When overlapping adjacent composite geomembranes, first expose the geotextile at the joints, sew adjacent geotextiles to the bottom layer, and then fit the welding edges of the two membrane layers together. The width of the flap is 150mm.

Repairs should be postponed to areas at least 30 cm outside the size of the damaged composite geomembrane.

In many reservoirs, composite geomembrane uses plastic (thermoplastic polymer), rubber (thermosetting polymer) and composite geotechnical mechanics, but currently my country still widely uses geotechnical mechanics and composite geotechnical mechanics.

Product quality inspection of composite geomembrane materials.

Composite geomembrane is a composite impermeable material, woven or non-woven fabric is used as reinforcement material, and polyethylene is used as impermeable material. Most of the materials are one cloth and one film, and two cloth and one film. Laying impermeable membrane procedure: When laying the impermeable membrane, please make sure that there is no gap in the corner. If there are gaps, they should be filled in time during construction, and the laying order should be determined according to the specific conditions of the moisture content of the laying site. If there are pores, the air should be vented at the air bubble, and the anti-permeable membrane at the vent should be cleaned for subsidies.

The geomembrane is damaged during transportation and on-site construction, which changes the destruction mechanism of the geomembrane and affects its anti-permeability and stress performance. The composite geomembrane uses hot melt technology to bond the membrane to the cloth. The bilateral geotextile can effectively protect the geomembrane from damage. However, in the process of manufacturing and building connection, hot melt technology will inevitably cause thermal burns and defects of the soil membrane, which has the hidden danger of preventing penetration.
