structures like basements, tunnels, dams, and swimming pools.
Material: Typically made from plasticized polyvinyl chloride (PVC-P), providing high tensile strength, elongation, and permanent flexibility.
Availability: Available in various profiles (like V-shaped or O-shaped) and sizes to suit different joint types and hydrostatic pressure levels.
Installation: Supplied in rolls for placement directly into formwork during the concrete pouring process.
