C&F Japanese Knotweed Removal

What Is Involved In Excavating Japanese Knotweed?

Excavation of Japanese Knotweed material is normally a last resort but is increasingly popular with developers because of the reduced time scales involved.

Environment Agency guidelines on the excavation of Japanese Knotweed indicate that to be sure of total removal of the weed excavation needs to be to a depth of 3m and 7m horizontally from weeds on the surface. Excavation depth would normally decrease towards the edges. Site conditions and careful inspection of the excavated material will often allow for this excavation of Japanese Knotweed material to be reduced and consequently the disposal costs associated with it.

Dumping of Japanese Knotweed material is extremely costly and the amounts of material invovled for a complete excavation can be huge.

What Are The Benefits Of Excavating Japanese Knotweed?

Normally the main benefit is speed of dealing with the problem as well as completely removing the problem of Japanese Knotweed from the site. It also allows for the installation of geotextile membranes that give protection against the spread of the weed.
