URBAN SEAL WATERPROOFING
Brick Wall Waterproofing
Exposed brick masonry is highly porous and absorbs significant rainwater during heavy downpours. This capillary moisture leads to peeling wall paint, crumbling interior plaster, and white powder deposits (saltpetre efflorescence) inside your living areas.
Our Brick Wall Treatment Systems
- Exterior Hydrophobic Coatings: Applying high-grade siloxane water repellents that seal pores while maintaining concrete breathability, forcing rainwater to bead off.
- Anti-Saltpetre Primers: Stripping wet plaster, treating the bare bricks with acidic washes to extract mineral salts, and applying salt-blocking epoxy-acrylic primers.
- Chemical DPC Injection: Drilling into mortar joints and injecting silane-based cremes to create an internal horizontal barrier that blocks rising damp.
