Geonets are specialized geosynthetic materials used in civil engineering and environmental projects. They consist of a network of interconnected strands that create a three-dimensional structure, allowing for the efficient drainage of water and the movement of gases. Geonets are often used in applications like landfill design, where they help manage leachate and prevent water accumulation. These materials are typically made from high-density polyethylene (HDPE) or polypropylene, making them durable and resistant to chemical degradation. By providing a pathway for fluids, geonets enhance the performance of systems like drainage layers and geocomposites, ensuring better stability and longevity in various construction projects.
