1. Drainage and Filtration of Geosynthetics
Geosynthetic materials, such as non-woven fabrics, can effectively replace traditional gravel filter layers by forming their own drainage channels. These materials collect moisture from the soil and allow it to flow along the surface of the fabric, while simultaneously preventing the loss of fine soil particles and reducing the risk of piping failures. In addition, plastic drainage belts, soft permeable pipes, and filter membranes used in conjunction with plastic blind grooves also contribute to water and soil conservation. These geotechnical materials are widely applied in backwater slope filtration, slope protection, flood control, soft foundation drainage (both vertical and horizontal), waterproofing for underground structures, decompression, seepage control, water-saving irrigation systems, and in parks, playgrounds, landfills, dredged areas, and embankments.
2. Anti-Seepage Function of Geosynthetic Materials
Geosynthetic materials like geomembranes, rubber-coated or resin-coated fabrics—whether woven or non-woven—are increasingly used as alternatives to traditional anti-seepage materials such as clay or asphalt. They provide an effective barrier against water infiltration in various engineering projects. These materials are commonly used in earth dams, reservoirs, landfill linings, and building moisture protection. Their durability, flexibility, and ease of installation make them a preferred choice for long-term seepage prevention and structural stability in civil and environmental engineering applications.
