Polyurethane-based membranes offer high elasticity and durability, making them a premium choice for foundation waterproofing.
Highlights
- Excellent UV resistance
- Superior crack bridging ability
- Long service life
6. Self-Adhesive Bituminous Membranes
Bituminous sheets are widely used for foundation waterproofing, offering a reliable, proven solution.
Why Choose Bituminous Membranes
- Strong adhesion to substrate
- Resistant to soil chemicals
- Cost-effective for large projects
7. Crystalline Waterproofing Admixtures
These admixtures are added to concrete to form crystals within the capillaries, blocking water ingress permanently.
Advantages
- Integral waterproofing solution
- Increases concrete durability
- Reduces maintenance needs
8. Spray-Applied Elastomeric Systems
Elastomeric systems provide quick application and a uniform membrane layer that adheres to irregular surfaces.
Benefits
- Rapid application saves labor cost
- Seamless and flexible
