Performance characteristics:

1. Strong anti-seepage performance

High anti-seepage coefficient: Rough surface geomembrane has a very low permeability coefficient, usually much lower than 1.0 × 10-13cm/s, which means it can effectively prevent the infiltration of water molecules and other harmful substances, ensuring the long-term stable operation of engineering facilities.

Widely used: In hydraulic engineering, such as reservoirs, dams, canals, etc., rough surface geomembranes can effectively prevent water infiltration and erosion, improving the safety and stability of the project. Meanwhile, in environmental protection projects such as sewage treatment and landfill sites, it can also play an important role in anti-seepage.

2. Good durability and aging resistance

Anti aging ability: After special treatment, the rough geomembrane has good anti-aging, anti ultraviolet and anti decomposition ability, and can maintain the stability of its physical and chemical properties under various environmental conditions for a long time.

Long service life: Due to its excellent durability and aging resistance, the service life of rough surface geomembranes can reach 50-70 years, providing long-term and reliable anti-seepage guarantee for engineering facilities.

3. Good corrosion resistance

Chemical stability: Rough faced geomembranes have excellent chemical stability and can resist the erosion of various chemical substances, including more than 80 strong acid and alkali chemical media such as acids, alkalis, and salts. This enables it to exhibit excellent anti-seepage effects in corrosive environments such as sewage treatment and chemical reaction tanks.

4. Strong tensile strength

High strength and high elongation: Rough faced geomembranes have high tensile strength and elongation, and can maintain stable performance under large temperature and humidity changes. This characteristic enables it to be used in various complex geological conditions without fracturing or failing due to soil movement or deformation.

5. Rough surface design enhances friction

Increasing friction: The surface of rough geomembrane has rough stone patterns or column point designs, which increase friction with soil or other materials, preventing sliding or leakage. At the same time, it can also increase the area combined with the soil and improve the anti-seepage effect.

6. Convenient construction

Lightweight materials: Rough faced geomembranes are relatively lightweight, making them easy to transport and install, and reducing engineering costs.

There are various connection methods: During the construction process, rough surface geomembranes can be connected by welding or bonding, which is simple and fast to operate.

Landfill: High density polyethylene geomembrane is commonly used as an inner lining for landfills to prevent leachate from contaminating groundwater. Leachate contains substances that are harmful to the environment.

Ponds and lagoons: They are used as linings in decorating ponds, fish ponds, lagoons, and artificial lakes to prevent water leakage to the ground.

Reservoirs and storage tanks: They are also used as linings for reservoirs, storage tanks, and other facilities that store water, other liquids, and even gases.

Canal: High density polyethylene geomembrane is commonly used for lining canals, ditches, or other waterways to prevent soil erosion.

Mining industry: In the mining industry, they are used as linings for tailings ponds and leaching ponds to prevent pollution of the surrounding environment.

Agriculture: In agriculture, they can be used to irrigate ditches, farm ponds, and even to fill manure lagoons.

Construction: It can be used as a moisture-proof layer under concrete slabs or inside basement walls to prevent moisture from entering.

Environmental remediation: They are used in environmental remediation projects to contain pollutants or prevent their spread to neighboring areas.

Oil and gas industry: They can be used for secondary sealing of fuel storage tanks to prevent any potential leakage and pollution of the surrounding environment.

Aquaculture: In aquaculture, high-density polyethylene geomembrane is used in fish and shrimp ponds to maintain water quality and prevent diseases.

The above are just a few examples, and the use of high-density polyethylene geomembrane may vary greatly depending on the specific requirements of the project.

Construction plan specifications:

Do not drag or forcefully pull the geomembrane during transportation to avoid sharp objects from puncturing it.

1. It should extend from the bottom to the high position, without pulling too tightly, leaving a margin of 1.50% for local sinking and stretching. Considering the actual situation of this project, the slope will be laid in a top-down sequence;

2. The longitudinal joints of adjacent frames should not be on the same horizontal line and should be staggered by more than 1m from each other;

3. The longitudinal joint should be at least 1.50m away from the dam foot and bend foot, and should be set on a flat surface;

4. First, the bottom of the slope;

5. When laying the slope, the direction of the film should be basically parallel to the maximum slope line.

Technical indicators of rough HDPE geomembrane 

1、 Physical performance parameters

1. Density and thickness: The density of HDPE rough surface geomembrane is usually greater than 0.94g/cm ³, ensuring its excellent physical properties.
