Ecofill can provide our “R-Ecofill” solution,  a complete process for the treatment of contaminated soils. This involves us processing the contaminated soils with specially formulated Ecofill binders. 

The binder(s) will treat the contaminated soil through the process of solidification or stabilisation. Contaminants will therefore either be encapsulated, have their leachability reduced to safe levels or become chemically changed therefore reducing toxicity or mobility.

Ecofill can formulate bespoke proprietary binders to the contaminants present at the job site as determined in from the site investigation data. This helps ensure that the optimum outcome is obtained on a site by site basis in terms of sustainability, performance and cost.

In addition, Ecofill has the potential to unlock the UK’s 21,000 Brownfield SitesOften in prime locations, these stalled sites are now becoming much more commercially viable due to the cost-effective R-Ecofill offering providing attractive land opportunities for both private developers and the UK Government alike. 

This is land acquisition made easy.


To comply with the relevant statutory requirements for the treatment of contaminated land, Ecofill can provide the client with a full package, which includes the following:

A document detailing the objectives, methodology and procedures of the proposed treatment works. The treatment works must remove the risks to human health and the environment either by physically removing the contaminated material or installing barriers to make the contamination inaccessible. The completed process must make the site suitable for use and remove future risk of any remaining contamination becoming mobile. Before any works commence, the treatment strategy must be submitted.


After the treatment strategy has been reviewed, samples are taken from site to an independent laboratory where mix design trials can begin. This will include the formulation of mix designs to what addition rate of binder(s) is required to successfully treat the contaminated soil. The results of independent stabilisation trials are submitted to the regulatory authorities for statutory approval as part of the strategy with the necessary notification to deploy under an appropriate environmental permit.


Legally required for projects over 1000 cubic meters.


This is carried out on-site whilst treatment with the required mix design is taking place. This is a requirement of the permit and the regulator.


Following completion of the works that were agreed in the treatment strategy, a validation report must be submitted to the Planning department and a Verification report submitted to CL:aire. These documents will demonstrate that the works have been carried out satisfactorily and targets have been achieved. These will include documentary evidence for processes carried out during the treatment work to prove it meets the appropriate targets.
