Xtract™ - the perfect on site remediation solution for the rapid, reliable and guaranteed eradication of Japanese knotweed from development and construction sites
If you are looking to remove Japanese knotweed from a development site in a matter of days at half the price of "dig and dump" the Xtract™ method, exclusive to Environet, is the solution for you.
It's used by developers (residential, commercial and industrial), local authorities, other government bodies and main contractors who want to benefit from the cost savings, speed and reliability the methods presents.
The cost?
The cost is dependant upon the total volume of infested soil, but typically works out at around 50% of the cost of alternative methods such as dig and dump. We can take the risk on the volume, to give you a fixed lump sum price. No argument!
Reliability?
We designed the Xtract machine for the sole purpose of separating and removing Japanese knotweed rhizome from knotweed infested soils. We have many seasons experience behind us, the method and equipment has been refined, and has patents pending in UK, Europe, America and Canada - we were the first company in the UK, if not in the world, to offer 20 year guarantees to demonstrate our total confidence in the method. No rhizome, no regrowth!
The best environmental option?
Xtract™ is environmentally sound, herbicide free, and involves no haulage or disposal of infested soil to landfill. Reduce waste volumes by approx 98%, avoid needing to import clean replacement fill. A Win Win for you and the environment.
Eradication in days/weeks?
Xtract™ has been developed for sites that need to be cleared in a matter of days, weeks, or months, and yes we can do it. Don't be fooled into thinking you can achieve the same with in-situ herbicide methods. Many have fallen into this trap and then come back to us wanting Xtract™.
Land Remediation tax relief on the costs of treatment?
Xtract™ is an on-site remediation method, that in some circumstances may be eligible for Land Remediation Tax Relief. For more information on claiming tax relief please call us.
Unique ecotechnology developed exclusively by Environet
Xtract™ uses unique patent pending technology developed by Environet. Xtract™ machines are mounted on road trailers, and towed to site by 4x4. Their relatively small size allows them to fit in all but the very smallest development site.
Xtract™ involves the excavation, segregation, and removal of ALL viable Japanese knotweed rhizome in the soil – literally removing the root of the problem. No rhizome, no re-growth!
Infested soils are excavated using a 360° tracked excavator, capable of digging to at least 2m deep. The excavation work is supervised by one of our experts to ensure all soil containing viable rhizome, but not more than is necessary, is excavated.
The excavated infested soils may be pre-screened, the infested soils then are loaded into the Xtract™ machine for separation of the Japanese knotweed rhizome from the soil using vibration technology.
Clean processed soils are then immediately ready for re-use on site. The clean processed soils typically fall into two categories. The fines which are best used as topsoil and the oversize best used as backfill. Please note that these materials must remain on site. If you intend to dispose of them, then waste legislation applies and the material must be consigned as knotweed infested.
The Japanese knotweed rhizome is temporarily stored on site prior to being consigned off site in accordance with Environmental Protection Act 1990 requirements.
Treatment takes a matter of days/weeks depending upon the quantity of material being processed.
The site is left in a clean and safe state ready for development works to commence.
We typically have a one month mobilization period from receipt of written instructions. In urgent situations we may be able to reduce this subject to our other commitments.
