URBAN SEAL WATERPROOFING
Interior & Exterior Waterproofing
Comprehensive waterproofing requires a dual-envelope defense: sealing positive-side exterior facades exposed to rain and wind, while treating negative-side interior surfaces affected by rising dampness or internal wet-area seepage.
Our Interior & Exterior Solutions
- Exterior Facade Protection: Spraying high-performance transparent silicone/silane water-repellents on exposed brick and stone, or applying elastic acrylic emulsions to masonry.
- Interior Damp Seepage treatment: Stripping saltpetre-infected plaster, applying high-penetration chemical moisture barriers, and rendering with waterproof plaster additives.
- Positive & Negative Defenses: Providing robust polyurethane barriers to block water ingress at its source, and cementitious barriers to resist internal back-pressure dampness.
