Products Description
Geotechnical mat is a new type of geosynthetic material made of messy wire melted and laid. It has high pressure resistance, large opening density, and has all-round water collection and horizontal drainage functions.
1、High pressure resistance, high open hole density, with all-round water collection and horizontal drainage function. 2、After the geotextile mat is compounded with non-woven geotextile, it can collect the rainwater penetrating through the soil cover layer or the sewage discharged from the yard itself under the buried closed cover layer, and use its unique drainage function to discharge from the geotextile mat sandwich layer in an orderly manner according to the engineering requirements, without forming silting. Therefore, it can avoid the possible sliding problem due to the water absorption saturation of soil cover layer. 3、Geomat mat can not only drain water, but also discharge the methane gas produced by fermentation in the soil (especially waste waste), which is especially suitable for application in landfill. 4, geotechnical mat and HDPE combined application, at the same time can play a good role in protecting the HDPE membrane from puncture.
