Geotechnical mat
Geotextile mat is a new type of geosynthetics made of disorderly wire melting and laying net. It has high pressure resistance, large opening density, and has all-round water collection and horizontal drainage functions. The composition of the structure is a three-dimensional geotextile core, both sides are equipped with needle punched non-woven geotextile. The three-dimensional geotextile core can quickly discharge groundwater, and it also has a pore maintenance system, which can block capillary water under high load. At the same time, it can also play a role in isolation and reinforcement.

Product Introduction
Geotextile mat is a new type of geosynthetics made of disorderly wire melting and laying net. It has high pressure resistance, large opening density, and has all-round water collection and horizontal drainage functions. The composition of the structure is a three-dimensional geotextile core, both sides are equipped with needle punched non-woven geotextile. The three-dimensional geotextile core can quickly discharge groundwater, and it also has a pore maintenance system, which can block capillary water under high load. At the same time, it can also play a role in isolation and reinforcement.
Overview of geotechnical mat
◎ Geotextile mat is a new type of geosynthetic material made of disorderly silk melting net. It has high pressure resistance, large opening density, and has all-round water collection and horizontal drainage functions.
◎ After the geotextile mat and non-woven geotextile are combined, the rainwater that has penetrated through the soil covering layer or the sewage discharged from the yard itself can be collected under the buried closed covering layer, and its unique drainage function can be used to discharge orderly from the geotextile mat interlayer according to the engineering requirements without forming silt blockage. Possible sliding problems due to saturation of the soil cover with water absorption can thus be avoided.
◎ Geotextile mat can not only drain water, but also discharge biogas generated by fermentation in soil (especially garbage waste), which is especially suitable for application in landfills.
◎ When the geotextile mat is combined with HDPE, it can also protect the HDPE film from being punctured.

Effect of geotechnical mat
After the geotextile mat is compounded with the non-woven geotextile, it can collect the rainwater penetrating the soil covering layer or the sewage discharged from the yard itself under the buried closed covering layer, and use its unique drainage function to discharge orderly from the geotextile mat interlayer according to the engineering requirements without forming silt blockage. Possible sliding problems due to saturation of the soil cover with water absorption can thus be avoided. Geotextile mats can not only drain water, but also discharge biogas produced by fermentation in soil (especially garbage waste), which is especially suitable for landfills. When the geotextile mat is applied in combination with HDPE geomembrane, it can also protect the HDPE membrane from being punctured.
Application of geotechnical mat
◎ After the geotextile mat and non-woven geotextile are combined, the rainwater that has penetrated through the soil covering layer or the sewage discharged from the yard itself can be collected under the buried closed covering layer, and its unique drainage function can be used to discharge orderly from the geotextile mat interlayer according to the engineering requirements without forming silt blockage. Possible sliding problems due to saturation of the soil cover with water absorption can thus be avoided.
◎ The geotextile mat can not only drain water, but also discharge the biogas produced by fermentation in the soil, which is especially suitable for application in landfills.
◎ Geotextile mat and HDPE combined application, at the same time can play a good role in protecting HDPE film is not punctured.
