Corrostop PVC

Description

PVC water stops for construction & expansion joints in concrete

Features

The Corrostop PVC plasticized water stop range are extruded high grade PVC profiles designed to be cast into construction or expansion joints to prevent the passage of liquids under pressure. They work by creating a tortuous path with their profile, making it harder for liquids to travel across the joint and penetrate into the structure.

Additionally the shape of the bulbs along the profiles act like valves particularly during drying shrinkage, thus forming a tight seal that prevents the passage of liquids.

Corrostop PVC water stops are available in various widths and profiles, and are selected according to the type of structure and application they are to be used in.
Corrostop CJC – centrally placed waterstop for construction joints only
Corrostop CJE – centrally placed waterstop for expansion joints
Corrostop RJC – externally placed waterstop for construction joints only
Corrostop RJE – externally placed waterstop for expansion joints

Complies to BS 2571 and CRD – C 572 – 74.

Uses

Corrostop PVC is typically used on below ground, water retaining or water excluding structures such as basements, tunnels, culverts, manholes, pumping stations etc.

A guideline to the choice of profile and width to be used is given as follows:

The general rule of thumb is that for wall or slab thicknesses of 250 mm & above use a 250 mm wide waterstop profile. For widths less than 250 mm, use either 150 mm or 200 mm profiles to match as near as possible the thickness of the wall or slab.

External waterstops are generally used when there is positive water pressure directly on the waterstop, particularly in water excluding structures such as basements, tunnels etc. But are also used in base slabs in water retaining structures.

Centrally placed waterstops are always used in wall joints in water retaining structures, and can also be used in roof & podium deck joints or wall joints in water excluding structures.
