GCP Bituthene GP Membrane

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
