High quality Visqueen Gas Venting System products

What is the Visqueen Gas Venting System?

The Visqueen Gas Venting System, including the Visqueen Gas Vent Mat is designed to create a 25mm deep void beneath reinforced concrete ground floor slabs.

Hazardous ground gases or volatile organic compounds (VOCs) are collected within the void and dispersed to atmosphere via a designed arrangement of Visqueen connectors and venting components, collectively managing and effectively diluting the collected gases.

The mat itself is constructed from durable, permeable materials that allow gas to escape while providing a protective barrier against moisture and other contaminants.

How Is The Gas Venting System Installed?

Where high gas concentrations have been recorded the vent mat can be laid in a blanket format with the individual mats being butted together. Where the gas concentrations are low or where pressure relief is required the vent mat can be laid in a strip format with the mat being laid at predetermined spacings.
