1. Product Overview

The self-adhesive polymer-modified bitumen waterproof membrane is an advanced waterproofing material composed of high-quality modified bitumen, reinforced with polyester felt or fiberglass. It features a self-adhesive layer covered with a release film, eliminating the need for heating or open flames during installation. This membrane provides excellent waterproofing performance, superior flexibility, and strong adhesion, making it ideal for a variety of roofing and underground waterproofing applications.

2. Key Features

• Self-Adhesive Application: Easy and safe installation without the need for heating, reducing fire hazards and labor costs.

• Superior Waterproofing Performance: Ensures complete water resistance, preventing leaks and moisture infiltration.

• High Flexibility and Elongation: Adapts to structural movements and prevents cracking.

• Excellent Adhesion: Strong bonding to concrete, metal, wood, and other substrates for long-lasting protection.

• Aging and Weather Resistance: High resistance to UV rays, oxidation, and environmental aging, ensuring durability.

• Cold-Applied Technology: Suitable for low-temperature environments, maintaining flexibility and ease of application.

3. Applications

• Roofing waterproofing for residential, commercial, and industrial buildings.

• Underground waterproofing for basements, tunnels, and subways.

• Waterproofing for bridges, highways, and railway structures.

• Water retention structures such as reservoirs, dams, and water treatment plants.

4. Installation Process

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

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

3. Membrane Installation:

• Remove the release film from the self-adhesive layer.

• Align the membrane and carefully press it onto the prepared substrate.

• Use a roller to ensure proper adhesion and eliminate air bubbles.

4. Seam Treatment: Overlap adjacent membranes and firmly press them together to create a seamless waterproofing layer.

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