Former Bakelite Works, Southend-on-Sea

Client: Knight Group
Date: 2015—16
Nature of works: Asbestos in Soils and Bioremediation
Contract Value: £495K

Soilfix were contracted to carry out soil remediation at the former Ecko Bakelite Works in Southend-on-Sea.

The Challenge
This 10Ha former factory presented a variety of contamination issues, including a large area of free-product hydrocarbons, stockpiles of demolition material containing asbestos cement (AC) fragments and AC contaminated air raid shelters.  During slab breakout, the Main Contractor identified significant deposits of asbestos insulation board (AIB) and AC fragments within made ground soils and infilled basements / pits.  Off-site disposal would have rendered the proposed residential scheme commercially non-viable.

Our Solution
Soilfix implemented a sustainable and cost effective and solution bin conjunction with RSK Environment, all in accordance with a Materials Management Plan (MMP) fully in accordance with CL:AIRE Code of Practice (CoP) which included:

  • 5,000m3 soils subjected to targeted excavation from hydrocarbon impacted source areas;
  • Ex-situ bio-remediation treatment of 3,000m3 diesel saturated soils, successfully treated for re-use as sub-capping fill;
  • 75,000 litres of free-product impacted waters recovered during remedial excavations;
  • 24,000m3 made ground containing AIB & AC fragments subjected to modular processing to segregate visible fragments as Licensable Works. Soils utilised as sub-capping fill or removed off-site as de-categorised Non-hazardous waste;
  • Targeted excavation and disposal of soils containing asbestos insulation (lagging);
  • Total 51 tonnes of segregated ACMs removed off-site as Hazardous Waste in accordance with Duty of Care; and,
  • Groundwater abstraction wells (up to 50mbgl) decommissioned in accordance with EA protocols.

All works were completed fully in accordance with the Control of Asbestos Regulations (CAR) 2012.  In spite of the significant unforeseen volume of made ground containing asbestos fragments, delays to the developer’s overall construction programme was reduced to a practicable minimum.  Modular processing of asbestos contaminated soils saved over £6.5million on the cost of removing materials off-site.
