Knotweed on the site next door? Protect your property with a ground barrier.

It is common for knotweed to become established in those areas of a site not in active use and so the perimeter is often where it can be found.  Nine times out of ten this will mean the knotweed has transgressed the legal boundary.  In such circumstances, it is ok to erradicate the knotweed on your site, but unless a ground barrier is installed it will simply grow back from the neighbouring land. 

The barrier comprises installing a vertical sheet of geomembrane (a special thick plastic) along the affected length of boundary.  Knotweed is so often a boundary problem that over half of BRD’s completed management projects have involved the installation of an in ground barrier.
