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.
new composite geomembrane has good flexibility. In addition to the isolation, drainage, reinforcement and protection functions of geotextile, it also has the sealing and anti-seepage functions of geomembrane. It is an ideal anti-seepage material and is widely used in water conservancy and traffic tunnel projects such as channels, tunnels, plain reservoirs, dangerous reservoir anti-seepage reinforcement, and rockfill dam anti-seepage

In the construction of composite geomembrane, sand or clay with smaller material diameter is first selected to level the base surface, and then the geomembrane is laid. The geotextile should not be too tight, and the parts buried in the soil at both ends should be corrugated. Finally, a transition layer of about 10cm should be laid on the geotextile with fine sand or clay, and a 20cm~30cm block stone (or precast concrete block) should be laid as an anti erosion protection layer. During construction, efforts should be made to avoid stones directly hitting the geotextile membrane, and it is best to apply a protective layer while laying the membrane. The connection between composite geomembrane and surrounding structures should be anchored with expansion bolts and steel plate pressure strips. The connection area should be coated with emulsified asphalt (2mm thick) for bonding to prevent leakage.
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.
Precautions during construction:
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.
