Cementitious Waterproofing Slurry for Concrete & Masonry
Price range: R202.17 through R418.31
Waterproofing slurry is a cement-based waterproof coating designed to protect concrete, masonry and cementitious surfaces from water penetration. When applied correctly, it forms a durable waterproof barrier that helps prevent moisture ingress, dampness and water-related structural deterioration.
Waterproofing slurries are widely used in commercial, industrial and residential construction projects because they bond directly to mineral substrates and become an integral part of the surface.
Unlike many surface-applied waterproof coatings, cementitious waterproofing slurries provide excellent adhesion to concrete and masonry while allowing long-term protection against water pressure and moisture intrusion.
These systems are commonly specified for basements, retaining walls, water tanks, lift pits, swimming pools, bathrooms and below-grade structures where moisture protection is critical.
| Code | Description | Units |
|---|---|---|
| 210/02/020 | WATERPROOFING-SLURRY™ | 1 Litre |
| 210/02/050 | WATERPROOFING-SLURRY™ | 5 Litre |
Waterproofing slurry is a cementitious coating consisting of specialised cements, graded aggregates and waterproofing additives. When mixed with water or liquid polymer additives, it creates a brushable or trowel-applied waterproof barrier.
Once cured, the slurry forms a dense waterproof layer that reduces water penetration while maintaining strong adhesion to concrete, masonry and cement-based substrates.

What is waterproofing slurry?
Waterproofing slurry is a cementitious coating used to prevent water penetration through concrete and masonry surfaces.
How does waterproofing slurry work?
It bonds to the substrate and forms a dense waterproof barrier that reduces moisture penetration.
Can waterproofing slurry stop leaks?
Yes. When correctly applied to suitable substrates, it can help prevent water ingress and leakage.
Can waterproofing slurry be used on retaining walls?
Yes. It is commonly used on retaining walls and below-grade structures.
Can it be used on concrete water tanks?
Yes. Cementitious waterproofing systems are widely used for water-retaining structures.
What is the difference between waterproofing slurry and waterproof membrane?
Waterproofing slurry is cement-based and bonds directly to concrete, while membranes are typically polymer-based surface systems.
Can waterproofing slurry be applied to damp concrete?
Many cementitious systems can be applied to damp substrates, subject to manufacturer instructions.
How long does waterproofing slurry last?
When correctly installed and maintained, cementitious waterproofing systems can provide long-term protection for many years.
