※  Material Features

• 
  

• Superior Flexibility and Elongation: The EPDM layer offers exceptional elasticity, allowing the membrane to stretch and adapt to substrate movements without compromising the waterproofing seal. This makes it ideal for structures prone to expansion, contraction, or shifting.

• Self-Adhesive Application: The self-adhesive asphalt layer ensures a quick, clean, and easy installation process. Simply peel off the protective film and apply the membrane to the prepared surface, saving time and labor costs while reducing installation complexity.

• Strong Adhesion to Various Surfaces: Thanks to the asphalt adhesive backing, this membrane bonds effectively to a wide range of substrates, including concrete, wood, metal, and insulation boards, making it a versatile solution for different types of structures.

• Exceptional Water and Vapor Barrier: The EPDM layer, combined with asphalt, creates a robust waterproof barrier that prevents water infiltration and vapor transmission. This ensures protection against leaks and moisture damage in both above-ground and below-ground applications.

• Weather and UV Resistance: The membrane is designed to withstand harsh environmental conditions, including UV exposure, extreme temperatures, and weather fluctuations, without degrading or losing its waterproofing efficiency.

• Chemical Resistance: It offers excellent resistance to various chemicals, acids, and alkalis, ensuring that the membrane remains effective even in industrial or chemically-exposed environments.

※  Application

• Roofing Systems: Ideal for flat or low-slope roofs, the EPDM Asphalt Self-Adhesive Waterproofing Membrane provides a seamless and durable waterproofing layer, preventing leaks and ensuring long-lasting protection against weather elements.

• Basement and Foundation Waterproofing: This membrane serves as a highly effective waterproof barrier for basements, foundations, and retaining walls, protecting underground structures from water ingress and soil moisture.

• Bridges and Tunnels: The combination of EPDM and asphalt offers high tensile strength and flexibility, making it suitable for critical infrastructure projects like bridges, tunnels, and subways.

• Balconies and Terraces: The self-adhesive membrane is perfect for waterproofing terraces and balconies, where complex shapes and structures require a flexible yet reliable waterproofing solution.

Installation Process

1. Surface Preparation: Ensure the surface is clean, dry, and free of dust, oil, or sharp objects that could damage the membrane.

2. Priming (if necessary): In certain cases, a primer may be applied to improve adhesion on porous or uneven surfaces.

3. Membrane Placement: Roll out the membrane and allow it to settle for proper alignment. Peel back the protective film and press the membrane firmly onto the substrate.

4. Sealing Seams: Overlap adjacent sheets by 50-100 mm, and press firmly to ensure a strong seal at the seams. Use a roller to eliminate air bubbles and ensure full contact.

5. Edge Treatment: Ensure all edges and terminations are securely fastened and sealed to prevent water infiltration.

Benefits of Using Our EPDM Asphalt Self-Adhesive Waterproofing Membrane

• Time-Saving Installation: The self-adhesive design eliminates the need for additional adhesives, heating, or mechanical fasteners, significantly speeding up the installation process.

• Cost-Efficiency: Reduced labor costs, minimal tools required, and long-term durability make this membrane a cost-effective choice for waterproofing projects.

• Eco-Friendly: The EPDM material is fully recyclable, contributing to sustainable building practices and reducing environmental impact.

• Long-Term Durability: With its excellent resistance to weather, UV rays, and chemicals, the membrane provides decades of reliable waterproofing protection.

※  Storage and Transport

Storage Guidelines

1. Cool, Dry, and Shaded Storage: Store the membrane in a cool, dry, and shaded area, away from direct sunlight, moisture, or rain. Extended exposure to UV light or extreme weather conditions can cause the adhesive to lose its tackiness and reduce the elasticity of the EPDM layer.

2. Temperature Range: Ensure that the storage temperature is maintained between 5°C to 30°C. Prolonged exposure to temperatures outside this range can negatively impact the membrane’s adhesive properties and flexibility, making it harder to apply and more prone to cracking or deformation during installation.

3. Vertical or Horizontal Roll Storage: When storing, keep the membrane rolls standing vertically on a flat surface to prevent deformation, especially in warmer environments. If stacked horizontally, ensure that no more than three rolls are placed on top of each other to avoid excess pressure on the lower rolls, which could cause flattening or creases.

4. Protect from Physical Damage: The storage area should be free from sharp objects, heavy machinery, or any items that could puncture or tear the membrane. Keep the rolls in their original packaging until ready for use to prevent contamination with dust, debris, or moisture.

5. Humidity Control: High humidity can affect the adhesion of the asphalt layer. It’s important to store the membrane in a well-ventilated area with controlled humidity levels, ideally below 60%, to maintain the adhesive’s effectiveness.

Transport Guidelines

1. Secure Packaging: During transport, the EPDM Asphalt Self-Adhesive Waterproofing Membrane should remain in its original packaging to protect it from dust, dirt, and moisture. Ensure the packaging is tightly sealed, especially if transporting in open-air vehicles, to prevent exposure to the elements.

2. Proper Loading and Stacking: During loading, avoid stacking rolls too high or applying excess pressure, as this can cause deformation or damage to the membrane. Ensure that the rolls are placed securely and uniformly on the vehicle to avoid movement or rolling during transit.

3. Protection from Heat and Sunlight: When transporting over long distances, especially in hot climates, make sure the membrane is covered and shielded from direct sunlight or heat. Prolonged exposure to high temperatures during transport can compromise the adhesive layer, reducing its effectiveness upon installation.

4. Gentle Handling: Handle the membrane rolls with care when loading and unloading to avoid tearing or puncturing the surface. Avoid dragging the rolls across rough surfaces or dropping them, which could damage the EPDM or adhesive layers.

5. Inspection Upon Delivery: Once the membrane arrives at its destination, inspect the rolls for any signs of damage during transit, such as punctures, creases, or tears. Any damaged sections should be marked and not used, ensuring that only high-quality material is applied during installation.
