Soil Screening Project, Dorset

Japanese knotweed Soil Screening Project in Dorset

Soil Screening Project, Dorset

We were commissioned by a house building company to remove Japanese knotweed from a seven-hectare site in Dorset.

Project Facts

  • At the time, this was the biggest eradication programme in the UK
  • We found that over half of the site was contaminated by knotweed at various stages of growth
  • The contamination was a result of inadequate eradication treatment by the former owner
  • The site also had a history of mining so had to be stripped back to bedrock in order to stabilise any open mine shafts

TCM cleared this land through the soil screening method – 160,000 tonnes of soil was excavated and processed.

We were able to engineer all of the screened material back into the site, thus creating the correct levels for the proposed development of 390 houses. This also negated the cost of landfill and so avoided the cost of importing clean backfill material.

We completed the work on target, within budget and with TCM’s comprehensive insurance backed warranty.
