Asbestos In Demolition Rubble

VertaseFLI was contracted by Wakefield and District Housing Limited through Environmental Consultant Robson Liddle, to undertake works to remediate asbestos impacted demolition.

A former Public House constructed in part with Asbestos Contaminated Material (ACM) had suffered from demolition malpractice, resulting in a significant volume of demolition arising containing asbestos, which had been negligently used to backfill a cellar structure.

Project Value



6 weeks

Services Provided

Handpicking and disposal of visible asbestos fragments, breaking out concrete and excavation of underlying asbestos soil to facilitate the redevelopment, reuse of impacted soils under CL:AIRE Code of Practice, crushing and processing of hard materials.

Further Information

The works involved the establishment and management of an asbestos control zone (accessed and egressed via a decontamination unit) in order to sufficiently protect site operatives and the public. A hand picking
exercise was undertaken to remove surface ACM, prior to the excavation of impacted demolition arising.
The ACM from the demolition arising was segregated and disposed of offsite. The handpicked demolition arising was screened, crushed, tested and used to create a suitable development platform for residential properties.
The works were carried out under the CL:AIRE Code of Practice for the reuse of waste on site. Strict health, safety and environmental practices were adhered to at all times and were reinforced with the full time presence of a specialist independent air analyst. Asbestos fibres in the air were
measured on a full time basis and personal monitoring on numerous site workers was undertaken both within and external to the control zones.
The remediation works were complicated by the fact that the ACM materials had been used to backfill a 4m deep cellar structure and the controlled excavation of this proved challenging, with access issues and constant dust suppression. In addition to the asbestos, the demolition malpractice also posed uncertainty over the presence of live services which had to be hand dug and identified prior to excavation works. The works were completed and the site handed over to the client for redevelopment in a 6 week programme.
