Ausdrain’s 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 planter boxes, roof gardens and landscaped podiums. In addition, there is a 5:1 reduction in the drainage medium height allowing greater soil depth and scope for plantings.
The high compressive strength of Ausdrain’s 30mm Drainage Cell enables materials to be delivered directly by truck and machinery to spread sand and soil once a minimum of 300mm 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, it is recommended that a layer of protection board be placed between the membrane and drainage cell.
Our 30mm Drainage Cell is supplied in interlocking 1200mm x 1200mm panels, comprising 4 pieces of 600mm x 600mm. The panels are ideal for large areas but can easily be divided or cut for smaller areas, curves or edges.
