Flexible geomembranes are a member of the geosynthetic family and are widely used in highways, railways, water conservancy projects, large-scale construction, ash‑dam construction at power plants, non‑ferrous metal tailings management, environmental protection engineering, and soil and water conservation. Flexible geomembranes are available in single‑fabric–single‑membrane and double‑fabric–single‑membrane configurations, with widths ranging from 4 to 6 meters and basis weights between 200 and 1,500 g/m². They exhibit excellent physical and mechanical properties, including high tensile strength, tear resistance, and burst resistance. The products feature high strength, good elongation, a high modulus of deformation, resistance to acids and alkalis, corrosion resistance, aging resistance, and superior impermeability. They can meet the seepage‑control requirements of civil engineering applications such as water conservancy, municipal works, building construction, transportation infrastructure, subways, tunnels, and other engineering projects.

Flexible geotextile mats are a member of the broader family of geosynthetic materials and are widely used in highway and railway construction, water conservancy projects, large-scale building works, ash‑dam construction at power plants, non‑ferrous metal tailings management, environmental protection engineering, and soil and water conservation. Flexible geotextile mats are available in single‑fabric–single‑membrane and double‑fabric–single‑membrane configurations. Width 4–6 m, with a basis weight of 200–1500 g/m². It exhibits excellent physical and mechanical properties, including high tensile strength, tear resistance, and burst resistance. The product is characterized by high strength, superior elongation, a high modulus of deformation, and outstanding resistance to acids, alkalis, corrosion, and aging, as well as excellent impermeability. It can meet the requirements of civil engineering applications—such as water conservancy, municipal works, construction, transportation, subway systems, tunnels, and other infrastructure projects—for seepage control, isolation, reinforcement, crack prevention, and structural strengthening.

Because flexible geomembranes are made from polymeric materials and incorporate anti‑aging additives during manufacturing, they can be used in a wide range of temperature conditions. They are commonly employed for seepage control in dams and drainage channels, as well as for pollution prevention at waste disposal sites. Their functions include seepage control and isolation. Applications of flexible geomembranes encompass earth‑rockfill dams, rockfill dams, masonry dams, and concrete‑paved dams; horizontal seepage‑control liners in front of embankments and vertical seepage‑control layers beneath foundations; tailings dams, wastewater‑storage‑dam structures and reservoir areas; the construction of cofferdams; and their extensive use in river channels and reservoirs, thereby helping to protect the ecological environment.

Soft drainage is primarily used in five areas:

1. Environmental protection and hygiene: Flexible liners effectively address the issue of urban solid waste pollution, helping to prevent ongoing environmental contamination.

2. In hydraulic engineering, it is used for dam foundation reinforcement, drainage‑board dewatering, and diversion‑and‑pressure‑reduction applications, among others.

3. Various seepage-control projects, including soft-soil foundation reinforcement and drainage, in municipal construction projects.

4. Flexible liners can be used for seepage control in petrochemical systems, chemical wastewater ponds, refinery wastewater ponds, electroplating and acid‑pickling tanks (providing both seepage prevention and corrosion resistance), as well as for pipeline lining, among other applications.

5. Seepage control and drainage reinforcement beneath road traffic facilities and ballast; seepage control and drainage reinforcement for culverts and tunnels; groundwater diversion and moisture‑proofing along the railway line.

In addition, during construction, the thickness of the flexible mattress shall not be less than 0.25 mm. If the material is too thin, it may develop pinholes and become easily damaged during installation, thereby compromising its impermeability. During the construction of flexible geomembranes, special attention must be paid to ensure that the membrane is not laid too tightly, does not wrinkle, and that all joints are securely bonded. Construction must strictly adhere to technical specifications, with rigorous quality control at each of the five critical stages: preparation, installation, jointing, inspection, and backfilling.
