An HDPE dimpled drainage board with drainage holes – suitable for green roofing.
Proteus Pro-Living® DR20 is a heavy duty HDPE dimpled drainage board with drainage holes – suitable for green roofing.
Proteus Pro-Living® DR20 provides an air gap to allow free drainage of water and slows water runoff but prevents waterlogging.
Water held in reservoir cups can be drawn up back into the substrate in dry periods. Excess water dissipates through the perforations between each cup and through the drainage channel out into the outlet
