Making the earth move for Viridor
Brett Construction's earthworks division will move 600,000m3 of soil in just eight weeks from a landfill site in Southampton to the historic Broadlands stately home estate.
In preparing new cells ready for receipt of waste, the contract will task Brett with installing composite liner systems, protection layers and leachate drainage facilities to protect waterways and land from potential contamination. This will involve 60,000m3 of engineered clay liner, 55,000m2 of plastic liner and 1700m of land drainage.
Using materials on-site, Brett Construction will be screening to produce the gravels for land and leachate drainage schemes. After the cells are full to capacity, they will be capped with clay and restoration soils incorporating an extraction system to pipe gases emitted from the landfill to power generation facilities.
The 600,000m3 of excavated soil will be used in two separate areas of restoration, measuring approximately four acres and six acres, on land owned by Broadlands - the Mountbatten Estate. The soil will be used to protect its landscape setting.
