four 25mm Drainage and Reservoir Board Perforated drainage board mounted to slow down the discharge of rainwater. Also retains a particular quantity of rainwater forever to the roof, that's drawn back in to the planting elements via evaporation to help drinking water the living elements of the Blue-green roof. Could be filled with gravel chippings to offer structural balance inside of a podium software.
