The polyethylene geomembrane is made of 97.5% polyethylene virgin resin, 2.5% carbonblack, antiaging agent, antioxidant,ultraviolet absorber, stabilizer and other additives,by internationally advanced multiple Layer coextrusion blow molding process or multihead flat extrusion process.
The geomembrane has excellent resistance to chemical acid and alkali, UV resistance, strength,durability and high tear resistance.all products can be produced on ASTM/GRI-GM13 standards.
√ Weldable- can be welded by welding machine.
√ Anti-age- the span life of virgin material is more than 70 years.
√ Anti-UV- can be exposed in the sun.
√ Temperature resistance- still have good performance in temperature range -70°C~150°C.
√ Puncture resistance- no additional protection procedure needed during installation.
√ Corrosion resistance- acid and alkali resistant corrosion.
Our Anti-seepage HDPE film is manufactured via triple co-extrusion technique by the most advanced automatic equipment. All the productions are manufactured according to US GRI standards and ASTM, complete specifications with superior quality. The width can reach 8m. Anti-seepage HDPE geomembrane IS far more cost effective, environmentally safe, excellent durable, chemically resistant, fast deployment and easy transportation than traditional concrete, asphalt and compacted clay.

Applications
1. Strong bearing capacity
There is no loss or mixing between material, so that the carry capacity of the constructure is strengthened.
2. Excellent flexibility
High composite strength, high peel strength and resistance to punch.
3. High waterproof property
It integrate impermeable water and drainage function with isolation and stregthening function at the same time.
4. Stable performance
With the carefully selected material, it's no easy for water seepage and aging.
5.Polyethylene material
Using polyethylene hdpe materials and we select material strictly.
6. Construction Convenience
As it is very light and with good material flexibility, it's convenient to transport and make construction.
7. Good acclimation
it's no easy to degrade and corrode in soil and water with different PH and can be stable for a long time.
Technical Notes
HDPE is a very technical product to work with. It must be installed by certified welding technicians using specialized welding equipment to ensure performance.
Installations are temperature and poor weather sensitive.
40 mil HDPE liner requires extra effort to ensure that the subgrade is in excellent condition. It is suitable as an upgrade from products like the 20 mil RPE for larger installations and is an excellent secondary containment liner on multi-layer systems (for example; subgrade, geotextile layer, 40 mil
HDPE layer, drainage net layer, 60 mil HDPE layer, geotextile layer, fill.)
60 mil HDPE liner is the staple of the industry and is suitable for most applications.
80 mil HDPE liner is a thicker design for more aggressive subgrades.
HDPE Lining materials are a cost effective choice for exposed lining projects because the geomembrane is UV stable and requires no soil cover. This product has been used in landfills, WWT lagoons, animal waste lagoons and mining applications due to its high chemical resistance. HDPE geomembrane can be bonded via a wedge weld or fusion weld to create a strong and seamless system. The range in available thicknesses, from 40 mil to 120 mil, allow the technology to suit many applications.
