Removal of Artex Containing Asbestos

Prior to undertaking works to widen the eastbound carriageway on the A303, a pre-demolition asbestos survey was commissioned by the Client.  Chrysotile asbestos was identified within the textured coating (Artex) on the walls in a subway beneath the A303. VertaseFLI was instructed by the Client to remove approximately 300m² of Artex from within the subway to prepare for the hydro demolition works.  The hydro demolition works were necessary to cut recesses into the walls and ceiling of the subway so structural steels could be installed to take the extra load of the traffic above.  To enable access to the works, the subway was closed and a bus service provided to transport pedestrians. Due to the nature and type of asbestos, the works were non-notifiable. In addition, due to the duration, extent and chosen method of removal (wet work), the operation was considered low risk, however control methods were in place to further reduce risks.

Further Information

An initial survey was undertaken to assess the condition of the textured coating. Due to the damp conditions of the subway walls, there was extensive damage to the Artex, therefore VertaseFLI advised the Client that the Artex should be removed in its entirety. Works undertaken included:


  • Construction of semi enclosures along subway sections as works progressed. 
  • Personal and background air monitoring during the works.
  • Textured coating remover applied to the surface of the walls to soften the Artex to a pulp allowing it to be scraped off. This method significantly reduced if not eliminated the release of any fibres. 
  • Artex was scraped off the walls onto a ground sheet, where it was further wetted before being double bagged in asbestos bags.
  • Following the removal of the Artex, a sealing compound was applied as a precaution. On completion, samples were taken from the walls by an independent surveyor; the analytical result came back negative for asbestos.
  • Independent analyst undertook air monitoring to confirm that asbestos fibres were not present within the subway allowing it to be reopened to the public
