Xtract™

Environet's Eco-Innovative Xtract™ method involves the excavation and screening of soil to separate and remove knotweed rhizome. It can be carried out in a matter of days, involves zero waste to landfill and uses no herbicides.

Resi-Dig-Out™

This method has been developed for residential properties from our patented Xtract™ method, and involves physical excavation and removal of knotweed rhizome from the ground.

DART™

The revolutionary new DART™ method from Environet is the most effective treatment programme available and comes with the added benefit of being less intrusive during the summer when you want to use your garden.


Site Supervision

A cost effective solution for clients who want to provide their own plant, machinery and labour - we supervise.

Bund Method

Stockpile and treat (the Bund method) involves soil excavation and relocation on site, followed by herbicide treatments.

Herbicide Treatments

Herbicide treatment is an effective Japanese knotweed control method, with repeated chemical applications. It's a relatively inexpensive method but it does take at least 2 growing seasons, possibly longer.


Dig and Dump

Knotweed infested soil is excavated under expert supervision and is consigned to landfill in accordance with EPA 1990 requirements.

Root Barriers

A containment method using root barriers to prevent the spread of Japanese knotweed across boundaries.

Stem Injection

A stem injector is used to inject herbicide into the lower part of each mature knotweed stem.
