Environmental clean-up and remediation technologies by CTSL

Unique in our sector, by using image modelling our teams undertake surveys using high-resolution 3D scanning, utilising images for pre-condition surveys and demonstrations of final reinstatement to showcase finished results.

Loss adjuster clients access walk-throughs in order to appraise properties and work that may be required without needing to visit the site, making an immediate cost and time saving for the insurer. The use of this technology also precludes claims for betterment and compensation for pre-existing damage.

With greater data protection compliance, document recovery access and paper-saving environmental benefits, our password-protected bespoke system allows our UK-wide teams to safely share full reports, photographs and inspection notes directly from site with clients and other members of the CTSL team.

Wherever teams are, our systems encourage collaboration and excellent communication.

CTSL has embraced video calling, which has proven to be an excellent way for site teams to communicate with clients, directors and project managers effectively and again avoiding the need for unnecessary and costly site visits. Problems and issues can be appraised and dealt with remotely, allowing the site team to get on with the job.

Used either on its own or in combination with chemical oxidant treatments, SVE can be used in certain circumstances to treat residual contamination in-situ. Dependent on factors such as levels of contaminant impact and soil type, SVE is useful as an alternative where removal of contamination is impractical due to structural constraints, for example residual contamination beneath property foundations.

The SVE process transfers volatile organic compounds (VOCs) from the solid phase (sorbed onto soils) into the gas phase and extraction of VOCs, thus enhancing the remediation.

Groundwater is a protected resource and remediation is required where the groundwater becomes polluted as a result of a pollution event or spill. Remediation is achieved either by removing the pollutant from the groundwater, typically by removal of contaminated groundwater and processing through a suitably designed treatment system to recover the pollutant, or by converting the pollutant to harmless by-products via chemical treatment.

Different technologies are deployed dependent on the contaminant, which may be either less dense than water (floats on groundwater), denser than groundwater (sinks in groundwater) or highly soluble (mixes with groundwater).

Bespoke treatment systems can be designed by our team suitable to the project, and our highly experienced remediation engineers are on hand to monitor and maintain these systems during treatment. For remote locations, data logging and telemetry systems are available to limit the number of visits to site, thereby reducing costs.

Chemical oxidant injections into soils are a useful in-situ remediation technique where contamination remains in areas where removal is complex, for example beneath property foundations. Injection of the chemical oxidant into contaminated soils results in a chemical reaction which breaks down the contamination in-situ.

The technique can be used in combination with SVE to extract vapours between chemical oxidant treatments.
