Japanese Knotweed

Japanese knotweed is an invasive and resilient weed, its foliage forms a dense canopy which restricts growth of ground flora and prevents growth and establishment of native species.   It has gained a fearsome reputation in the construction industry because of its destructive roots - or rhizomes – which can force their way through concrete foundations, buildings, roads, cracking paving and walls. Its penetrating roots can survive extreme temperatures and it can re-emerge and re-grow on its own accord at any time and especially if the contaminated ground is disturbed. 

Impact of Japanese Knotweed


You won’t be surprised to learn that the presence of knotweed can have a detrimental effect on the value of your home.  It can also make it difficult to buy or sell because banks and building societies are often reluctant to offer mortgages on properties with knotweed problems. When Japanese Knotweed is identified on a property, a mortgage provider will often refuse to lend if a management plan is not in place. This is because Japanese Knotweed is an unacceptable risk to lenders.  The same can also apply to Insurance providers.

Totalis Environmental can provide you with a comprehensive Japanese Knotweed Management Plan resulting in the eradication of the plant giving your mortgage company or insurance company the confidence to provide a mortgage or insurance cover.

Japanese Knotweed presents a major problem to construction firms when it is identified in land designated for development.  It can result in bad publicity, poses a significant risk to built structures and hard surfaces, it will discourage financial institutions from providing building insurance, and can impede the sale of such a building.  Usually there isn’t the time to eradicate the plant using herbicide, which requires a 3 – 5 year management plan.  The rhizome can reach 3m deep and stretch 7m in all directions meaning excavating can be time consuming and waste contaminated with Japanese Knotweed is difficult and extremely expensive to dispose of. It only takes a tiny amount to be missed and the Japanese Knotweed can reappear in the future.

Totalis Environmental use innovative techniques and meticulous work practices to reduce the waste produced considerably, therefore significantly minimising the costs and speeding up the process, allowing projects to be delivered on time and within budget.
