  • Patented across the UK, USA and Canada.
  • Typical savings of 50% compared to other removal methods.
  • As it's an on-site remediation method you may be able to save even more by claiming Land Remediation Tax Relief.

The Xtract™ removal process

Infested soils are excavated using a 360° tracked excavator. The excavation work is supervised by one of our experts to ensure all soil containing viable rhizome, but not more than is necessary, is excavated.

The excavated infested soils undergo a screening process in the Xtract™ machine to separate the Japanese knotweed rhizome from the soil using our patented technology.

Clean processed soils are then immediately ready for re-use on site. Please note that these materials must remain on site. If you intend to dispose of them, then waste legislation applies and the material must be consigned as knotweed infested.

Knotweed removal with insurance backed guarantees

A 5 or 10 year insurance backed guarantee (IBG) underwritten by a syndicate at Lloyd's is issued upon completion. The syndicate is A rated, providing security to the risk averse banks and building societies.

We typically have a one month mobilisation period from receipt of written instructions. In urgent situations we may be able to reduce this subject to our other commitments.

While there are other Japanese knotweed solutions available, we feel our Xtract™ machines offer the most reliable service and at the best cost. Speak to our team of specialists today about your site.
