Green Roof Drainage Board



Green roof drainage boards are the ideal rooftop drainage solution. This mat enables drainage of excess water without the risk of clogging.

Each 3D mesh drainage board provides great compressive strength and consistent water flow. This makes roof drainage uniquely able to continuously discharge water under load. The geocomposite filter material around the drainage board is a separation layer that helps roof membranes to breathe and also filters dirty water passing through the green roof drainage system.

Great for applications such as: green roofs, rooftop gardens, as a protective layer over roofing membranes, and as an underlayment for pavers.
