ENVIROSOIL (Remediation) Limited is a national ground improvement and remediation specialist, with bases in the South East, West Midlands and southern Scotland. It offers engineered material replacement and remediation solutions to land developers and contractors alike.
Large UK construction sites have benefited from this technology for at least ten years. On a small scale the process can be prohibitively expensive; typically 3000m³ is considered by contractors to be the minimum commercially viable quantity.
Envirosoil own a small, compact, state of the art soil stabilisation machine, which eliminates this cost problem; presently we are the only contractor in the UK to possess such a compact plant. Therefore we are able to consider sites that require as little as 250m³ of material to be processed.
Government legislation requires the construction industry to reduce its dependance on primary aggregate extraction, and implement the Landfill Regulations regarding dig and dump techniques. Reusing site based materials that have been given enhanced engineering properties is a solution that can not be overlooked.
BENEFITS INCLUDE
Cost savings of up to approximately 50% when compared with traditional methods, ie muck-away and import replacements.
Reduced and accelerated program times (compared to traditional muck-away).
Reduced lorry movements on surrounding roads (typically 2000 per site if the process is fully utilised).
Enviro-Lock prevents the need for 'dig and dump' of contaminated material. With the government's enthusiasm for reducing usage of landfill sites, this process is actively encouraged by Local Authorities and the Environment Agency (mobilisation periods apply).
Contaminated in-situ materials (typical contaminants: heavy metals, hydrocarbons) can be locked into the host material via various binder additions. Avoiding dig and dump in this way prevents the spread of contamination outside of a site's boundary, an aspect that the Environment Agency are keen to promote. The locked material is also monitored for reduced permeability; this reduces leachate contamination.
BENEFITS INCLUDE
Cost savings in the order of 50%-75% when compared with traditional methods, (ie muck-away and import replacement).
Reduced and accelerated program times (compared to traditional muck-away).
Reduced lorry movements on surrounding roads (hundreds per site if the process is used fully).
