First, needle-punched non-woven geotextile, any choice between 100g/m2-1500g/m2, the main raw material is made of polyester staple fiber or polypropylene staple fiber, which is made by needle-punching method. The main purposes are: river, sea and lake The slope protection of the dike, the construction of the land, the docks, the locks of the ship locks, etc. are effective ways to maintain soil and water and prevent flooding through back filtration.

 Second, acupuncture non-woven fabric and PE film composite geotextile, the specification has a cloth one film, two cloth one film, the main raw material is to use polyester short fiber needle-punched non-woven fabric, PE film through composite, the main purpose is to prevent Seepage, suitable for railways, highways, tunnels, subways, airports and other projects.

Third, non-woven and woven composite geotextile, the variety of non-woven and polypropylene filament woven composite, non-woven and plastic woven composite, suitable for basic reinforcement, adjustment of the permeability of the basic engineering facilities. The non-woven geotextile also includes a woven geotextile, which has the characteristics of light weight, high strength, small elongation, good integrity, convenient construction, good reinforcement performance and low price. According to the material, it can be divided into polyester geotextile and polypropylene geotextile; it can also be divided into filament geotextile, short filament (small fiber) geotextile staple fiber geotextile, mainly polyester staple fiber needled geotextile and polypropylene staple fiber needled geotechnical Cloths are all non-woven geotextiles. They are characterized by good flexibility, acid and alkali resistance, corrosion resistance, aging resistance and convenient construction.
