CTSL Remediation

Our in house team includes engineers and geologists with experience in desk-based research, the design and implementation of ground investigation and the successful implementation of remediation strategies.

Our Remediation Services tend to be focussed on the insurance sector for whom CTSL act as a ‘First Responder’ in cases of oil spills. We have the capability to react quickly and appropriately to contain a spill and to address the implications of any oil that has been lost. Once a spill has been contained CTSL will design, implement and validate the remedial works to ensure that the consequences of a spill are dealt with in an appropriate and cost-effective way.

In cases where excavation is considered to be the most cost-effective remedial approach, a range of possible destinations for the excavated material will be considered, including the use of soil-treatment sites to avoid consigning waste to landfill and associated landfill tax payments.


Heating Oil Spills

CTSL’s remediation business has principally developed in the field of oil spillages with a wealth of projects completed in domestic properties, commercial premises and vehicle refuelling stations.


Impact to drainage, groundwater and surface water – external spills

  • Oil tanks are usually located externally and a spill can discharge into buried ducts or drains. These drains often discharge into streams or ponds, leading to oil contamination of these surface water features. When water resources become contaminated, there is a statutory obligation to involve regulators such as the Environment Agency (in England) or Natural Resources Wales.

Impact to building materials – internal spills

  • Building materials such as bricks and blocks readily absorb kerosene and therefore, remediation requires the removal of the contaminated material and its replacement with new building materials. These remedial works involve a great deal of preparation to ensure the structural stability of the property. CTSL recognise that these works are highly intrusive and that in domestic cases, can be very stressful. The client-care element of what we do is therefore as important as the technical skill and expertise required to undertake the remediation itself.

Other Contaminants

On the basis of our success in cleaning up oil spills, CTSL are increasingly being asked to look at the remediation of more diverse contaminants e.g. metals and asbestos.
