Hydrostop 150mm PVC Centre-Stop Waterstop

PVC waterstops have been used for many years and are still considered one of the best forms of waterstop. The PVC extrusion creates a tough, watertight barrier between the concrete joints and prevents the ingress of water through the joint.
Centre-stop waterstop needs to be located centrally in the concrete and is typically tied to reinforcing bars. A welding iron is required to weld the two ends together should the waterstop need to be joined. Factory-made intersection pieces are also available to make site installation easier.
PVC Centre-Stop features a centre-bulb, and is designed specifically for expansion joints. The centre-bulb will compress or stretch as the joint moves without compromising the waterstop.
