Spoil to Soil Services
Spoil to Soil is our controlled method for managing knotweed-affected soil on site. Contaminated soil is carefully screened under supervision, with materials retained and managed in line with project and compliance needs.
Why choose Eco Control Solutions for Spoil to Soil services?
Our Spoil to Soil method provides a controlled alternative to removing all knotweed-contaminated soil from the site. Contaminated material is carefully separated under supervision, with selected material managed appropriately under strict containment protocols.
It’s a practical way to reduce waste, minimise haulage, and keep more material on site where conditions allow.

Controlled excavation and screening
Our team excavates the affected soil and separates out any material containing knotweed rhizomes. Only soil deemed suitable for restricted on‑site placement is retained.
Records and compliance support
You’ll receive full documentation detailing what’s been excavated, screened, and reused. We can provide optional Insurance-Backed Guarantees and revisit the site to confirm ongoing compliance.
Residential property
Japanese Knotweed Excavation and Removal in Residential Property
Our client was the owner of a residential property with very limited access to the rear of the house, which comprised of a decked terrace overlooking a long, narrow garden, which sat several feet lower than the house. There were two infestations of Japanese Knotweed present within the garden. The first was growing underneath and around a garden shed, the second was growing in a rockery that had previously been a pond. The client opted for a full excavation and removal, rather than a treatment solution, as they had plans to redesign the garden.
