Frequently Asked Questions

How does Japanese knotweed affect construction?

Its aggressive rhizomes can damage concrete, tarmac, and drainage systems, compromising structural stability and increasing costs if untreated.

Can I build on a site with knotweed?

Yes, but only with a compliant management plan. Untreated knotweed can lead to planning denials or project halts.

How long does removal take?

Timelines depend on site conditions and project needs. Excavation offers immediate clearance, while herbicide treatments may span multiple seasons.

What if I need urgent solutions?

We provide emergency excavation and containment to keep your project on schedule while ensuring compliance.
