How to Choose Geomembrane

Observation appearance:

 The appearance of high-quality geomembrane should be black and smooth, and there are no obvious impurity points, The appearance of low-quality geomembrane is the color of hair, rough, and there are obvious impurity points.

Check the feel: 

The high-quality geomembrane feels firm and elastic, and there is no obvious crease after multiple bending. The poor quality geomembrane bending elasticity is poor, there are white creases, multiple bending is easy to break.

Check the test report:

High-quality geomembrane manufacturers will issue a test report and certificate, which is an important scientific basis for quality, and substandard geomembrane manufacturers can not take out the test report and certificate.

Understand the material:

 Geomemofilm mainly has HDPE, LDPE, LLDPE, PVC and other materials, the selection should be determined according to the requirements of the material.

Consider the thickness: 

The thickness of the geomembrane affects its waterproof, durability, damage resistance and other characteristics, the greater the thickness, the better the performance, but the cost will also increase.

Considering the anti-aging ability:

 Considering that the geomembrane is exposed to the natural environment for a long time, it is necessary to choose a geomembrane with good durability and strong anti-aging ability.

Consider environmental protection:

 Choose brands that meet national environmental protection requirements.

Consider the degree of construction difficulty:

 Different materials, thickness, width of geomembrane in the degree of construction difficulty is also different, according to the specific construction conditions.

The specifications of geomembrane in different applications ‌ mainly include parameters such as thickness and gram weight, as follows:

‌ Aquaculture ‌ : 

The general use of 0.5mm~0.8mm thickness of geomembrane, this thickness is enough to meet the anti-seepage needs of aquaculture ‌.

‌ Landfill ‌ :

Usually need 1.5mm~2mm thickness of geomembrane to reduce the risk of leakage ‌.

‌ Small reservoirs and ponds ‌ : 

1mm thick geomembrane is suitable for these small projects because it is easy to transport and store, and the joint treatment is relatively simple ‌.

‌ Large landfill sites and industrial wastewater treatment ponds ‌ :

2mm thickness of geomembrane is more suitable, can cover a larger area, reduce the number of joints, reduce the risk of leakage ‌.

Large water conservancy projects and expressway construction ‌ :

3mm thick geomembrane is suitable for these large-scale projects, with greater coverage area and higher anti-seepage effect ‌.

In addition, the specifications of geomembrane also include width and roll length.     The usual specification is 6 meters wide and 50 meters long ‌.
