Volclay® Waterproofing System

The Volclay® Waterproofing System consists of products that are based on or use sodium bentonite as the principal waterproofing component. The system is used as a damp-proofing or waterproofing membrane below ground to protect basements and other underground structures against water penetration and water vapour transmission from the ground. The system is also used to waterproof decks where they act as a roof to spaces below.

The system is based on two membranes, Voltex® and Swelltite®, with other accessory products completing the system.
