1.raw material: polypropylene 2.weight:100-800g/m2 3.technics:needle-punched 4.Good resistance to corrosion, acids, alkalis

Application:

 It can strengthen in geotechnical engineering , such as, riverbank, dam, highroad, railway, roadbed of airport , etc.

Features:

1.Filtrate: It can permit the air and water passing freely but prevent the gravel passing.

2.Isolation:Separate different quality materials from each other.

3.Reinforcement: it is widely used in airport,retaining wall and slope projects,effectively distributes the bearing capacity and prevent the earth move,and improve the earthwork stability.

4.Protection: avoid soil and water loss
