The three-dimensional double composite drainage network (also known as a 3D geotextile drainage board, tunnel drainage panel, or drainage mat) is an advanced geosynthetic material composed of a high-strength three-dimensional plastic mesh core. This core is securely bonded on both sides with permeable geotextile layers (or alternatively, one side with geotextile and the opposite side with an impermeable geomembrane for specialized applications).

This innovative structure combines efficient drainage performance with superior filtration capabilities, making it ideal for civil engineering applications such as tunnel waterproofing, foundation drainage, landfill leachate collection, and slope stabilization. The unique 3D mesh design provides exceptional in-plane flow capacity, while the geotextile layers prevent soil clogging and ensure long-term drainage efficiency.
