1. Product Overview

Styrene-Butadiene-Styrene (SBS) modified bitumen waterproof membrane is a premium waterproofing material made by modifying high-quality bitumen with SBS elastomer. It is reinforced with polyester felt or fiberglass to enhance tensile strength and dimensional stability. This membrane offers superior flexibility, excellent high-temperature resistance, and strong adhesion, making it ideal for roofing, underground waterproofing, and infrastructure projects.

2. Key Features

• Outstanding Flexibility: The SBS modification enhances elasticity, allowing the membrane to accommodate structural movements and prevent cracking.

• Superior Temperature Resistance: Maintains flexibility in low temperatures and resists deformation in high temperatures, ensuring long-term durability.

• High Tensile Strength: Reinforced with polyester or fiberglass, providing excellent mechanical strength and resistance to external forces.

• Strong Adhesion: Bonds securely to concrete, metal, wood, and other substrates, ensuring effective waterproofing performance.

• Aging and Weather Resistance: Excellent resistance to UV rays, ozone, and oxidation, extending the membrane’s lifespan.

• Versatile Application Methods: Can be installed using torch-applied, hot-melt, or self-adhesive methods to suit different project requirements.

3. Applications

• Waterproofing for industrial, commercial, and residential building roofs.

• Underground waterproofing for basements, tunnels, and subways.

• Protection for bridges, highways, and railways.

• Waterproofing for reservoirs, water treatment plants, and other water retention structures.

4. Installation Process

1. Surface Preparation: Ensure the substrate is clean, dry, and free of dust, grease, or loose particles.

2. Primer Application: Apply a bitumen-based primer to improve adhesion between the membrane and the substrate.

3. Membrane Installation:

• Torch-Applied Method: Use a propane torch to heat the membrane’s underside while unrolling it onto the surface.

• Hot-Melt Method: Apply hot bitumen adhesive before laying the membrane.

• Self-Adhesive Method: Remove the release film and press the membrane onto the prepared substrate.

4. Seam Treatment: Overlap adjacent membranes and heat-weld or adhere them to create a seamless waterproofing layer.

5. Quality Inspection: Conduct adhesion and waterproofing tests to ensure proper installation and long-term durability.
