Contaminated Land Investigation

Two principles guide all the work we do: efficiency and cost-effectiveness. Over the years we have built up considerable experience in applying both to the procedures for investigating and remediating brownfield sites, in liaison with Planning, Environmental Health and the Environment Agency.

Our work here covers the full spectrum of sites, with projects ranging from metal plating works, abattoirs, railway land, petrol stations and garages, to landfills, historic mills, farms and quarries. In fact, any land which has been developed in the past can throw up unexpected contamination such as buried asbestos, backfilled pits or unexplained refuse deposits.

  • On a former landfill at Christchurch we engineered gas protection measures in particularly complex ground conditions, with roads and housing adjacent to a SSSI, on peat marsh and overlying refuse fill.
  • During the geotechnical investigation of a busy hospital A&E entrance in Surrey, unexpected hydrocarbon contamination was identified. So as to limit delays to the construction programme, we rapidly assessed the risk and specified remedial works, completing our work in impressive time.
  • At The Lakes Development in the Cotswolds, we designed and validated remedial works and gas protection measures for a spa complex and individual development plots situated over backfilled gravel pits.
