Composite EVA Geomembrane with Geotextile Backing for Drainage & Protection
Classification :
PRODUCT DETAILS
1. Product Overview
Waterproofing + Protection + Drainage in One Roll. Our Composite EVA Geomembrane combines the superior impermeability of EVA resin with a protective layer of Non-woven Geotextile (typically 200g-400g/m²). This innovative dual-layer design serves multiple functions: the EVA sheet prevents water ingress, while the geotextile backing cushions the liner against sharp rocks on the substrate and facilitates the drainage of groundwater to side drains.
2. Key Features
Built-in Puncture Protection: The geotextile layer acts as a buffer, significantly reducing the risk of the EVA liner being punctured by sharp shotcrete or rebar during installation.
Integrated Drainage Path: The geotextile creates a transmissive layer that allows hydrostatic pressure to dissipate, preventing water buildup behind the liner.
Installation Efficiency: Installing a composite roll is 50% faster than laying geotextile and geomembrane separately.
Enhanced Friction: The rough geotextile surface increases friction against the civil structure, preventing slippage during placement.

PROJECT CASES
APPLICATION AREAS
Geotechnical material series are widely used in various fields such as highways, railways, tunnels, water conservancy of reservoirs and canals, artificial lakes, environmental protection, sewage treatment, landfills, anti-seepage of tailings reservoir areas, and livestock breeding.
Water conservancy projects
Geosynthetics play a vital role in water conservancy projects such as dams and reservoirs, canals and channels, and riverbank protection.
Breeding industry
In the aquaculture industry, geosynthetics such as geomembranes and geotextiles can be used to create healthy aquaculture ponds, ensure stable water quality and reduce water resource consumption. All geosynthetics provided by can be customized according to customer needs.
Road construction
The geosynthetics such as geomembranes, geotextiles, geogrids, geocells, etc. provided by play an irreplaceable role from roadbed treatment to pavement protection, from drainage systems to environmental protection isolation.
Agricultural
In agricultural irrigation and biogas digester scenarios, geosynthetics such as geomembranes and geotextiles play a key role due to their respective characteristics. The products provided by Factory meet the standards and can be customized according to requirements.
Coastal Engineering
In coastal engineering, geosynthetics such as geobags, cement blankets, and geogrids play an important role in coastal engineering from coastal protection, structural reinforcement to slope stability, and effectively respond to the challenges brought by the complex geology and environment of coastal areas.
Environmental Protection
Factory provides customers with high-standard geosynthetics to meet their needs for building landfills.
