A 2-dimensional geonet, also known as a drainage net, is a type of geosynthetic material designed primarily for drainage applications in civil engineering, construction, and environmental projects. It consists of polymeric ribs arranged in a two-dimensional grid pattern, forming a net-like structure. This configuration allows for effective fluid and gas drainage, making 2D geonets particularly useful in applications such as landfill liners, road and railway construction, retaining walls, and tunnel drainage.
