Sovereign Hey'di K11 Tanking Slurry

Sovereign Hey’di K11 is a salt-resistant cementitious tanking compound for the protection of structures against water from the ground, and which may be subject to hydrostatic pressure. It can be used on the external side of buildings below ground level where positive pressure exists or on the internal (negative) side without the need to build supporting walls. The Sovereign Hey’di tanking system is fully covered by the British Board of Agreement Certificate 91/2608. Once cured, K11 is impervious to water, and the system has been independently tested to withstand greater than 10 bars of pressure on the negative side (over 100 metres head of water) with a coating thickness of 4 mm in two coats.
