What is geomembrane

Geomembrane is a kind of waterproof barrier material based on high polymer.

Advantages of geomembrane：

Environmental stress cracking resistance: Can resist cracking caused by environmental stress.

Chemical corrosion resistance: Good resistance to various acids, alkalis, salts and oils (except halogen hydrocarbons)

Wide temperature range: Suitable for engineering applications under a variety of temperature conditions.

Long service life: Long service life in the case of light avoidance

Application field：

Landfill: Used to prevent landfill leachate from contaminating groundwater.

Tailings storage yard: Prevent tailings from leaking and causing environmental pollution.

Channel seepage prevention: Reduce water waste.

Dam seepage prevention: Improve the flood control capacity of the dam.

Subway engineering: Prevent underground water from seeping into subway tunnels

The laying of geomembrane：

Preparation: Before construction, the site needs to be cleaned to ensure that the surface is smooth and free of debris and debris. At the same time, the size of the land should be measured to 

determine the area of the required geomembrane.

Laying film: Unfold the geomembrane and lay it flat on the ground to check whether there is damage or leak. The geomembrane is then firmly fixed to the ground, which can be fixed using 

anchor nails or sandbags.

Trim the edges: After the laying is completed, the edges of the geomembrane need to be trimmed to ensure that the geomembrane is tightly integrated with the ground to prevent penetration.

Fill the soil: Fill the soil inside the geomemofilm, taking care to avoid excessive compaction and maintain the aeration and permeability of the soil.

Anchor edge: After filling the soil, the edge of the geomembrane needs to be anchored again to ensure that the geomembrane is tightly bound to the ground to prevent leakage.

Inspection and maintenance: After the construction is completed, it is necessary to carry out leakage detection to ensure that the geomembrane does not leak. At the same time, it is necessary to check and

 maintain the geomembrane regularly, and repair or replace it in time if it is damaged.

To sum up, geomembrane plays an important role in many fields such as environmental protection and water conservancy engineering because of its excellent impermeability, corrosion resistance and aging resistance.
