Our pack of 8 Nero Drainage Cells covers an area of 2.4 square metres. Each individual cell measures 600mm (L) x 500mm (W) x 30mm (D)Our Nero Drainage Cells, manufactured from recycled plastics, have a wide variety of uses. They are lightweight and easy to transport and carry but have a high load-bearing capacity of up to 150 tonnes per m2.Key uses for Nero Cell are as follows;In conjunction with soakaway crates, to increase the soil contact area, ideal for soakaway applications in heavier soilsAs an underdrain, to capture and discharge rising groundwater and eliminate the hydrostatic build-upAs a liner for planter boxes and roof gardens, removing excess water and retaining water in the cup structure for passive irrigation in drier periods.To create a horizontal drainage layer under paved areas and podium slabsIn streetscaping applications, in conjunction with Rainsmart soakaway cratesIn sports field drainage applications, in conjunction with Rainsmart soakaway cratesAs a capillary break in saltwater environments, protecting planting from the destructive forces of rising saltwater.Nero Celland#039;s unique cup structure holds water for passive irrigation in drier periods, whilst any excess water is removed by the multi-directional vortex flow through the drainage cell. Nero creates a perfect void for the draining of water, as there is no obstruction to the horizontal flow of water inside the cell structure.Nero Cells are a lightweight, efficient equivalent to traditional gravel drains.
