ITP has launched Powerbase Gas NF, a new non-foil gas barrier membrane developed to expand its range of ground gas protection solutions for brownfield and contaminated land applications.
The latest addition to ITP’s Powerbase geomembrane range, Powerbase Gas NF has been developed in line with current industry guidance and modern best practice by eliminating the aluminium foil layers traditionally found in many gas membranes, which can be prone to corrosion. Supplied in practical 2m x 30m rolls, the membrane has been independently tested to ISO EN15105-1 permeation test methods for protection against methane, radon and CO₂.
Paul Harrison, Head of ITP’s Gas Barrier Team, said:
“Powerbase Gas NF represents another important step forward in membrane. Conventional foil-based gas membranes have long provided effective resistance against methane, CO₂ and radon gases, but industry understanding has evolved regarding the potential risks associated with aluminium foil layers when placed in contact with wet concrete or screed.”
