Volclay Voltex Suitable for Harsh Weather Conditions

Voltex is a highly effective waterproofing composite of high strength geotextiles.

Installation of Voltex is fast and easy — simply position the product into place and fasten. Voltex can be installed on green concrete, is designed for use in the basement environment (wet and dirty) and is able to be installed in virtually any weather, without the need for primers or adhesives.

Voltex can be easily cut on site to form around corners and penetrations. The result is always a consistent self-healing membrane.
