Details on the landfill cell

The Inkerman site contains dedicated disposal cells for low level contaminated waste (LLCW). The current cell is single composite lined and separated by constructed bunds from general waste cells. The LLCW cell is also located around the perimeter of the landfill stage as part of the site design. The LLCW cell is constructed with a 600 mm compacted clay liner overlain by a geodrain leak detection layer. A geosynthetic clay liner (GCL) layer and then a High Density Poly Ethylene layer is then overlain by a 300mm deep drainage aggregate placed on a cushion geotextile.
