The raised projections on an HDPE Dimple Drainage Board create continuous spaces between the board and the installation surface. These spaces form drainage channels through which water can travel towards collection pipes or drainage outlets. Unlike ordinary flat protective sheets, the dimpled structure provides a dedicated pathway for water movement. The design also helps distribute external pressure across the board. Depending on the product specification and installation arrangement, it can support drainage behind vertical walls and beneath horizontal surfaces. Proper placement is essential because blocked outlets, incorrect overlaps, or unsuitable filtration arrangements may reduce drainage performance.
