Z-Led has developed Protect GDB10 Gas and Damp Barrier which both stops methane, carbon dioxide and radon from entering a building and also provides a damp-proof membrane

When installed with Z-Led’s Cavity and Slab Edge Protection System, the GDB10 Barrier provides a barrier for protection of buildings against both gas and damp. When used as an oversite membrane below floor slabs or suspended floors, it provides a complete solution in compliance with Building Regulations Part C and BRE Report BR 414 2001: Construction of buildings on gas contaminated land, without any need to install an additional damp proof membrane.
