KA Tanking Slurry™ is a high‑performance cementitious waterproofing system engineered to permanently stop water ingress in concrete, masonry and blockwork structures. Using advanced crystalline technology, it penetrates deep into the substrate and forms insoluble crystals that block water‑bearing capillaries — delivering a durable, integral barrier against both positive and negative water pressure.

​

Designed for basements, lift pits, retaining walls, cellars, tunnels and all below‑ground environments, KA Tanking Slurry™ provides long‑term protection where structural waterproofing cannot fail. Manufactured in Cornwall and trusted by contractors across the UK, it delivers reliable performance, consistent coverage and professional‑grade results on every project.
