Cementitious Waterproofing
One of the most widely used waterproofing systems — a cement-based coating that bonds directly to concrete and masonry.
What it is
Cementitious waterproofing is a factory-blended mix of cement, fine aggregates and polymer additives, applied as a coating that bonds mechanically and chemically to the substrate. It forms a rigid, durable barrier and is one of the most common systems used in bathrooms, water tanks and general masonry waterproofing.
How it works
The mix is applied in two or more coats directly onto a clean, prepared concrete or masonry surface, typically by brush or trowel. Once cured, it forms a hard, adherent layer that resists water penetration while remaining breathable enough for the substrate underneath.
When it's used
- Bathroom and wet area waterproofing beneath tile flooring
- Water tanks, sumps and other masonry water-retaining structures
- General masonry and plastered surfaces where rigid, non-flexible coverage is appropriate
Advantages
- Straightforward to apply and cost-effective for many standard applications
- Bonds well to both concrete and masonry surfaces
- Widely available and well understood, with a long track record of use
