Anti-seepage geomembrane

Impervious geomembrane has good tensile strength, high impact strength, impermeability, acid and alkali resistance, heat resistance, weather resistance, wear resistance, etc. Impervious geomembrane has been widely used in the construction industry in coastal areas. It is also widely used in river dams, reservoirs, diversion tunnels, highways, railways, airports, underground and underwater projects. Geomembrane has become an important material for modern national economic construction. The production technology of anti-seepage geomembrane is also introduced.

With the rapid development of economic construction in the coastal areas, real estate development is heating up. Hotels, restaurants, luxury residences, and office buildings are in a row. There are many new apartments and sanatoriums by the sea. However, due to the concave terrain in the coastal areas, groundwater has penetrated upwards. Seriously affect building construction. The anti-seepage geomembrane produced by the calendering biaxial stretching process is used to block groundwater from seeping up due to its good tensile strength, high impact strength, impermeability, acid and alkali resistance, heat resistance, weather resistance, and foot damage resistance. It is used by people in building construction. According to the size of the construction site, the construction unit glues the anti-seepage geomembrane together with high-frequency welding or adhesive tape, and lays it on the rammed foundation. It is covered with sand and soil, and the geomembrane is left on the foundation under. Strictly speaking. The quality of Anti-seepage geomembrane will affect the construction quality of the building.

1. Chemical stability—HDPE impervious membrane has excellent chemical stability and is widely used in sewage treatment, chemical reaction tanks, and landfill sites. Resistance to high and low temperature, resistance to asphalt, oil and tar, acid, alkali, salt, etc.
2. Anti-aging performance-HDPE anti-permeability film has excellent anti-aging, anti-ultraviolet, anti-decomposition ability, can be used barely, and the service life of the material is 50-70 years, which provides a good material guarantee for environmental impermeability.
3. Resistant to plant roots-Impervious geomembrane has excellent puncture resistance and can resist most plant roots
4. High mechanical strength—the impervious geomembrane has good mechanical strength, tensile strength at break of 28MP, and elongation at break of 700%
5. Low cost and high efficiency—Impermeable geotechnical membrane adopts new technology to improve the anti-seepage effect, but the production process is more scientific and fast, so the product cost is lower than traditional waterproof materials. According to actual calculation, the general project of HDPE anti-seepage membrane To save costs by about 50%
6.Fast construction speed-anti-seepage geomembrane has high flexibility, there are many specifications and various laying forms to meet different engineering anti-seepage requirements, using hot-melt welding, high welding strength, convenient construction, fast and healthy
7. Environmental protection and non-toxicity-The materials used in the anti-seepage geomembrane are all non-toxic and environmentally friendly materials. The principle of anti-seepage is ordinary physical change without any harmful substances.
8. Welding effect is good-the anti-seepage geomembrane uses a special welding machine to achieve very good welding results.
High tensile strength and excellent elasticity: HDPE impervious membrane has high tensile strength and mechanical resistance. Its excellent elasticity and strong deformation ability make it very suitable for expanding or contracting the base surface, and it can effectively overcome uneven settlement of the base surface. .
Good impermeability: The Anti-seepage geomembrane is made of high-quality high-density polyethylene primary resin and made by co-extrusion technology. It has high-efficiency molecular density, extremely low liquid permeability, and excellent impermeability.
Simple and convenient construction, light weight, and easy transportation: The Anti-seepage geomembrane is light in weight, and the finished product is rolled, which is convenient for laying on site. It has high flexibility to meet the needs of different construction sites.

Excellent physical and chemical properties: 

HDPE impermeability film is anti-aging, anti-ultraviolet, excellent tear resistance, puncture resistance, low brittleness, small thermal deformation, good chemical stability, high and low temperature resistance, resistance to asphalt, oil and Tar, resistant to acid, alkali, salt and other chemical solutions.

Low cost and high comprehensive benefit: 

HDPE impervious membrane adopts new technology to improve the impervious effect, but the production process is more scientific and fast, so the product cost is lower than the traditional product membrane; the general engineering of HDPE impervious membrane is actually calculated To save costs by 42%.

Health and environmental protection: 

Thematerials used in the Anti-seepage geomembrane are non-toxic and environmentally-friendly materials. The principle of anti-seepage is ordinary physical changes without any harmful substances. It is the best choice for environmental protection and breeding.
