Anti-Seepage Geotextile

Anti-seepage geotextile LW-001 uses plastic film as the anti-seepage base material and is a geotextile anti-seepage material compounded with Non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. At present, the plastic films used for anti-seepage at home and abroad mainly include () and polyethylene (PE). The anti-seepage geotextile is a polymer chemical flexible material with a small specific gravity, strong extensibility, high deformation adaptability, and durability. 

Corrosion-resistant, low-temperature resistant, and frost-resistant. Its main mechanism is to use the impermeability of the plastic film to block the leakage channel of the earth dam, and its greater tensile strength and elongation to withstand water pressure and adapt to the deformation of the dam body; and non-woven fabric is also a kind of polymer short fiber chemical The material, formed by needle punching or hot bonding, has high tensile strength and extensibility. After it is combined with the plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also due to the rough surface of the non-woven fabric , increasing the friction coefficient of the contact surface, which is beneficial to the stability of the composite geomembrane and protective layer. At the same time, they have good corrosion resistance to bacteria and chemicals, and are not afraid of acid, alkali, and salt corrosion.

Performance characteristics of anti-seepage geomembrane:

1. Chemical stability—HDPE anti-seepage membrane has excellent chemical stability and is widely used in sewage treatment, chemical reaction tanks, and landfills. Resistant to high and low temperatures, asphalt, oil and tar, and resistant to corrosion by more than 80 strong acid and alkali chemical media such as acids, alkalis, and salts.

2. Aging resistance - HDPE anti-seepage membrane has excellent anti-aging, anti-ultraviolet and anti-decomposition capabilities. It can be used naked and has a service life of 50-70 years, providing a good material guarantee for environmental anti-seepage.

3. Resistant to plant roots—HDPE anti-seepage membrane has excellent puncture resistance and can resist most plant roots.

4. High mechanical strength—HDPE anti-seepage membrane has good mechanical strength, with a tensile strength at break of 28MP and an elongation at break of 700%.

5. Low cost and high efficiency - HDPE anti-seepage membrane uses new technology to improve the anti-seepage effect, but the production process is more scientific and faster, so the product cost is lower than traditional waterproof materials. According to actual calculations, general projects using HDPE anti-seepage membrane To save costs by about 50%

6. Fast construction speed - HDPE anti-seepage membrane has high flexibility. It has a variety of specifications and laying forms to meet the anti-seepage requirements of different projects. It adopts hot-melt welding, high weld strength, convenient, fast and healthy construction.

7. Environmental protection - the materials used in HDPE anti-seepage membrane are all environmentally friendly materials. The principle of anti-seepage is ordinary physical changes and does not produce any harmful substances. It is the best choice for environmental protection, breeding and drinking water pools.

8. Good welding effect—HDPE anti-seepage membrane uses a special welding machine to have very good welding effect. The strength of the weld is greater than the strength of the base material, and it is easy to construct.
