Product Details

Drainage sheet material is a new type of geosynthetic material made by fusing random threads with auxiliary mesh. It has high pressure resistance, high pore density, and comprehensive water and horizontal drainage functions. After composite with non-woven geotextile, the permeable sheet material can collect rainwater that has infiltrated the soil cover layer or sewage discharged from the yard itself under the buried closed cover layer. By utilizing its unique drainage function, it can be discharged in an orderly manner from the interlayer of the permeable sheet material according to engineering requirements without forming siltation. Therefore, it can avoid possible sliding problems caused by soil cover saturation due to water absorption. Permeable sheet materials can not only drain water, but also discharge biogas generated by fermentation in soil (especially garbage waste), making them particularly suitable for use in landfill sites. When combined with HDPE, the permeable film can also effectively protect the HDPE film from puncture.

Application:
The scope of use of plastic permeable sheets: 1) reinforcement and drainage of road and railway subgrade shoulders; 2) Drainage of tunnels, subway underground passages, and underground freight yards;
3) Soil and water conservation for hillside and slope development; 4) Vertical and horizontal drainage along various retaining walls; 5) Drainage on slippery surfaces; 6) Drainage of ash piles in thermal power plants. Drainage of landfill engineering; 7) Drainage of rest green spaces such as sports fields, golf courses, baseball fields, football fields, parks, etc; 8) Drainage of rooftop gardens and flower beds; 9) Construction drainage of building foundation engineering; 10) Underground irrigation and drainage systems for agriculture and horticulture; 11) The drainage system of low-lying tidal wetlands. Drainage of land preparation projects.
