Product Description:

Weidun® 008 EVA Waterproofing Membrane is a high-quality geotechnical composite material made from Ethylene-Vinyl Acetate copolymer. Designed for durability and flexibility, this membrane offers excellent waterproofing, puncture resistance, and chemical stability.

Uses：

This versatile membrane is engineered for a wide range of applications, including but not limited to:

Tunnel Engineering: Primary and secondary lining waterproofing for railways, highways, and subways.

Underground Construction: Basements, sub-basements, and retaining wall protection.

Landfill & Waste Containment: Protective lining to prevent leachate contamination.

Infrastructure: Bridge deck waterproofing and culvert linings.

Mining: Heap leach pads and tailings storage facilities.

Product Advantages

High Flexibility & Elongation: The EVA formulation maintains excellent flexibility at low temperatures, allowing it to conform to irregular surfaces and accommodate structural settlement or cracking without tearing.

Superior Chemical Resistance: Exhibits strong resistance to acids, alkalis, oil, and microbial corrosion, ensuring long-term performance in aggressive soil and water environments.

Excellent Physical Properties: Features high tensile strength and puncture resistance, providing a robust barrier against sharp aggregates and construction stress.

Environmentally Friendly: Non-toxic and free from volatile components, making it safe for use in potable water applications.

Ease of Installation: Lightweight and flexible, it is easy to handle and install. Compatible with hot-wedge and extrusion welding techniques for secure, watertight seams.

 Storage and Handling:

 Store in a clean, dry, and level area away from sharp objects that could puncture the material.

 Store in a cool, well-ventilated area. Avoid exposure to open flames or high-temperature environments.

 Keep away from solvents, fuels, grease, and extreme heat sources.
