Waterstops – Hydrophilic


Dual Seal is manufactured from Sodium Bentonite which swells up to 20 times its dry volume in contact with water to provide a totally watertight joint.

It can be applied directly onto scabbled surfaces even in damp conditions prior to the next concrete pour. It requires no welding, adhesives or special junctions. Jointing and change of direction is simply achieved by overlapping by 50mm.

Adcor 500

A conformable, swellable polymer/butyl rubber waterstop strip that expands in contact with water. When fully encapsulated by poured concrete, the expansive forces form a seal against concrete faces. The seal resists hydrostatic pressure, stopping water from entering sub-structures. Adcor® is a unique product that has been specifically developed to provide higher performance than bentonite or conventional swellable rubber waterstops. Superior performance arises from:
• Controlled, reproducible, volumetric expansion.
• Cohesive strength maintained after volumetric expansion.
• Malleable and plastic, enabling easy application to a variety of concrete profiles.
