Visqueen Building Products launch new solution for high risk waterproofing applications

We have launched a new Pile Cap Sealer and Waterstops range which takes the complexity out of high risk below ground waterproofing applications.


The Pile Cap Sealer and Waterstops range is our new below ground waterproofing solution for high risk cast concrete applications; it works in conjunction with Visqueen Pre Applied Membrane (PAM) and forms part of our complete structural waterproofing solution, in accordance with BS8102:2009 regulations.

The Visqueen Pile Cap Sealer contains active chemicals which, when applied to a concrete surfaces react with the free lime and moisture within the concrete to form in depth, insoluble crystals which fill and block all capillaries, fissures, pores and minor cracks within the concrete. This effectively makes the concrete watertight for the lifetime of the structure.

Visqueen’s triangular VX90 Waterstop provides the ultimate watertight seal around the perimeter of the pile cap. This is a specially formulated sodium bentonite hydrophilic waterstop designed as an active reinforcement strip at internal 90° angles – changes of direction – and to seal around pile cap penetrations. The unique properties allow this high performance waterstop to swell in all directions of the water, acting as a barrier, unlike other waterstops which only swell in a uniform direction. It also contains a special additive that delays the swelling process. This greatly assists installation times during periods of rain.

The Visqueen VX25 Waterstop is the same formulation but is square in shape and is designed to prevent the ingress of water through in-situ cast concrete construction joints.

• Simple on-site mixing method
• Quick and easy to apply
• Ensures a watertight seal for the lifetime of the building
