The right and wrong way to install a root barrier
This contract involved excavation and removal of Japanese knotweed, Cotoneaster and Horsetail from a large industrial site in Manchester – complete with large scale vertical root barrier installation.
An area of land had already been excavated by another contractor, and it was soon evident that the quality of their root barrier installation was not as it should be.
As you can see from this image above, the area on the left hand side shows the barrier installed by a previous contractor has just been propped up against the boundary with a couple of cable ties, allowing all the off site knotweed to grow over the top and back onto the site. We recommended to the client that this area should be monitored for signs of regrowth.
On the right hand side of the photo is where our team attached a barrier the correct way. The client can be reassured that no knotweed would escape from behind our barrier!

Our team completed the contract by installing the root barrier to the full fence line giving it a flush and tight finish to the boundary therefore stopping any knotweed from growing up behind. This is a proven method of installing a root barrier that has used by our teams on hundreds of contracts.
