Envirotreat Technologies Ltd was commissioned by Thomas Vale to provide support services for a new school development close to the centre of Coventry. The site was previously occupied by a hospital – the hospital buildings had been demolished and there were substantial volumes of stockpiled demolition rubble remaining on the site prior to commencement of redevelopment works. Thomas Vale wanted to maximise the reuse of stockpiled material on site where possible (and to minimise unnecessary and costly offsite disposal of potentially hazardous and non-hazardous soils / materials). Envirotreat carried out analysis of the stockpiled material which was contaminated to varying degrees by asbestos and petroleum hydrocarbons. Envirotreat developed a remediation strategy for the site which was approved by the regulatory bodies. The strategy involved a ‘watching brief’ and analytical testing of soils / stockpiles at key stages during the enabling works – this enabled a practical and cost-effective remediation approach to be implemented whereby geotechnically suitable material was retained on-site and only inert (made ground) and natural soils were disposed of offsite (resulting in significant time and cost savings to the client). Additionally the works involved the management and control / treatment of Japanese Knotweed present on the site embankment.
