Remedial Works

  • The oil tank and boiler unit were disconnected and removed. A temporary heating supply was set up.
  • The oil tank base was broken out and removed.
  • A section of concrete footpath in the back garden was broken out and removed.
  • The identified contaminated soil and fill material was excavated and removed.
  • Specialised treatment solutions were applied to the base and sides of the excavation to treat residual contamination at depth.

Reinstatement Works

  • The excavation was backfilled with granular sub-base backfill material and compacted at regular intervals.
  • A new section of concrete footpath was poured in the back garden which was also extended into the boiler and oil tank base.
  • The oil tank was reinstated on the new concrete base.
  • The boiler unit was reinstated on the new concrete footpath/ base (see Photo 13) and the heating system was recommissioned.
  • Topsoil and lawn seed spread on the previously disturbed soft landscaping in the back garden.
  • The site was tidied prior to demobilisation.
  • A final sampling exercise was undertaken to examine soil quality at the previously affected areas.
