Dual Seal waterproofing membrane has been specifically developed for use as a high performance waterproofing membrane to provide a totally watertight barrier in below ground concrete construction, including basements, underground car parks, plant rooms, access tunnels etc.
Dual Seal Membrane can be installed in damp conditions and is, therefore, particularly suitable for use as a roof waterproofing system for earth covered potable water reservoirs.
