What is polyethylene geomembrane?
Polyethylene geomembrane is made of polyehylene resin,it is 100% virgin.The polyethylene geomembrane had different kinds,HDPE geomembrane, LDPE geomembrane, and LLDPE geomembrane,and the popular polyethylene geomembrane are HDPE and lldpe geomembrane.
HDPE geomembrane is made of high-density polyethylene resin, with carbon black material. The lldpe geomembrane is made of the Linear low-density polyethylene resin.
Polyethylene geomembrane features:
- Waterproof, Low Impermeable
- High Mechanical property
- Excellent chemical resistance.
- Good UV resistance.
- Nice Puncture resistance
- Stable low-temperature embrittlement resistance.
- Cost-effective.
- Nontoxic, environment friendly
- Meet or exceed ASTM GRI GM13 and GM17.
The polyethylene geomembrane is waterproof, impermeable, and uv resistant.It is widely used for the aquaculture ponds, water treatment, landfill,mining, root barrier and so on.
- Aquaculture projects: fish ponds, shrimp ponds, industrialized aquaculture ponds.
- Landfill&dump: capping,municipal, industrial, hazardous,sewage treatment plants, power plant pools, solid wastes.
- Agriculture: Seepage control of reservoirs, water reservoirs, irrigation systems,animal waste.
- Oil&gas:drill pad,fresh water pond,pit liner,flow-back water pond,secondary containment,oil containment and storage.
- Water Managenment:water reservoir, laogoon,dam,canal,channels,water treatment.
- Infrastructure:golf-course,coal ash,solar&pumped storage ponds,solar salt.
- Alternative Energy:biogas digester,biogas generating pit,thermal energy storage .
- Mining: heap leaching pads,tailing, evaporation ponds,caps and closures, final disposal reservoir.
Technical Notes
- Polyethylene geomembrane is a very technical product. It must be installed by certified welding technicians using specialized welding machines 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.
- 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.
