Japanese knotweed can be a very destructive species. The horticulturists who introduced it into Britain’s gardens in the 19th century valued its aesthetics and Fallopia Japonica was actually highly prized as an ornamental border shrub. Of course, they knew nothing about the plants tendency to destroy building foundations, or its resilience to domestic herbicides.
Since its introduction, knotweed has caused continued grief and expense to landowners, because the species is hardy enough to resist domestic herbicides, attempting to eradicate a knotweed infestation yourself is not advisable. When exposed to domestic herbicides the plant actually develops a resistance that can then mean you have to pay a specialist for many more treatments than would otherwise have been required.
Knotweed removal specialists have developed an array of effective treatments that can be used to successfully control the species and eradicate it for good, thereby giving land owners the peace of mind which comes from knowing their buildings and other structures are safe from the plants destructive rhizome root system which can occupy a huge cubic area and damage anything it comes into contact with.
Because knotweed destroys building foundation and drainage works, many land owners have had to foot expensive repairs bills due to either failing to identify the Japanese knotweed removal, or failing to take action regarding its eradication. The best way of dealing with knotweed, and the only way to ensure that expensive repair bills are avoided is to effectively eradicate the infestation as soon as the problem is identified. By utilizing a specialist contractor, you leave no chance of regrowth or of the infestation encroaching on to neighbouring properties.
Left unresolved, the potential for damage is horrific, not only concerning the repair of your own property, but should the infestation spread to neighbouring properties, you may find yourself being sued for unreasonable interference under common law.
Because knotweed is classified as controlled waste under the 1990 environmental protection act, you cannot simply dig up the knotweed and put it in your wheelie bin. There are two options for the disposal of this controlled waste which are widely used by specialist contractors, the first and probably the most cost effective is cell burial. In this method, the contaminated materials are encapsulated inside a special membrane, which is then sealed shut and buried on-site to a minimum depth of two metres. The second option is to dispose of the waste at a specialist land fill site, this option is usually only used where on site burial is not an option since it is very expensive.
