Yes, specially selected HDPE Dimple Drainage Boards can be used in green roof assemblies. They help manage excess rainwater and irrigation by creating drainage spaces beneath the growing medium. This arrangement supports controlled water movement towards designated outlets and can help prevent unnecessary water accumulation within the roofing system. Depending on the design, filtration layers may also be required to prevent soil particles from entering and blocking the drainage channels. Green roof applications need careful consideration of load capacity, water retention requirements, root protection, and waterproofing compatibility. Selecting the correct drainage board is important for maintaining the overall performance of the roof.
