Geonet Fabric: Drainage Performance and Engineering Applications
Geonet fabric provides an efficient drainage layer for civil, environmental, and geotechnical projects. For contractors, distributors, and project buyers, understanding its drainage capacity, structure, installation conditions, and long-term performance is important before selecting a product for landfills, retaining structures, roads, mining sites, or other drainage systems. What Is Geonet Fabric and How Does It Work? A geonet is a polymeric drainage material manufactured with intersecting ribs that form continuous channels. These channels allow water, leachate, or gas to move laterally through the material. High-density polyethylene (HDPE) is commonly used because of its chemical resistance and durability. In many projects, a geonet is combined with a nonwoven geotextile on one or both sides. The geotextile acts as a filtration and separation layer, while the geonet core creates the drainage pathway. This structure is commonly called a drainage geocomposite. For projects requiring a...
