What is HDPE Geomembrane?

HDPE Geomembrane, in a word, is High-Density Polyethylene Geomembrane.

HDPE Geomembrane Definition

HDPE Geomembrane is a waterproof barrier material produced from high-density polyethylene resin. (Geomembrane with a density of 0.94g/cm3 or more).

The full name of HDPE Geomembrane is “High-Density Polyethylene Geomembrane”, which has excellent resistance to environmental stress cracking, low-temperature resistance, anti-aging, corrosion resistance, and a large operating temperature range (-60–+60) and long service life (≥50 years) is used in anti-seepage projects such as domestic waste landfills, solid waste landfills, sewage treatment plants, artificial lakes, and tailings treatment.

HDPE Geomembrane Types

HDPE Geomembrane can be divided into hdpe textured geomembrane and hdpe smooth geomembrane according to the appearance surface. hdpe textured geomembrane has an anti-skid function and is more used in projects such as inclined slopes. HDPE Geomembrane can also be divided into 30 mil hdpe liner, 40 mil hdpe liner, 60 mil hdpe liner, 80 mil hdpe liner, and so on according to the thickness. Like the more famous GSE HDPE Geomembrane, Solmax HDPE Geomembrane is also classified in this way.

HDPE Geomembrane Thickness

HDPE geomembrane refers to high-density polyethylene geomembrane, which is a new polymer material, and its thickness generally ranges from 0.2mm to 3.0mm. The most common thickness of HDPE geomembrane is 0.75mm HDPE geomembrane, 1.0mm HDPE geomembrane, 1.5mm HDPE geomembrane, 2.0mm HDPE geomembrane, 2.5mm HDPE geomembrane, 3.0mm HDPE geomembrane.

For example, in the landfill liners project, a 2mm HDPE geomembrane can be selected to ensure that no garbage leakage, sewage leakage, etc. will occur; in a fish pond liner project, a 0.75mm HDPE geomembrane is usually selected to meet the requirements of the fish pond. In the shrimp pond liner project, because the shrimp may have sharp thorns, it is best to choose an HDPE geomembrane with a thickness of 1.0mm or more. If you do not know how to choose the appropriate thickness of HDPE geomembrane liner for different applications, you can contact us and we will provide you with the correct and perfect solution.

HDPE Geomembrane Construction method

Do not drag or pull the geomembrane during transportation to avoid being stabbed by sharp objects.

①. It should extend from the bottom to the high position, do not pull it too, and leave a margin of 1.50% for local sinking and stretching. Taking into account the actual situation of the project, the slope is laid in the order from top to bottom

②. The longitudinal joints of two adjacent sheets should not be on a horizontal line and should be staggered by more than 1m

③. The longitudinal joint should be more than 1.50m away from the dam foot and the bent foot and should be set on the plane

④. Slope first and then the bottom of the field

⑤. When laying the slope, the direction of film expansion should be parallel to the largest slope line

HDPE Geomembrane Climate Requirements

①. The temperature should generally be above 5 degrees Celsius, the geomembrane should be tighter at low temperature, and the geomembrane should be relaxed at high temperature

②. The wind is below level 4

③. When the temperature is too low, the construction should generally not be carried out in strong winds above level 4 and in rainy and snowy weather

④. In windy weather, when the wind affects the construction of the geomembrane, the HDPE Geomembrane to be welded should be pressed with sandbags

HDPE Geomembrane Premium Features

①. Simple construction: as long as the pond is dug and leveled, no concrete cushion is required

②.  Fast construction: there is no solidification period required for structural concrete

③. Resistance to foundation deformation: Because HDPE Geomembrane has a good elongation at break, it can resist foundation settlement or foundation deformation

④. Good effect: This is the biggest feature of HDPE Geomembrane

⑤. Recovery after use: This is the biggest feature of HDPE Geomembrane. After use, as long as it is put away and the pool body is backfilled, it can be restored to its original state

HDPE Geomembrane VS LLDPE Geomembrane

HDPE is high-density polyethylene with excellent chemical resistance, mechanical properties, environmental stress crack resistance, dimensional stability, and heat aging resistance, as well as excellent resistance to ultraviolet radiation and is suitable for open-air environments. LLDPE is linear low-density polyethylene, HDPE geomembrane is harder, LLDPE geomembrane is softer, HDPE geomembrane, LLDPE geomembrane can be used as impermeable geomembrane manufacturing materials.

Polyethylene geomembrane is composed of HDPE (high-density polyethylene) and LLDPE (linear low-density polyethylene) geomembrane. Compared to LDPE, LLDPE is more heat-resistant, stronger, and has better resistance to environmental stress due to the polymerization of ethylene and others such as butane, hexane, and octane.
