Product Description

Product Description

Waterproof Membrane For Roofing Underlayment

Roofing shingles and roofing sheets require waterproofing because their main function is to protect the building from water intrusion:
1. Prevent Leaks
Waterproof shingles and sheets stop rainwater from seeping into the building, preventing:
Ceiling and wall stains/Structural wood rot/Mold and mildew growth

2. Ensure Durability
Moisture damages roofing materials over time. Waterproofing extends the lifespan of both the roof and the underlying structure.

3. Maintain Insulation Efficiency
Wet insulation loses effectiveness, causing energy inefficiency. Waterproof roofing keeps insulation dry and functional.

4. Protect Interiors
A waterproof roof safeguards furniture, electronics, and personal belongings from water damage.

5. Comply with Building Codes
Most modern building standards and codes require roofing systems to be waterproof for safety and durability.

Polypropylene Waterproof Membrane

A Polypropylene Waterproof Membrane is a synthetic waterproofing sheet made from polypropylene (PP)—a type of thermoplastic.

Key Features
1:Flexible and tough: Handles structural movement and cracks.

2: Highly resistant to chemicals, mold, and UV (if stabilized).

3: Lightweight and easy to handle.

4: Often installed with cold adhesives or mechanical fixing, or embedded in mortar for tile installation.

SELF-ADHESIVE BITUMEN MEMBRANE

Self-Adhesive Bitumen Membrane is a type of waterproofing sheet made of bitumen (asphalt), modified with rubber-based polymer.

Self-adhesive: Comes with a sticky underside protected by a release liner. Just peel and stick.

Cold-applied: No open flames, heating, or heavy equipment required—ideal for sensitive or enclosed areas.

Flexible: Can conform to complex shapes and details.

Layered Structure: Top surface: Mineral, foil, or film (depending on use).

Core: Modified bitumen (often with SBS or APP).

SBS MODIFIED BITUMEN MEMBRANE

Elasticity: SBS gives the membrane rubber-like flexibility, allowing it to expand and contract with building movements or
temperature changes without cracking.

Waterproofing: Provides an excellent waterproof barrier, commonly used in flat roofs and below-grade waterproofing.

Durability: Resists aging, UV exposure (when protected), and environmental stress better than plain bitumen.

Installation methods: Can be applied by:
Torch-on (heat-welded)

Common Applications:
Commercial and residential flat or low-slope roofs
