Ecofill is a brand-new ground technology which processes inert, non-hazardous and hazardous clays & subsoils into structural fills which meet the national specification for highways and earthworks.
The Ecofill solution includes an on-site, ex-situ technology using state of the art machinery and non-corrosive, bespoke proprietary binders.
Our services include materials design, production, testing and validation, all of which meet the National specification of the Design Manual for Roads and Bridges (DMRB) and is fully accredited by our independent industry partners.
By reducing the traditional requirement for the disposal of spoils to landfill and the import of aggregates Ecofill offers a sustainable and cost saving solution.
Significant Cost Reductions
Reduced Carbon Footprint
Increased Carbon Handprint
Improved Standards & Practices
Ecofill also provides an opportunity to engage in regenerative & responsible sustainability whilst further enhancing your own goals and commitments to address the current climate crisis.
Ecofill aims to be the new norm in all Construction & Civil Engineering projects including residential, commercial, Industrial, infrastructure and the renewable energy sectors providing significant cost reductions whilst also helping developers to engage in regenerative and responsible sustainability.
Our products are suitable for use on virtually all permanent earthworks structures including
Adoptable roads and footpaths
Flood defences
Car parks, Loading Bays & Storage Areas
Laydown and hardstanding areas
Railway Embankments
Our Materials Management Plan will form the backbone of operational control, providing the ability to demonstrate materials suitability for reuse, both in terms of geotechnical performance for earthworks reinstatement and environmental compliance.
Our end products are designed and produced to meet all national specification requirements and performance levels.
Meeting and surpassing minimum structural requirements of 15%+CBR for Capping Layer, 30%+CBR for Sub-base Layer & 100%CBR for our HD Layer (Heavy Duty Surface Layer)
The Ecofill enhanced structural fills will be designed, produced, tested and validated all to the relevant specifications of the Design Manual for Roads and Bridges (DMRB) which are fully accredited by our independent industry partners.
The Ecofill process and by its very nature is ideal in the construction & decommissioning of temporary structures such as haul roads and compounds.
Typical applications and structures produced using the Ecofill process include:
Haul roads & access roads
Compounds
Haul roads & access roads
Working platforms (piling mats & crane pads etc)
Collaborating with our partners, Ecofill can design and build working platforms such as piling mats and crane pads which are produced to BRE 470 and/or Temporary Works Forum TWf2019: 02.
Material is sampled from site and tested at the laboratory.
Here we have the ability to formulate a binder specific to any site / ground type and furthermore, we can achieve the following:
If the site is contaminated, the mix design study will also demonstrate the unique and specific Ecofill binder design required to either encapsulate or retard the leachability of the site contaminants to safe levels.
This ensures full environmental compliance is achieved for end use.
Ecofill can provide our “R-Ecofill” solution which is a complete remediation process for contaminated soils. This involves us processing the contaminated soils with the Ecofill proprietary binder.
The binder will remediate 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 the remediation strategy. This helps ensure that the optimum remediation outcome is obtained on a site by site basis in terms of sustainability, performance and cost.
To comply with the relevant statutory requirements for remediation of contaminated land, Ecofill can provide the client with a full remediation package, which includes the following:
A document detailing the objectives, methodology and procedures of the proposed remediation works. The remediation 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 remediation must make the site suitable for use and remove future risk of any remaining contamination becoming mobile. Before any works commence, the remediation strategy must be submitted.
After the remediation 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 remediate the contaminated soil. The results of independent stabilisation trials are submitted to the regulatory authorities for statutory approval as part of the remediation 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 remediation 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 remediation 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 remediation targets have been achieved. These will include documentary evidence for processes carried out during the remediation work to prove it meets the appropriate targets.
Our unique D-Ecofill process is widely available to decommission temporary structures such as haul roads & compounds once they have reached the end of their design life.
This regenerative solution transforms the Ecofill structures back to their original pH and nutrient status.
For example, this is particularly important in the case of a farmer’s field where the subsoil is required to be returned to its original condition to allow the future growth and harvest of crops.
Our Pre-Treatment (Pr-Ecofill) service is readily available to all projects where soil types and ground strata consistently offer overly high moisture content.
To achieve ultimate efficiency for the standard Ecofill process. Moisture levels from as dug ground or stockpiles need to be kept within pre-determined moisture levels.
Stockpiles will be tracked and sealed to prevent water ingress from inclement weather and will be tested for moisture content or MCV.
If stockpiles have a high moisture content (4%+ of OMC) then, if applicable, on dry and/or sunny days the stockpile can be opened-up and turned over to reduce moisture content.
In addition to air-drying high moisture content subsoil, our Pre-Treatment (Pr-Ecofill) service can be deployed whereby a non-corrosive drying agent can be mixed into the subsoil.
The drying-agent will react and decrease the moisture content of the soil.
It should be noted that once air-drying and/or the addition of drying agent has been carried out, stockpiles should be sealed again to prevent water ingress from future inclement weather.
