PRODUCT DETAILS
1. Product Overview
The Premium Anti-Puncture Solution for Rough Substrates.
When the substrate is extremely rough (e.g., exposed shotcrete, sharp aggregate, or rebar ends), a standard liner will fail. Our Heavy-Duty EVA Composite Geomembrane utilizes the rubber-like flexibility of EVA, known for its superior anti-stress cracking properties, and combines it with heavyweight nonwoven geotextile (300g/m² to 800g/m²). This combination creates an almost impenetrable barrier, specifically designed for tunnel lining, deep basement walls, and structures requiring maximum long-term protection against environmental damage.
2. Key Features
-
Maximum Cushioning: Heavy-duty geotextile provides maximum padding, essential for protecting the geomembrane against sharp, protruding shotcrete surfaces common in tunnel construction.
-
High Resistance to Structural Stress: EVA material maintains high elongation and strength even under confinement, reducing the risk of liner damage caused by construction activities or minor structural shifts.
-
Superior Welding for Tunnels: EVA is easier to weld in overhead or difficult positions than polyethylenes, making installation faster and safer in confined spaces.
-
PVC-Free: Eco-friendly alternative to PVC, ensuring no plasticizer migration and a long, stable service life in underground water sources.
3. Applications
-
Tunnel Lining: Protecting the waterproofing layer from rough primary lining materials.
-
Deep Basement Walls: Waterproofing against high hydrostatic pressure and rocky backfill.
-
Mining Pads: Use as a secondary liner with high cushioning where extreme loads are applied.
