anking Slurry 20kg is a high-performance cementitious waterproofing compound designed to stop water ingress and protect masonry, concrete, and brickwork from damp. Easy to apply by brush, roller, or spray, it forms a dense, durable coating that resists both positive and negative water pressure, making it ideal for basements, cellars, foundations, retaining walls, and other below-ground structures.

This professional-grade waterproofing slurry is suitable for both internal and external use and can be applied to a wide range of surfaces including blockwork, render, and concrete floors. Once mixed with clean water, it creates a smooth slurry that bonds directly to the substrate, sealing pores and cracks to create a long-lasting barrier against water and moisture.

Key Benefits:

  • Effective damp proofing solution – stops water penetration and protects against rising damp.

  • Versatile application – suitable for walls, floors, foundations, water tanks, swimming pools, and retaining structures.

  • Durable protection – forms a strong, cement-based barrier that withstands high water pressure.

  • High adhesion – bonds securely to brick, block, and concrete substrates.

  • Internal and external use – can be applied above or below ground for complete waterproofing.

  • Professional results – widely used by builders, contractors, and DIY renovators for long-term damp control.

Typical Uses:

  • Waterproofing basements and cellars to keep living spaces dry.

  • Lining and sealing concrete or masonry water tanks, ponds, and pools.

  • Creating a damp proof barrier on foundations, retaining walls, and garden structures.

  • Renovating damp-affected masonry in homes, garages, and outbuildings.

  • Providing a protective waterproof coating on walls and floors prior to finishing.

  • Coverage: approximately 6–8 m² per pack, depending on surface porosity and thickness applied.
