PET Polyester Needle Punched Non Woven Geotextile Fabrics

Non Woven Geotextiles Description
Nonwoven Geotextile Fabric are one of the most popular options for drainage, filtration and stabilization. They are constructed in a felt-like fabric and are very light weight. PET Nonwoven Geotextile Fabric are used to reinforce the construction area and are commonly used around pipes, underneath drains, ditches and any other areas that deal with high levels of runoff drainage from the site.
HUATAO provides a number of different Non woven and woven geotextiles to improve run off around the construction sites.

Non Woven Geotextile Fabric Funtion 

1. Geotextile has good air permeability and water permeability which can pass the water out and intercept the sand running-down
2. Geotextile has high water diversion property, it can form drainage passageway, transpire the surplus liquid and gas
3. High water permeability even under the pressure of soil and waterSpread, transfer or decompose the concentrate stress effectively to avoid the soil be damaged by outside affection
4. To prevent the freestone upper and lower level, soil and concrete mixed
5. Polypropylene fiber or polyester fiber and other chemical fiber as raw material, acid-alkali-proof, corrosion resisting, non warm-eaten,antioxidant Light, convenient to use, easy construction, shorten working-period, increase economic efficiency
6. Make use of geotextile to strengthen the tensile strength and anti-deformation property of soil, increase the stability of building structure, and also improve the soil quality

Nonwoven Geotextile Application

FILTRATION
In earth fillings for road works, coastal and water works (e.g. earth dams), river banks and vertical drainage.

REINFORCEMENT – WATERPROOFING
In earth fillings of dams, stabilisation works, tunnels, membranes, side or vertical drainage e.t.c.. In this case its high porosity facilitates the quick elimination of water.
In stabilisation construction, earth fillings and road surface repairs, it stops or reduces crack propagation.

DRAINAGE
In water reservoirs, dams, tunnels and open earth channels, a non woven geotextile impregnated by resins or tar forms a water proofing medium.
SEPARATION
In earth fillings for road and rail works and port wave breakers. Separates two layers of different particle size and distribution with resultant savings in necessary volume.

PROTECTION – STABILISATION
Protection and stabilisation of soils of low load – carrying capacity, of tunnels, coastal works, membranes e.t.c. In this case local loads are redistributed by the non woven geotextile thus preventing subsidence.
