Geosynthetics are the general term for synthetic materials for civil engineering applications. As a kind of civil engineering materials, it is a synthetic polymer (such as plastic, chemical fiber, synthetic rubber, etc.) as raw materials, made of various types of products, placed in the soil, the surface or between the various soil , Play to strengthen or protect the role of soil. "Geosynthetics application of technical specifications" will be divided into geotextile geotextile geotextile, geomembrane, geotextile materials and geotextile composite materials and other types.
Geotechnical special materials include geomembrane bags, geotextiles, geotextile mats, geocells, geotextile bentonite mats, polystyrene foam (EPS) and so on. Geomaterials are made from the above materials, such as composite geomembrane, composite geotextile, composite geotextile, composite waterproofing and drainage materials (drainage, drainage) and so on.
According to the manufacturing method, can be divided into woven geotextile, knitted (mainly warp) geotextile and non-woven geotextile.
Short fiber acupuncture geotextile, short fiber acupuncture geotextile is the use of polyester or polypropylene staple fiber by carding or net needle assassination made of consolidation.
The product has excellent water permeability, filterability, durability, can be widely used in railways, highways, sports museum, dams, hydraulic construction, then hole, coastal beach, reclamation, environmental protection and other projects.
