Invasive Species Remediation

Eliminate Biological Contamination at the Root

TecZero™ and ETC completely eliminate invasive organisms like Japanese Knotweed from soil — without herbicides, without harming soil structure, and without leaving root fragments behind to regrow.

Why Ex-Situ Treatment Succeeds Where In-Situ Fails

Invasive species like Japanese Knotweed are notoriously difficult to eliminate because even a small fragment of root left behind can regrow. In-situ treatment methods, which act on soil where it sits, can’t guarantee they’ve reached every inch of contaminated ground — pockets and fragments are easy to miss. Iron Creek Group’s ex-situ approach doesn’t have that gap: contaminated soil is fully excavated, so every inch of impacted material passes through treatment, not just the parts a probe or in-ground method happened to reach.

How It Works

Contaminated soil is excavated from the site and treated using TecZero™ or ETC, depending on material condition — TecZero™ for wetter, sludgier ground, ETC for drier soils. The treatment process fully eliminates the invasive organism without damaging the soil’s underlying structure, and the treated soil is then backfilled to its origin. No herbicides, no chemical residue, and no imported replacement fill. Just clean, healthy soil.

Invasive Species Remediation

Effective on Japanese Knotweed and Beyond

Japanese Knotweed is one of the most difficult invasive species to permanently remove, and one of the clearest examples of why ex-situ treatment matters: conventional methods that fail to fully remove its root system simply allow it to return. Iron Creek Group’s technology isn’t limited to Knotweed, though — the same ex-situ process is effective against any invasive biological species. Our technology is mobile and can be operational within days – anywhere in the world.

Frequently Asked Questions

No. The invasive organism is eliminated through thermal treatment, not chemical application.
No. Because the soil is fully excavated and treated ex-situ, the entire root system is addressed — not just the portions a probe or in-ground method happens to reach, which is how regrowth typically occurs with other treatment methods.
No. Treatment eliminates the invasive organism without harming the underlying soil structure, and the treated soil is backfilled on the same site.
No. Japanese Knotweed is a common example, but the same ex-situ process is effective against invasive biological species more broadly.
Yes. Iron Creek Group’s technology mobilizes to project sites anywhere in the world.
No. Treated soil is backfilled on the client’s own site — no need to import replacement fill.
