Contaminated ground removal
- Commercial
Former industrial land and fuel sites often carry contamination left behind by previous uses. Heavy metals and fuel in the ground must be removed before construction can proceed.
We remove contaminated ground as part of the groundworks package, so it is managed by the same team that builds the foundations.
Key
- Contaminated material (heavy metals, fuel)
- Extent of excavation, removed and replaced with clean fill

Contaminated ground excavation
Scale
NTS
Typical section: contaminated ground removal. Indicative, not to scale.
The challenge
Contamination is the unknown that stops a site
Until the extent is known, nobody can give an honest price, and a find halfway through excavation can halt the programme.
We have delivered specialist groundworks across the North West since 2008. We know where these projects go wrong, and we plan for it before work starts.
What we deliver
Contaminated ground removal, done properly
Heavy metals
Ground carrying heavy metals from previous industrial use, excavated and removed so the site can be developed.
Fuel
Ground contaminated by fuel, for example around former tanks and forecourts, excavated and removed.
Our process
Site to sign-off
Three steps, whether it is a machine base for a factory or a treatment plant for a farmhouse.
Step 1: Tell us about the project
Call us or send the drawings. If it helps, we will arrange a site visit.
Step 2: A clear price, with the risks identified
We review the ground conditions, access and programme, and raise anything that could add cost later, while it is still inexpensive to resolve.
Step 3: Delivered and signed off
Built to programme by our own team and plant, and handed over with the paperwork that goes with it.
What is at stake
When groundworks goes wrong
- Work stopped while a find is investigated
- Costs that escalate without a clear scope
- Contaminated material handled incorrectly
When it is done right
Contamination removed within a clear scope, by the same team that then builds on the site.
What affects the price
Every project is priced on its own requirements. These are the factors that make the biggest difference, and we will discuss each one with you before work starts.
- The type and extent of contamination
- How the material is classified for disposal
- Volume to be removed and replacement fill
- Water in the excavation
Accreditations for this work
Our health and safety management has already been independently assessed, which shortens your pre-qualification.
If your organisation manages its supply chain through Avetta, we are already registered.
- Confined Spaces
Connections and chamber work proceed without waiting for a specialist subcontractor.
Questions we get asked
Can you give a fixed price before the ground is tested?
Not responsibly. Until the type and extent of contamination are known, any fixed figure is an estimate. Call us to discuss what is already known about the site.
Have a project that needs pricing?
Send us the drawings, or we will arrange a site visit. We will give you a clear price and tell you about any risks we can see.
