Stockpiling and Spray

Quotations available upon request

Otherwise known as 'bunding', this method involves excavating contaminated soils (containing Japanese Knotweed root material) and transferring them to a predesignated area of the site that will remain undisturbed.

​

This area will be dug to a shallow depth and lined with a geo-textile membrane onto which the contaminated soils will be placed.

​

The Japanese Knotweed will then be encouraged to grow where a systemic herbicide treatment can be applied to the plant to further control it.

​

This does not remove the Japanese Knotweed form the site but does enable development works to proceed whilst treatment takes place elsewhere. 

​

An Invasive Species Management Plan will accompany any treatment process.
