Waterstops Overview

An element of a concrete structure, intended to provide water tightness when embedded in and running through concrete joints. Waterstops are frequently manufactured from extruded plastics such as: PVC or thermoplastic elastomeric rubber (TPER),or extruded thermosets such as: natural rubber, styrene butadiene rubber, or neoprene rubber.

PVC waterstops cast into and across in-situ concrete joints to prevent ingress of or loss of water through joints in water retaining or water excluding structures.The product is centrally placed for both construction and expansion joints.

Typical use areas include joints between old to new concrete, where the designed waterstop has been forgotten or omitted, or in difficult bends and angles where the flat profile of a PVC waterstop cannot work.
