Drainage Cell

Ausdrain 30mm Drainage Cell

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 AUSDRAIN™ cell is the strongest product available on the market with a university tested compressive strength up to 1500 kPa. This allows materials to be delivered directly by truck and machinery to spread sand and soil once a minimum of 400mm has been placed over the drainage cell/ filter fabric layer. Filter fabric is placed over the drainage cell and is supplied in roll widths of 2m and 4m. The fabric combined with a layer of washed sand, filters the water eliminating staining caused by gravel, stone and soil materials.

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.
