Waterproof nonwoven geotextile is a geomembrane material composed of plastic film as impervious material and non-woven fabric. It can effectively intercept the loss of sand, remove the excess liquid and gas in the soil structure, and enhance the stability of the building structure, so as to improve the quality of the soil.
At present, Waterproof nonwoven geotextile for anti-seepage application at home and abroad are mainly polyvinyl chloride (PVC) and polyethylene (PE). They are a kind of polymer chemical flexible materials with small specific gravity, strong extensibility, high ability to adapt to deformability, corrosion resistance, low temperature resistance and good frost resistance. Its main mechanism is to isolate the water leakage channel of the earth dam with the non permeable property of plastic film, bear the water pressure and adapt to the deformation of the dam with its larger tensile strength and elongation, and it is also a kind of polymer short fiber chemical material. It has high tensile strength and extensibility by needle or hot sticky forming, and it is with plastic film. It not only increases the tensile strength and anti puncture ability of the plastic film, but also increases the friction coefficient of the contact surface because of the roughness of the non-woven fabric, which is beneficial to the stability of the composite geomembrane and the protective layer. At the same time, Waterproof nonwoven geotextile have good erosion resistance to bacteria and chemical action, and are not afraid of acids, alkalis and salts.
Dageng brand Waterproof nonwoven geotextile is usually made of PE membrane and PET non-woven geotextile. The structure is of one film one geotextile, one film two geotextile and etc. The roll wide can be from 1m to 6m, or as per request.
