Product Description

Powerbase MultiGas 300 is a multilayer gas barrier membrane constructed from reinforced low-density polyethylene that will protect converted brownfield sites from radon, methane and CO2. This geosynthetic gas barrier membrane can be used in applications for groundwater or environmental protection installations as it will protect against naturally occurring hazardous gases as well as contaminated soils. 

The function of Powerbase MultiGas 300 barrier membrane is to prevent hazardous gases from permeating through the buildings above, protecting the occupants and the structural integrity. It is noted that you must take into consideration the mobility of hydrocarbons and any volatile organic compounds and assess the use of this gas barrier membrane. 

Highly resistance to tears and impact, Powerbase MultiGas 300 is supplied in 1.6m x 50m rolls which can be joined up on site using Powerbase’s sealing tape to create a larger cover area. 

Tested independently to ISO 15105-1 and BS 8485:2015, Powerbase MultiGas 300 can be used as damp-proof membrane and could be considered for tanking applications too. For tanking please contact us on 01752 692 221 for more information.
