Information

We are professional Nonwoven Geotextile producer, specialized in geotextile, geogrid and other products associated. We have been exclusive geotextile supplier to Australian distributors for more than 6 years, as well as to distributors from other countries, like Russia and Bengal. Base on your needs, we could provide customized geotextiles from US standard (for industrial projects) to economic qualities (for personal use, gardening & swimming pools).

 

Engineering grade nonwoven geotextiles

Profile

Non-woven Geotextiles are made from 100% staple polyester and polypropylene needle-punched filter fabric. They have excellent waterflow rates and drainage for the filtration of soil fines. Non-woven Geotextiles have a variety of uses, some of which include trench drains and wrapping perforated pipe to protect against erosion and being combined with geomembranes to provide protective cushioning. Other uses include tensile reinforcement, filtration, and separation for roads, roofs, railroads, ponds, dams, trenches, landfills, protection for shoreline and membrane liners, sub-grade stabilization, erosion control, and many other civil engineering and construction uses. This product is resistant to tears and punctures, soil chemicals, UV rays, mildew, and freeze thaw.

 

 

Applications

It is sometimes hard to define the functions of the geotextiles, because their functions are almost exploited together: the porous and tough fabrics keep the strength of the soil and aggregates while let water (in most cases rainwater) penetrate therethrough. Such functions (officially defined as separation, filtration, stabilization, erosion control, etc., which can find the specific applications as follows (never exclusive to the mentioned below):

Paved and unpaved roads, railway, airport field, landfill, embankments, retaining walls, slopes, soft foundations, tunnels, landscaping and building structures, etc.

Knitted Geogrid

Warp Knitted geogrid is made from high-strength fibers( polyester fiber or glass fiber), can also call high-strength fibers geogrid. This kind of use strength polymer or glass fiber as material, which woven by weaving machine to be with foursquare holes called warp knitted geogrid which arranged in parallel of latitude and longitude. According to customer demand, could composite geotextile or other kind of material.

 

 

Glass Fiber Geogrid

The glass fiber geogrid is an excellent composite material used for road reinforcement and soft soil foundation improvement.It has become an indispensable material in treatment of reflection crack on asphalt road surface.the product is a semi-rigid mesh base made from high-strength alkaline-free glass fibre through international advanced process and subjected to surface coating.It has a high tensile strength and a lower elongation both vertically and horizontally.Moreover,it has good resistance to high and low temperature,aging and corrosion.It is widely used in asphalt wall,railway foundation,dike slope,runway and sand harnessing.
