Hazardous Soil Treatment & Contaminated Land
From discovery to compliant disposal, nationwide
Unexpected contamination is one of the fastest ways to halt a programme. When an excavator uncovers hydrocarbon odours, ash filled made ground, old tanks or discoloured soil, work must stop immediately, and from that moment, contaminated material becomes your legal responsibility.
“A smell of hydrocarbon… Discoloured material that clearly should not be there.”
We manage contaminated and hazardous soil from discovery through classification, testing, treatment and compliant disposal, nationwide.
What we handle
- Hydrocarbon impacted soil: Diesel, petrol, oils and ground around leaking tanks.
- Made ground & historic fill: Ash, clinker, slag, demolition arisings.
- Heavy metals: Lead, arsenic, cadmium, chromium, zinc.
- Asbestos contaminated soil: Fibres, fragments and ACMs under correct controls.
- Chemical contaminants: Solvents, PAHs, phenols, TPH and similar.
- Invasive species arisings: Knotweed affected soil classified as controlled waste.
- Unsuitable but non hazardous soil: Material failing specification for reuse.
Classification determines everything
Correct classification is the biggest cost driver, not removal.
“Material that is genuinely hazardous costs a great deal more to dispose of…
We arrange proper sampling and testing:
- WAC testing to determine landfill class
- Hazardous property coding
- Clear classification before any load leaves site
Treatment options
Hazardous landfill is the simplest route, and usually the most expensive. Depending on contaminant and volume, soil can often be treated to reduce cost or enable reuse:
- Bioremediation
- Stabilisation/solidification
- Soil washing
- Screening and segregation
Compliance done properly
Hazardous waste requires documentation that stands up years later. We ensure:
- Correct EWC coding
- Licensed carriers and permitted facilities
- Consignment notes (hazardous) and waste transfer notes (non hazardous)
- A complete record of where every load went
Keeping your programme moving
Contaminated ground causes disruption mainly when it isn't dealt with quickly.
“The disruption is mostly caused by delay in dealing with it…
Call as soon as contamination is found. We can usually begin sampling immediately, and because we also supply aggregates and run muck away, we can remove contaminated soil, bring in replacement fill and take away ordinary spoil, all through one contact.
Frequently Asked Questions
Stop work, don't move or mix the material, and call us.
Testing determines this, not appearance or smell.
Depends on the test suite; faster turnaround options exist where critical.
Sometimes, depending on contaminant levels and end use.
The waste producer, usually the contractor or site owner, until the material reaches a permitted facility.
Yes, subject to survey and classification.
Yes, nationwide.
