ITP Powerbase® VOC is a multilayered barrier membrane which gives protection against naturally occurring hazardous gasses and soils contaminated with hydrocarbons or toxic industrial pollutants. ITP Powerbase® VOC can also used for groundwater and environmental protection installations.

ITP Powerbase® VOC is specifically designed for developments on brownfield or contaminated land which require effective gas barriers to prevent harmful gasses such as methane, radon and carbon dioxide CO₂ along with hydrocarbons and volatile organic compounds (VOCs) from permeating into buildings.

Brownfield sites can be land previously occupied by chemical and paint works, timber treatment, petrochemical plants and fuel stores, petrol stations, tanneries, paint factories, paper mills, coalfields, disposal and landfill sites.

HDPE and other homogenous membranes, many of which claim to be hydrocarbon resistant, are in fact permeable to certain toxic vapours and gasses and do not offer adequate protection. ITP Powerbase® VOC comprises protective polymeric layers on both sides of a hydrocarbon and chemical resistant inner core.

ITP Powerbase® VOC is supported by a unique software application, the ITP Powerbase® VOC app, a simple-to-use app which provides performance data for a wide range of harmful chemicals. This app is used by design and environmental engineers as part of the risk assessment and is available to download.

ITP Powerbase® VOC is complemented with a full range of top hats, corner pieces and tapes.
