HyGro DB 50

A prefabricated product that consists of a formed and perforated core covered with a soil filter layer and a fabric protection layer. The filter fabric is securely bonded to prevent soil intrusion into the core flow channel while allowing water to freely enter the drainage core. Sheet drains allow water entry from one side and are typically used to collect and re-direct water from below the growing medium of a green roof system.
