Horizontal Drainage Ausdrain™
30mm Drainage Cell creates a permanent non-clogging void between the concrete slab and the soil profile that will not collapse or distort. The 30mm void enables a direct flow of water to designated outlets avoiding the risk of water build-up and penetration. The large surface and capacity void space enables superior drainage efficiency compared to the small voids created by using a gravel system. The lightweight nature of this product reduces weight on the structure by 98% over gravel making it the perfect choice for roof gardens and podiums. In addition, there is a 5:1 reduction in the drainage medium height allowing greater soil depth and scope for plantings.
The drainage cell also acts as a membrane protection layer, however, depending on the membrane it is recommended to use a suitable protection board between the membrane and drainage cell layer. AUSDRAIN™ 30mm Drainage Cell is available in 500x500mm modules for smaller areas, 1000 x 1000mm interlocked panels for ease of installation on large area projects.
