Description
Geotextile Description
It can be the filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.

Geotextile Pictures
Features:
1.Engineered to provide high strength and high elongation at break to ensure excellent resistance to damage during construction.
2.Manufactured from high tenacity UV stabilised virgin polypropylene or polyester fibers which have been heavily drawn to ensure excellent long term durability in all soil types.
3.Manufactured using a randomly orientated web to provide completely isotropic properties,ensuring that high strength is not limited to a single direction.
4.Excellent uniformity with high permeability and low pore size for soil filtration.
5.Supplied to a maximum width of 6.5mts,ensuring minimum waste over large construction areas.
6.100% polypropylene or polyester staple fibers ,needle punched and random network formation.
7.UV and rot resistant and biological degradation resistant.
8.Filtration
It can be the filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.
9.Separation
The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different
granule pathway from the groundsill or other buildings.
10.Reinforcement
The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earthbody stability.
11.Protection
It prevents the bank from being washed out, protects the bank and the
bottom, prevents the water and soil from being washed away.
Applications:
While the nonwoven fabric can be used in almost any stabilization,separation or cushioning application,they are most commonly used in areas that also require filatration.The non woven design of the material provides a higher rate of flow through,making it easier for water to pass through the material.
Some commen uses of the material includes the following:
1.Road stabilization applications
2.Roofs
3.Civil applications
4.Railway work
5.Landfill lining
6.Trenches
7.Dams
8.Fitration under rip rap and rocks
9.Environmental applications
