Fully Bonded SBS Waterproofing Membrane for Deep Foundations
–20°C Cold Flexibility | 100°C Heat Resistance (Minimum)
Sim Proof Membrane is a professional-grade, SBS-modified bituminous waterproofing membrane reinforced with high-strength polyester felt.
Developed with advanced modified bitumen technology, it is specifically designed to provide full and permanent adhesion to reinforced concrete during the hydration process of freshly poured concrete.
This unique bonding performance ensures a fully integrated waterproofing system.
Available Thicknesses:
- 3 mm
- 3.5 mm
- 4 mm
- 4.5 mm
FULLY BONDED WATERPROOFING SYSTEM
Sim Proof Membrane creates a complete mechanical and chemical bond with concrete.
By fully adhering to reinforced concrete structural elements, it:
- Prevents lateral water migration
- Eliminates water tracking behind the membrane
- Maintains adhesion even in case of ground settlement
- Prevents membrane separation from the foundation
This makes it ideal for high hydrostatic pressure environments.
KEY ADVANTAGES
- Permanent adhesion to fresh concrete
- Superior crack-bridging performance
- Resistant to ground movement
- High elasticity at low temperatures (–20°C)
- No need for protective concrete layer
- Reduces project cost and application time
- Suitable for single-sided waterproofing systems
NO PROTECTIVE CONCRETE REQUIRED
Unlike conventional systems, Sim Proof does not require an additional protective concrete layer.
This provides:
- Significant cost savings
- Faster project completion
- Reduced labor requirements
It is especially advantageous for projects where protective concrete cannot be applied.
FIELDS OF APPLICATION
Sim Proof Membrane is specifically designed for:
- Deep foundations
- Raft foundations
- Blind-side (single-sided) waterproofing applications
- Basement walls
- Below-grade reinforced concrete structures
- Inclined foundation surfaces
- Retaining walls cast against soil
It is an ideal solution for structures that remain permanently below ground level and are exposed to groundwater pressure.
WHY CHOOSE SIM PROOF?
- Eliminates water tracking risk
- Ensures long-term structural protection
- Designed for demanding underground projects
- High-performance solution for professional contractors
