Greenseal PVC Waterstop

Greenseal PVC Waterstops lead the way in high technology waterstops, combining 40 years of manufacturing know how to international standards. Greenseal Waterstops are extruded from specially compounded PVC in accordance with BS 2571 Class and ASTM 3 Type G3. They are designed for use in water retaining and water excluding structures where a positive seal is required for poured in-situ concrete expansion, contraction and construction joints.

The range of profiles for both centrally and externally placed applications when embedded into the concrete, form a continuous watertight barrier making Greenseal PVC Waterstops ideal for preventing water penetration. These profiles are available in rolls with separate intersections supplied to simplify and minimize in site fabrication.

Concrete structures are only as watertight as the waterstops that join them. Greenseal Waterstops are designed to allow for expansion, contraction and other movements that can cause joints to open and close.

The efficiency of any waterstops is very independent on good workmanship and on full compaction of the surrounding concrete. Optimum performance will be achieved if the waterstop is installed by keeping these factors in mind.
