D-Ecofill & Pr-Ecofill

D-Ecofill (Decommissioning)

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. The Ecofill technology is able to enhance the structural loading and stiffness modulus of agricultural soils to produce the required temporary structures.

This D-Ecofill solution is achieved by analysing soils on a project specific basis and creating a unique, bespoke formulation of D-Ecofill Re-Agents that are added back into the soil to achieve this unique solution.

As with all Ecofill solutions, this eliminates the need for export/disposal of soil off-site and the import of aggregate, which greatly decreases carbon emissions and particulate pollutants compared to traditional construction methods.

Pr-Ecofill (Pre-Treatment)

Our Pre-Treatment (Pr-Ecofill) service is readily available to all projects where clays & subsoils contain high moisture contents.

To achieve ultimate efficiency for the standard Ecofill process, the moisture content levels from the ground stratas’ at the site are tested to ascertain the moisture content range that will achieve the maximum density and structural performance once correctly compacted. This is referred to as the optimum moisture content (OMC) range.

If the natural moisture content of the ground strata at the site is more than 4% above the OMC range, then we can deploy our Pr-Ecofill service whereby we apply & mix our non-corrosive drying agent into the as dug ground. The drying agent will react and decrease the moisture content of the soil. Once OMC is achieved, the regular Ecofill process can begin.

In some rare instances where the ground strata contains an exceptionally high in moisture, stockpiles may need to be formed to allow extra time for the Pr-Ecofill process to reduce the moisture content. Stockpiles are managed to help ensure that water ingress from inclement weather is prevented. To expedite this process further, air-drying can help. For example, on dry or sunny days, the stockpile can be opened-up and turned over, this will help to obtain the OMC sooner.

It should be noted that once air-drying and/or the addition of drying agent has been carried out, unless the material is being laid and compacted in a reasonable time period, stockpiles should be managed to prevent water ingress.

Moisture content will be tested at regular intervals throughout our whole process to help ensure that the optimum performance is always achieved in regard to the ground type and the client’s programme.
