Short fiber PP nonwoven geotextile
Method of Construction
(1) artificial filling foundation movement of ground water.
(2) gravel filter layer surrounding the periphery of the drain pipe drain.
(3) in water conservancy projects wells, relief wells or inclined pipe filter.
(4) for retaining wall backfill reinforcement, or for anchored retaining wall panel.
(5) reinforced flexible pavements, crack repair roads, prevent the reflection cracks of pavement.
(6) in ternal vertical or horizontal drainage, dissipation of pore water pressure in soil.
(7) water impermeable geomembrane dam or embankment in the lower part of the back or the concrete.
(8) the isolation layer between the road ballast and subgrade, isolation layer or between the embankment and soft foundation.
(9) the isolation layer soil between highway, airport, railway ballast and artificial rockfill and soil fabric
