Production & Package
BPM needle-punched non woven geotextile is the most widely used geotextile on civil projects such as road construction,dam and slope protection etc.The main function is filtration, drainage, reinforcement. It has good impermeability and resistance to deformation.
Filtration, drainage, reinforcement
(1) Reinforcement in retaining wall backfill.
(2) Strengthen the weak road and fix the cracks on the road.
(3) Improve the stability of slope and reinforcement soil, avoid water and soil loss and soil frozen injure.
(4) Isolation layer of artificial backfill soil stone with foundation and different tundra.
(5) Filtration layer of drainage pipe or gravel sub-drain.
(6) Vertical or horizontal drainage; Bury in soil to release air pressure.
(7) Reinforce the weak foundation of engineering of road, railway, embankment, airport.

Production: BPM needle-punched non woven geotextile is produced from Polyester or polypropylene fiber by different equipment and technology to get different thickness.Mainly include Fiber mixing,laying and formation,several times laying,needle punched,rolling and package.
Package: Rolling by cardboard core and packed by white woven geotextile with neat state.
