Product Description

 

Product Description

 

Composite geomembrane is an anti-seepage material composed of geotextile and geomembrane. It is mainly used for anti-seepage. Composite geomembrane is divided into two types: thin film, cloth film, and cloth film, with a width of 4-6 meters and a weight of 200-1500 g/m2. Its physical and mechanical properties include high tensile strength, tear resistance, and rupture resistance. Satisfy civil engineering, water conservancy, municipal construction, transportation, subway, tunnel, etc Because of the use of high molecular materials and the production process of anti-aging agent, it can be used in unconventional temperature environment.

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.

Road engineering: In road construction, composite geomembranes can be used to reinforce foundations, improve the stability and bearing capacity of roadbeds, and extend the service life of roads.

Construction engineering: The application of composite geomembranes in the construction field includes waterproof layers, thermal insulation layers, and sound insulation layers, effectively improving the performance and comfort of buildings.

Desertification control and saline alkali land transformation: Composite geomembranes can help fix sand and retain water, improve soil structure, and promote ecological restoration in these environments.

Disaster prevention and control: In disaster prevention and control projects such as flood control and rescue, composite geomembranes can quickly construct temporary or permanent anti-seepage facilities.

When applying composite geomembranes, it is necessary to follow relevant national regulations for construction to ensure that the performance indicators of the materials meet the engineering requirements, and the construction technology should be correct to fully exert its effects. For example, during the laying process, attention should be paid to the treatment of joints to ensure the anti-seepage effect, while also taking into account the special characteristics of the construction environment, such as climate conditions, soil types, etc., to ensure that the composite geotextile can play its role stably in the long term.
 

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.
