Cognition carried out large-scale remediation of extensive asbestos contamination at a former clay pit and tile factory in Surrey. Asbestos contamination emanated from the old asbestos clad/roofed buildings, many of which had been demolished with debris buried on site. Cognition’s successful processing and removal of the asbestos has meant that the material is now suitable for re-use on site.
Cognition carried out large-scale remediation of extensive asbestos contamination at a former clay pit and tile factory in Surrey. Asbestos contamination emanated from the old asbestos clad/roofed buildings, many of which had been demolished with debris buried on site. Cognition’s successful processing and removal of the asbestos has meant that the material is now suitable for re-use on site.
Although the asbestos work could be carried out as non-licensed work, the volumes were significant and therefore 'notifiable' under the Control of Asbestos Regulation 2012. Asbestos was mainly present as bonded chrysotile in roof sheets and rainwater pipes and gullies. Broken sheets littered the ground in the location of the former factory buildings with broken fragments buried in a landfill in the southeast corner of the site.
Cognition adopted a methodical, systematic approach with safety as a high priority. The working areas were cordoned off from the main site with access through a mobile decontamination unit. During site works, air fibre monitoring was undertaken to ensure fibres did not exceed the lower control limits, and materials were dampened to prevent fibre release with all operatives wearing appropriate PPE.
After treatment, all excavated material (over 3000 m3 in more than 20 stockpiles) was cleared for re-use as part of the cut and fill works now beginning as part of the second phase.
