Spoil To Soil

Spoil to Soil Technology enables ECS to provide the Client with guaranteed clean soil that can be used to back fill excavations with the additional reassurance of an approved residual persistent herbicide applied which ensures that even the smallest rhizome particle is left non viable to cause future re-growth.

By using innovative plant that has been tailored for the purpose, we have been able to keep the cost of this methodology to below that of existing mechanical techniques such as the Dig & Dump. On average the amount of controlled waste taken off site to a registered landfill is upto 40% less than the Dig & Dump mythology and cost savings to the client are also made by reusing the soil as clean backfill.

This method works by mechanically separating the Japanese Knotweed rhizomes from the soil with ECS’ specialist equipment and can be very effecting in the correct conditions.

This methodology is site dependent and there are certain soils which are not suitable for mechanical reasons.
