The project comprised of capping works to Cells 1A and 1B, which consisted of trimming the waste, placing a 300mm regulating layer followed by a 1mm LLDPE geomembrane that was protected by HPS4 protector and this was covered by a 1000mm layer of seeded restoration soils.

The cell works comprised of excavation to bring the cell to formation. The cell formation was then overlain by 1000mm mineral clay liner covered by a 2mm DPE membrane and HPS 11 geotextile. This was then covered by a 300mm thick layer of leachate drainage gravel into which, leachate drainage pipes were placed that led to a constructed leachate extraction and monitoring point.

A diversion ditch was also inserted around the works.
