KNOTWEED Excavation services across Wales

Excavation is the only way to get rid of Japanese knotweed once and for all. Our fully qualified skilled operatives will clear your land of knotweed, with complete removal and disposal of all contamination.

Japanese knotweed is a highly resilient invasive species of weed that is capable of growing new shoots from its root network. These special roots are known as rhizomes, and even a tiny piece as small as 0.5g is capable of allowing the infestation to regrow. With root systems that bury deep into the ground, excavation of the contaminated soil is the best way to completely remove the infestation.

Taking control of Japanese Knotweed in wales

One of the best option for homeowners or landowners who would prefer not to have excavation carried out is Chemical Treatment (herbicide). Herbicides applied under a planned treatment programme will control its growth and stop the spread. Over time it exhaust the plant’s ability to grow and will force it into a dormant state.

The treatment programme will prevent the plant producing aerial growth and additionally, prevent the rhizomes from growing further. If the knotweed area is likely to be disturbed physical removal of the knotweed may be required instead.

Treatment methods include stem injection, herbicide spray and leaf wiping. Our herbicide programmes are packaged within a  Knotweed Management Plan (KMP), which comes with an Insurance Backed Guarantee.

what does it cost to get rid of KNOTWEED in wales 

The average cost to remove Japanese knotweed in Wales varies, depending on the methods involved and the size of the affected areas. If it is identified and dealt with promptly, the costs of removing Japanese knotweed can be kept to a minimum. Long-term herbicide treatment is usually the most cost-effective control method. Our professionally delivered herbicide treatment programme will provide successful chemical control of Japanese knotweed within a period of 3-7 years.

Excavation of Japanese knotweed costs more than herbicide treatment due to labour, materials, waste removal and reinstatement costs. However, it ensures complete Japanese knotweed removal allowing free use or development of the property. We provide cost-efficient excavation due to our extensive experience whilst minimising waste volumes.

Following our professional surveys we will provide you with a no-nonsense, comprehensive report with no-obligation recommendations and quotes.

can you DIY?

There are lots of theories on the internet about how to remove Japanese knotweed – from using a lawnmower to using a flamethrower. The truth is that there is no way to deal with Japanese knotweed yourself. You need to have a plan in place to control the Japanese knotweed, or you need to excavate it to get rid of it once-and-for-all.

As knotweed is an invasive species that is classed as “Controlled Waste” it can only be removed by licensed organisations. It must be disposed of safely at a licensed landfill site by a registered waste carrier. Carelessly disposed of, knotweed can cause an infestation. Due to this, and the legal issues surrounding knotweed, we do not advise you try to undertake this operation yourself. Contact us instead.
