1. Cementitious Waterproofing
Made from cement-based compounds mixed with waterproofing additives.
Easy to apply (brush or trowel).
Common in bathrooms, toilets, and water tanks.
Rigid system (not flexible for cracks).
2. Liquid Waterproofing Membrane
A liquid coating (usually polymer-based) that cures to form a rubber-like membrane.
Applied by roller, brush, or spray.
Flexible and seamless.
Used on roofs, balconies, and wet areas.
3. Bituminous Waterproofing
Uses bitumen (asphalt-based materials).
Two main forms:
Bituminous membrane (torch-applied rolls)
Bituminous coating
Common for foundations and low-slope roofs.
4. Bituminous Membrane Waterproofing
Pre-fabricated sheets.
Applied using heat (torch) or self-adhesive backing.
Strong and durable.
Used for basements and flat roofs.
5. Polyurethane Waterproofing
Highly flexible liquid membrane.
Excellent crack-bridging ability.
Used for exposed roofs and terraces.
Requires dry surface during application.
6. EPDM Rubber Waterproofing
Synthetic rubber membrane.
Highly durable and weather resistant.
Common for large commercial flat roofs.
7. PVC Waterproofing Membrane
Single-ply membrane system.
UV resistant.
Used in commercial roofing systems.
8. Crystalline Waterproofing
Chemical treatment that reacts with concrete.
Forms crystals that block water paths.
Used for basements, water tanks, and foundations.
