Aqueous Bitumen


A bitumen and rubber latex emulsion applied cold as a horizontal damp-proof membrane in solid laid concrete floors and can also be used as a vertical membrane on the positive (external) side of a structure. However, for tanking on the negative (internal) side, or where hydrostatic pressure is involved, it is recommended Sovereign Hey'di K11 Tanking System is used.

When dry the material forms a black, tough, resilient, waterproof coating.

Complies with the British Standard Code of Practice CP 102:1973: Protection of buildings against water from the ground, Sections 1005 and 1007.
