HDPE Composite Geomembrane for Aquaculture Anti-Seepage Membrane Landfill Flood Prevention Construction HDPE Geomembrane for Heap Invasion Pond Tailings Pond

Product Description

 

Product Description

Composite geomembrane is an impermeable material composed of geotextiles and geomembranes. It is mainly used for anti-seepage. Composite geomembranes are divided into one fabric one membrane and two fabrics one membrane, with a width of 4-6 meters and a weight of 200-1500g/m2. They have high physical and mechanical performance indicators such as tensile strength, tear resistance, and top breaking, and can meet the needs of civil engineering such as water conservancy, municipal engineering, construction, transportation, subway, and tunnel. Due to the use of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments.
 

The product has the characteristics of high strength, good elongation performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, and crack prevention reinforcement in water conservancy, municipal engineering, construction, transportation, subway, tunnel, and engineering construction. Due to the use of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments. Commonly used for anti-seepage treatment of embankments, drainage ditches, and waste disposal sites.

Advantage
1: Excellent flexibility, in addition to the functions of geotextile isolation, drainage, reinforcement protection, etc., it also has a sealing (anti-seepage) function.
2. Good stretchability, with excellent tensile strength, suitable for use in various industries.
3. Strong crack resistance with excellent resistance to environmental stress cracking.
4. Easy to construct with good dimensional stability, good adhesion, and easy construction.
5. Anti seepage This product is used as a waterproof material with high anti-seepage coefficient, strong UV resistance and anti-aging performance.

1. Used for environmental protection and sanitation: such as landfill sites, sewage treatment plants, power plant regulating tanks, industrial and hospital solid waste, etc. 2. It is used for water conservancy projects, such as seepage prevention, leak stoppage, reinforcement of Rivers and Lakes, reservoirs, dams, seepage prevention of canals, vertical core walls, slope protection, etc; 3. Used for municipal engineering: subway, underground engineering of buildings, planting roofs, rooftop gardens, sewage pipe anti-seepage; 4. Used for aquaculture: lining of intensive and factory aquaculture ponds, fish ponds and shrimp ponds, and protecting slopes with sea cucumber pens; 5. Used for transportation facilities: foundation reinforcement of highways, anti-seepage of culverts; 6. Used for landscaping: artificial lakes, waterways, reservoirs, bottom of golf courses, slope protection, waterproof and moisture-proof green lawns, etc; 7. Used in petrochemical industry: lining and secondary lining for chemical plants, refineries, oil storage tanks, chemical reaction tanks, sedimentation tanks, etc. 8. Used in mining industry: bottom lining for anti-seepage of washing tanks, heap leaching tanks, ash yards, dissolution tanks, sedimentation tanks, storage yards, tailings, etc; 9. Used in the salt industry: salt crystallization tank, brine tank bitter cover, salt film, salt tank plastic bitter film; Used for agriculture: anti-seepage of reservoirs, drinking water tanks, storage ponds, and irrigation systems;

Application field of composite geomembrane

Construction precautions
 

The use requires landfill type, and the coverage thickness should not be less than 30 cm.
The entire anti-seepage system consists of a cushion layer, anti-seepage layer, transition layer, and protective layer.
The soil should be solid to avoid uneven settlement and cracks. Grass and tree roots within the anti-seepage range should be removed, and small particle sized sand or clay should be laid as a protective layer on the contact surface with the membrane.
When laying, the geotextile should not be pulled too tightly. It is better for the parts buried in the soil at both ends to form a ripple shape, especially when anchoring with rigid materials, a certain amount of expansion and contraction should be left.
During construction, it is advisable to avoid stones and heavy objects directly hitting the geotextile membrane. It is best to lay the membrane and cover the protective layer while constructing.
 

The joint treatment of rainproof composite geomembrane is a key process that directly affects the anti-seepage effect. The general joint methods include:
Overlap. The overlap width should not be less than 15cm;
Hot welding. It is advisable to use slightly thicker geotextile membrane substrate, with a weld seam overlap width of no less than 5 cm (adhesive bonding is not recommended, as prolonged water immersion can easily open the adhesive and have poor anti-seepage effect). Based on years of practice, it has been proven that the thickness of the geomembrane is not less than 0.25 mm. If it is too thin, it may produce pores and is prone to damage during construction, reducing the anti-seepage effect.
During the construction of geotextile membranes, special attention should be paid to ensuring that the laying is not too tight, wrinkling is not allowed, and the splicing is firm. We must strictly follow the technical specifications for construction, and ensure the quality of preparation, laying, splicing, inspection, and backfilling. For the laid geomembrane, the edge joints must be free of dirt, moisture, dust, etc.
