Product Description

 

Product Description

High quality composite geomembranes have characteristics that are not present in geomembranes made from general materials, mainly including:
1. The width can reach six meters. Compared with similar products with narrow widths, it reduces joints, lowers engineering costs, shortens construction periods, and also reduces hidden dangers caused by improper joint treatment.
2. Compared with traditional separation of cloth and membrane, the use of composite geotextile membrane improves the effectiveness, saves more engineering time, reduces engineering costs, and has significant comprehensive benefits.
3. Good anti-aging performance. If buried laying is used, the service life will be longer.
4. Water pressure resistance, corrosion resistance, high strength, wear resistance, low temperature resistance, non toxicity, good flat drainage function, and excellent anti-seepage effect.
5. It has unique insulation, moisturizing, anti frost, and anti freezing effects.
In addition, the use of high-quality composite geomembranes is also quite extensive, currently mainly used in some large-scale projects, such as rockfill dams, masonry dams, and compressed concrete dams; Horizontal anti-seepage cover in front of embankment and dam, vertical anti-seepage layer of foundation; Tailings dam, sewage dam body and storage area; Construction cofferdam; Channels and storage tanks (pits, ponds); Waste disposal site; Subway, basement, tunnel, and tunnel anti-seepage lining; Roadbeds for highways, expressways, and railways; Salt prevention and control of roadbed and other foundations; Waterproof layer for expansive soil and collapsible loess, etc.

application

Composite geomembrane, as an important geosynthetic material, plays an important role in multiple fields. The following are the main application areas and functions of composite geomembranes:

Soil anti-seepage: Composite geomembranes, with their excellent anti-seepage performance, are widely used in environmental protection projects such as landfill sites and chemical waste treatment sites to prevent toxic substances from infiltrating groundwater and protect the ecological environment.

Land use: In agriculture, landscaping, and land development projects, composite geomembranes can serve as isolation layers, reduce soil erosion, improve land use efficiency, and promote plant growth.

Hydraulic engineering: Composite geotextile membranes are used for water conservancy facilities such as embankments, reservoirs, and rivers, which can enhance their structural stability, improve flood control capabilities, and have significant effects on preventing floods.

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.
