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. These mats are available in single‑fabric/single‑membrane and double‑fabric/single‑membrane configurations, with widths ranging from 4 to 6 meters and basis weights from 200 to 1,500 g/m². They exhibit excellent physical and mechanical properties, including high tensile strength, tear resistance, and burst resistance. The product also features high strength, good elongation, a high modulus of deformation, resistance to acids and alkalis, corrosion resistance, aging resistance, and superior impermeability. It can meet the demanding requirements of civil engineering applications in water conservancy, construction, transportation, subway systems, tunnels, and other infrastructure 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 two configurations: one‑fabric‑one‑membrane and two‑fabric‑one‑membrane. 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. This product is characterized by high strength, good elongation, a high modulus of deformation, resistance to acids and alkalis, corrosion resistance, aging resistance, and superior impermeability. It can meet the requirements for seepage control, isolation, reinforcement, crack prevention, and structural strengthening in civil engineering applications such as water conservancy, construction, transportation, subway systems, tunnels, and various infrastructure projects.

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 barriers upstream of the dam and vertical seepage barriers in the foundation; tailings dams, wastewater‑storage‑facility impoundments and their reservoir areas; cofferdam construction; and, through composite flexible geomembranes, extensive use in rivers and reservoirs, thereby helping to protect the ecological environment.

Soft volleyball

Soft drainage is primarily used in five areas:

1. Environmental protection and sanitation: 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‑based pressure relief, among other applications.

3. Various seepage-control projects, including soft‑mat reinforcement and drainage in municipal construction works.

4. Flexible drainage pipes can be used in petrochemical systems, for seepage control in chemical wastewater ponds, for seepage prevention in refinery wastewater ponds, for corrosion‑resistant lining of electroplating and acid‑pickling tanks, and as pipe linings, 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, porosity may occur, it can be easily damaged during installation, and its impermeability will be compromised. 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 quality control at five key stages: preparation, installation, jointing, inspection, and backfilling.
