What is KA Tanking Slurry?
KA Tanking Slurry is a cement-based waterproofing system designed to stop water leakage, seepage and damp penetration in concrete structures or any cementitious substrate. When mixed with water, it forms insoluble crystals that grow into capillaries and fissures, blocking water pathways and ensuring permanent watertightness.
Key Benefits
- Permanent waterproofing through crystalline growth
- Works on new or old structurally sound surfaces
- Suitable for positive and negative side waterproofing
- Effective even under hydrostatic pressure
- Used with KA Super Plug for instant leak stopping
- Internal & external use
- Long-term protection for the life of the structure
