Japanese Knotweed excavation and disposal off-site.

Sometimes, the only way forward when dealing with Japanese knotweed is to get rid of it by excavation and removal off-site.

You may want to develop a site or simply get your garden back. Whatever the reason, PBA Solutions offers straightforward Japanese knotweed excavation and disposal based on years of experience. Our expertise allows us to make sure that only knotweed impacted material is disposed of, saving you time and money and leaving you ready to move forward with confidence.


Typical Excavation Process:

  1. Implement a site survey and complete a Knotweed Management Plan
  2. Make sure there are no other forms of land contamination and get landfill authorisation
  3. Find a licensed waste carrier and arrange for excavation with suitable machinery
  4. Appoint a Knotweed Clerk of Work and undertake works maintaining site hygiene control
  5. After excavation complete treatment and monitoring including to neighbouring land
  6. Provide and issue insurance backed guarantees

The disposal of Japanese knotweed waste, sometimes called a ‘Dig and Dump’, is a process that can easily trip the unwary. Because all knotweed materials are classed as controlled waste, everyone involved in the process has a duty of care, from the landowner to the specialist, the haulage operator and the chosen landfill site. At PBA we manage the whole process for you with an expert touch, taking away the stress of handling controlled waste and ensuring compliance with legislation.

If machinery and personnel can be provided, one of our qualified Japanese Knotweed Clerk of Works will work alongside the main contractor on a Watching Brief, a system which can reduce costs considerably.
