EVA geomembrane
1. Flexibility and Crack Resistance
EVA geomembrane maintains excellent flexibility even in low-temperature environments, making it resistant to brittleness and cracking. It exhibits outstanding resistance to environmental stress cracking, is easy to handle during construction, and allows for reliable welding with minimal risk of damage.
2. High Strength and Tear Resistance
With high tensile strength, it can withstand punctures from sharp objects and external pressures such as soil compression. Its strong tear resistance provides dependable protection for engineering projects under challenging conditions.
EVA geomembrane is a geosynthetic impermeable material made from ethylene-vinyl acetate copolymer (EVA) through a multi-layer co-extrusion process. It is often laminated with geotextiles to form composite structures (e.g., "one fabric one membrane," "two fabrics one membrane"). The material features excellent aging resistance, puncture resistance, superior flexibility, and can withstand extreme temperatures ranging from -70°C to +70°C. It has a tensile strength of ≥14 MPa and an elongation at break of ≥400%. With outstanding weldability, it can accommodate uneven geological settlement. Available in thicknesses of 0.3–3 mm and widths of 1–6 m, the product complies with the Chinese standard GB/T 18173.1-2012.
Core Performance Advantages
1. Physical and Mechanical Properties: Exceptional flexibility, resistant to cracking at low temperatures, with high puncture and tear resistance, capable of withstanding sharp objects and soil compression.
2. Weather and Chemical Resistance: Highly resistant to sun exposure after special treatment, maintaining stable performance under long-term UV exposure; exhibits strong resistance to acids, alkalis, salts, and other chemicals, with a service life extending to decades when protected from direct light.
3. Construction Adaptability: Lightweight with flexible width options, enabling convenient transportation and installation. Its mature welding technology allows for reliable seams, making it suitable for complex subgrade conditions and construction in cold regions.
Main Application Areas
1. Environmental Protection Projects: Used as impermeable liners in landfills and wastewater treatment plants to prevent contaminant infiltration into groundwater.
2. Water Conservancy and Municipal Engineering: Applied in tunnel composite linings, dam seepage control, artificial lakes, and channel waterproofing to reduce water loss.
3. Transportation and Agricultural Engineering: Employed in roadbed waterproofing for highways and railways, as well as in fishponds and shrimp farm linings, improving aquaculture efficiency.
