Description

When protecting your property from the threat of radon or methane gas, this gas barrier has got you covered. Radon is often found in granite formations, while methane and CO2 are byproducts of organic matter decomposition, resulting from made ground or natural deposits of silt, peat or coal. This barrier is a must-have for brownfield developments, effectively preventing harmful gases, hydrocarbons and volatile organic compounds (VOCs) from infiltrating your building.

Features & Benefits: Powerbase Low Perm 500mu Gas Barrier Membrane - 12.5m x 4m

For protection against hazardous gases and contaminated soils
Ideal for areas with the risk of radon or methane gas
Perfect for areas found over granite formations, locations with decomposing organic matter and brownfield sites
Prevents harmful gases, hydrocarbons and VOCs from entering buildings
Designed to create an impermeable shield in the building's foundations over a ventilation layer
Supplied in a 4m x 12.5m roll with a 500-micron thickness
Thermally hot air weldable for optimum joint seal
Can be taped using Powerbond double-sided butyl tape and Powerbond single-sided foil tape

This gas barrier membrane is designed to create an impermeable shield in your building's foundations, complete with a ventilation layer. Harmful gases and VOCs naturally rise through the soil and collect under the membrane, where they are safely dispersed into the atmosphere. The primary role of this gas barrier membrane is to keep these harmful substances from entering your building through cracks, construction joints or service openings in the floor slab.

For comprehensive protection, make sure the membrane covers the entire plan area of your structure, including all external faces, cavity walls and voids. In cases of contamination by hydrocarbons or VOCs, it is essential to choose suitable materials, as these compounds can migrate through unsuitable barriers. The Powerbase® range offers task-specific engineered barriers and accessories that provide effective solutions for consultants and design engineers and cost-effective installation for contractors.

Standards & Certification

2000-gauge barrier membrane: BBA certified for radon, low-level methane and CO2
Independently tested: to ISO 15105-1 manometric test for methane and CO2
Permeation performance data: Conforms with BRE 414

Please note:

Aluminium laminates are excellent gas barriers but will delaminate when exposed to hydrocarbon vapour/VOCs and are susceptible to oxidation due to moisture penetrating into exposed edges.
