Sovereign Heydi K11 Grey - 25K SLURRY30607678

Sovereign Hey'di K11 is a salt-resistant cementitious tanking compound designed to protect masonry structures from water ingress from the ground, particularly under hydrostatic pressure. It enables waterproofing without supporting walls on the internal side, making it ideal for basements and cellars.

Formulated as a blend of cement, Portland cement, additives, and flue dust, it forms an impervious barrier once cured. Independently tested to >10 bars pressure on negative side at 4mm thickness (two coats of 2mm min each), covered by BBA Certificate 91/2608.
