geotextiles

3D drainage network of composite geotextiles refers to a three-dimensional network structure made of polymer synthetic materials, including geotextiles and geonet or geonat, which can form a composite, solid and green protection layer, is light and easy for construction, and has the function of composite protective layer, can withstand the water flow at large flow rate. 3D network with geotextiles has 3-layer special structure, the middle geonet forms the drainage channel and serves as a support to prevent geotextile embedding into the channel, and thus realize the comprehensive property of “filtration-drainage-permeability--protection”.

Geotextile is a new type of building material, and the raw material is polyester synthetic fibers of high molecular weight polymers such as polypropylene. Geotextile has a good adaptability for deformation and the ability of plane drainage, owns soft surface and good friction coefficient, and can increase the adhesion ability of soil particles and other particles, and also prevent the loss of fine particles.

Woven geofabrics is also named as woven geotextiles, generally made of virgin polypropylene particles, and owns good mechanical properties, woven geotextile also owns good vertical and horizontal drainage performance and good elongation properties and high chemical stability, such as anti-deformation, acid and alkali resistance and aging resistance. Moreover, woven geofabrics produced by our company has a wide range of pore sizes, excellent permeability and filtration performance.
