composite drainage network reverse filtration railway tunnel subgrade anti-seepage filtration hdpe geonet flexible

The product is manufactured using high-quality HDPE raw materials, which offers excellent flexibility and tensile strength. It also possesses characteristics such as corrosion resistance, aging resistance, and UV resistance. The three-dimensional mesh core structure forms continuous drainage spaces, enabling water to drain quickly. The surface geotextile serves a filtering and reverse filtering role, preventing sediment from entering the drainage channels, maintaining the long-term unobstructed drainage system.

The composite drainage mesh is light in weight and easy to construct, allowing for easy cutting and laying according to the engineering requirements. It can also be used in combination with other geotechnical materials to enhance the overall anti-seepage and drainage performance.
