Gas Membrane

MacLennan design and install gas-proof basement waterproofing systems through installation of external-applied gas membrane systems, internal liquid roller or spray-applied gas membrane and radon barrier.

If you are building a basement, you are required to carry out site investigations that involves inspection for ground gases.

MacLennan together with our partners provides combined solutions for both waterproofing and gas protection.

The provision of a waterproof membrane to the outside of the basement of substructure in accordance with BS8102:2009 (‘Type A’ form of construction) can also be a gas membrane and external tanking, and waterproofing can be combined where required.

Internal cavity drain membrane systems can be detailed as gas membranes/Radon barriers when married up with suitable extraction or positive pressure systems.
