Features & benefits

• Large format rolls - rapid installation

Usage

• Visqueen Gas Vent Mat is designed to create a 25mm deep void beneath reinforced concrete ground foor 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 efectively diluting the collected gases.
• 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.
