In April 2022year, our company received an inquiry about HDPE geomembrane liners, the HDPE geomembrane liners are used for landfill projects, and the property should meet the ASTM GM13 standard.
The landfill project is a government project, which is a sanitary landfill, to replace the dumps before. The dump only can collect the waste, but the leachate pollutes the soil and water nearby, very bad for people’s life. So the government hopes to build more and more sanitary landfills to replace the dump ponds and control the water quality and air quality.
After checking the technical data sheet, our engineers talked with the customer procurement department, and ask about their construction experience. The customer doesn’t have any experience with construction and hopes our engineers to the project site. Considering the virus situation, the engineers cannot go immediately and talk about the solution.
Our company HDPE Geomembrane liners are made of 100% virgin polyethylene raw materials, and the main composition is 97.5% high-density polyethylene resin and 2.5% carbon black Masterbatch. The production use blowing film or calendaring process which can make different specifications for customers.
Our HDPE Geomembrane liners features are as follows:
1. High anti-seepage property
2. Chemical resistance
3. Age resistance
4. High mechanical property
5. High economic efficiency
6. Fast installation
HDPE geomembrane liners are also known as HDPE geomembrane liners or dam liners. Our normal HDPE geomembrane liners specifications are as follows:
1. HDPE geomembrane liners Thickness: the range is 0.3-3mm.
Popular thickness are 0.5mm,0.75mm,1mm,1.5mm,2mm
2. HDPE geomembrane liners Color: black color is a popular color, it is UV resistant and exposed to the sunshine.
Other colors are workable, red, blue, and green colors can be customized.
3. HDPE geomembrane liners Surface: smooth surface and textured surface.
Double sides smooth surface is a popular kind, and we can produce one side smooth side textured surface geomembrane liners. The double sides textured geomembrane liners are also no problem.
4. HDPE geomembrane liners width: range 1-8m. The popular width is 5.8m,7m, and 8m.
The roll width can be customized.
5. HDPE geomembrane liners length:1-500m.The popular length is 50m 100m 140m 200m etc.
The length can be customized.
When we talked with the customer about the landfill project, the ASTM GM13 1.5mm thickness HDPE geomembrane liners, the HDPE geomembrane liners technical datasheet is as follows, and the roll size is 8*140m.

During the communication process, a customer asked a question that there is a much lower price, why your price is higher?
This is our answer for reference. PE geomembrane liners need to be produced with 100% virgin resin; yet, In the market, there are a large number of PE geomembrane liners are produced with recycled/used materials to save the production cost. The sources of recycled materials are ambiguous, such as waste machine oil drums, waste mineral water bottles, and waste greenhouse films; also, the quality is unstable, if it is used for a period of time or in a harsh environment, the HDPE geomembrane liners will be damaged and its anti-seepage function will be lost. What’s more, the recycled/used material itself contains a variety of harmful substances, which will cause unpredictable damage to the environment and the human body.
Our company’s commitment to our customers is never to use even one grain of recycled materials! The raw materials used by our company are all qualified materials, especially for HDPE geomembrane liners from world-famous brands. The geomembrane produced by our company has excellent tensile yield strength and resistance to environmental stress cracking. Our suppliers include Singapore Phillips, Nordic Chemical, Dow, Total, Qatar Philips, Korea Oil Chemical, etc.
To help customers understand the difference between virgin material HDPE geomembrane liners and recycled material geomembrane, we show customers some simple methods to confirm.
The surface of 100% Virgin Material Geomembranes is smooth and flat, but, there are bump dots on the surface of the Recycled Material geomembrane The poorer the quality of recycled materials, the more bump geomembrane has on its surface. This is the easiest and fastest method to know the quality, by your eyes and hands.
The HDPE geomembrane liners with 100% virgin raw material don’t have any smell. The geomembrane with recycled material will smell pungent if you smell it. The worse quality of the recycled material, the more pungent the smell. If it is impossible to judge that the geomembrane, can be workable to ignite with fire, the recycled geomembrane will emit a strong peculiar smell.
Another method is to fold the geomembrane sheet. If you fold the geomembrane sheet corner, the recycled geomembrane folded area becomes white, but the virgin geomembrane folded area is still black color.
The virgin material geomembrane is not easy to break and tear, but the recycled material geomembrane can be broken by man’s hands.
Customers are very satisfied with our support and knowledge about the difference between virgin material geomembrane and recycled material geomembrane. And considering the landfill construction, choose our ASTM GM3 HDPE geomembrane liners finally.
