1. After the geotechnical mat is combined with the non-woven geotextile, it can collect rainwater that has penetrated the soil cover or the sewage discharged from the yard itself under the buried closed cover layer, using its unique drainage function, in accordance with the requirements of the project Discharge in an orderly manner from the interlayer of the geotechnical mat without forming siltation. Therefore, possible sliding problems caused by the saturation of the soil cover layer with water absorption can be avoided. 2. The geotechnical mat can not only drain water, but also discharge the methane produced by fermentation in the soil. It is especially suitable for application in landfills. 3. When the geotechnical mat is combined with HDPE, it can also protect the HDPE membrane from being punctured.
