K11 is a salt resistant cementitious tanking compound for the protection of structures against water from the ground and which may potentially be subject to hydrostatic pressure. K11 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. 
 
K11 Grey must always be used as the first applied coating, K11 White can only be used as a secondary coating. Used in conjunction with SBR Bonding Agent
 
The Sovereign Tanking system is fully covered by British Board of Agrėment Certificate 91/2608.
