ECB Geomembrane - Soft, Flexible Structure for Easy Bending


Two pieces of ECB geomembrane samples in two different colors are lying on the blue background.
ECBG-1: ECB geomembrane can be in different colors.

ECB geomembrane is ethylene vinyl acetate copolymer, through two stages extrusion, three rollers calendering that produce sheet material. It is very similar to EVA geomembrane. The material is translucent body, and it features excellent weather resistance, low temperature resistance, extension rate, impervious, no migration, etc. What's more, it belongs to environmental friendly material. Generally speaking, ECB geomembrane is a compound type product. That is adopt ECB geomembrane sheet and geotechnical cloth to processed into composited geomembrane.

ECB geomembrane is the first choice for the tunnel and dam waterproof projects at home and abroad. Its molecular weight up to 250 thousands. Its good flexibility can meet the requirements of a variety of applications. At the same time, with the advantages of cold resistance, lightweight, elastic, environmental stress cracking properties, it is especially suitable for arch top inner surface waterproof and leakage proof.

ECB geomembrane is widely used in tunnel and dam waterproof engineering, especially applicable for arch top inner surface waterproof and leakage proof. Like the following places:

  • New railway, highway, municipal road, light rail transit construction (including bridges and tunnels).
  • Roofing, underground engineering waterproof, water conservancy construction.
  • Sewage treatment anti-seepage engineering, landfill field engineering, chemical alkali treatment pool.
Some workers are working together to lay the black ECB geomembrane on the small slope.
ECBG-4: ECB geomembrane can be used for highway.
Black ECB geomembrane is laid around the artificial lake, and there is a wire mesh fence to protect the lake.
ECBG-5: ECB geomembrane is suitable for artificial lake.
There is a person operating a small hot welding machine to stick the edges between two black ECB geomembranes.
ECBG-6: ECB geomembrane edge hot welding machine.
White ECB geomembrane is laid on a large area, and there are three people, two cars beside it.
ECBG-7: ECB geomembrane can be used for landfill.
White ECB geomembrane wraps the whole arch of the tunnel, and there are some workers working.
ECBG-8: ECB geomembrane is applicable for tunnels.

The package of ECB geomembrane can be woven bags, and then on pallets, wooden cases or at your requests.

Many rolls of black ECB geomembrane are lying on the ground orderly, and their two sides are tied up by white ropes.
ECBG-9: ECB geomembrane rolls are waiting for packaging.
Numbers of ECB geomembrane are packed with black woven bags, and piled up together orderly in the factory.
ECBG-10: The package of ECB geomembrane is woven bags.
