Applications

(1) Filter layer around drainage pipes or gravel drainage ditches.
(2) The filter layer of water wells, pressure relief wells, or inclined pipes in hydraulic engineering.
(3) The isolation layer of geotextiles between highways, airports, railway tracks, and artificial stone piles and the foundation. Non woven geotextile (5 sheets)
(4) Vertical or horizontal drainage inside the earth dam, buried in the soil to dissipate pore water pressure.
(5) Drainage behind the anti-seepage geotextile membrane or below the concrete cover in earth dams or embankments.
(6) Eliminate water seepage around the tunnel, reduce the external water pressure borne by the lining, and alleviate water seepage around various buildings.
(7) Drainage of artificial fill foundation for sports field foundation.
