GCP Bituthene GP is an entry-level post-applied waterproofing membrane for low-risk below-ground situations such as single-skin basement walls and simple tanking details where hydrostatic pressure is minimal. Its self-adhesive rubber/bitumen compound bonds directly to primed concrete and masonry substrates, with adjacent rolls overlapped a minimum of 50mm and firmly rolled to ensure continuity. Bituthene LM liquid membrane is applied at all corners and penetrations prior to laying the sheet. Benefits Cold applied, self-adhesive, no flame, no heating, no torch-on equipment Resists up to 1m hydrostatic head when fully supported Resistant to most dilute acids and alkalis Flexible accommodates minor settlement and shrinkage movement Good to know BBA certified Protection 03 board must be used immediately to protect the membrane from damage by other trades, backfill or construction materials. Minimum application temperature: +5°C Typical applications include; external waterproofing of basement walls and foundations, below-ground concrete and masonry structures with up to 1m hydrostatic head and cold-applied post-applied tanking on clean, dry, primed substrates
