Japanese knotweed was identified on a site our client wished to develop into five housing plots. The knotweed infestation was located to the rear of three of the proposed plots, totalling a visible area of approximately 128m2.
The neighbouring site also contained two large infestations of Japanese knotweed, which had been previously treated with herbicide. Therefore, a root barrier was required to ensure that the knotweed didn't encroach onto our client’s site, as this could impact the lenders decision when offering finance on the five plots.

Our client required Japanese knotweed to be removed from 6 locations across a disused landfill which was being converted to a solar farm. Upon surveying the site, 5 additional stands of Japanese knotweed were identified which were incorporated into the proposal for the site.

Our client wished to develop a site by building two properties and a driveway. Unfortunately, an infestation of Japanese knotweed was discovered, which put a halt to development plans.
After conducting a site survey, it was established that the visible knotweed was approximately 60m2, with a smaller 4m2 infestation on the neighbouring property.

Environet UK Ltd is the preferred knotweed specialist for a rapidly expanding food superstore chain. Having secured planning permission, tackling the six areas of knotweed amounting to over 100 sq m of affected land was next on the agenda.
Environet assessed the site in December 2016, estimating there to be some 200 cu m of infested soil. The “dig & dump” option whereby all infested soils are excavated and consigned to landfill was rejected due to cost (circa £50,000 + VAT) and for environmental reasons.

Our client was looking to redevelop a site which had a large Japanese knotweed infestation. The knotweed problem needed to be resolved fast to ensure that the site development stayed on track. There were a number of constraints to the site including access issues, services and a live railway in close proximity.

A site in Sheffield was being redeveloped into a car park, but there was a problem: Japanese knotweed. To make it more complicated, the knotweed was located on a bank between the site and a main-line railway track with a HV electricity cable running through it.

A herbicide treatment plan was put in place to treat Japanese knotweed which was discovered on site. The client did not have any plans to develop, so this was the most cost effective method for them.
The client initially instructed Environet to carry out herbicide foliar spray on one area. Further instructions came in 2012, 2013 and 2014 for further areas on site. In total our client had 18 stands of established Japanese knotweed.
