20kg Cement-Based Tanking Slurry for Cellar & Basement Waterproofing

Single-component, cement-based waterproofing slurry for cellars, basements and below-ground masonry.

A ready-to-use tanking coating formulated with Portland cement, graded aggregates and acrylic polymer modifiers. Applied by brush directly to damp surfaces, it cures to form a vapour-permeable yet watertight barrier that resists water pressure and prevents ingress in below-ground structures. Two coats are required for full protection.

Key Features

• Single-component, cement-based formulation
• Acrylic polymer enhancement for strength and adhesion
• Vapour-permeable yet watertight when cured
• Resists sustained water pressure
