Diadrain-25H
Extensive roof. The special design of diadrain-25H allows the maximum amount of water to be retained, which is gradually dstributed to the plants, while also allowing for proper ventilation of the root system, and is best suited for the dry-heat conditions of the Mediterranean climate during the summer months. The high strength of the drainage diadrain-25H makes it suitable for use not only for no-access roofs, but also for roofs with footfall traffic, and can withstand the load of structures such as hardwood decking and more.
