Asbestos in Soil Assessment & Remediation
Asbestos contamination in soil is a serious environmental and health hazard that can arise from fly-tipping, demolition debris, or the historical burial of asbestos waste on brownfield and residential land. If asbestos fibres are disturbed — by gardening, construction works, or children playing — they can become airborne and pose a significant inhalation risk. Pro Asbestos Removal provides comprehensive asbestos in soil assessment, sampling, risk assessment, and licensed remediation services across Surrey, London, and the South East.
The Risk You Can't See
Asbestos in soil is frequently invisible to the naked eye. Fragments of asbestos cement, pipe lagging, and insulation board can lie buried across a site, only becoming dangerous when disturbed by groundworks, landscaping, or children playing. Many landowners discover contamination only when a Phase 2 environmental survey is commissioned ahead of a sale or development.
How Asbestos Contamination Spreads in Soil
Asbestos fibres in soil become hazardous when disturbed and made airborne. Chrysotile, amosite, and crocidolite can all persist in soil for decades without degrading. Under the Environmental Protection Act 1990 and the Contaminated Land (England) Regulations 2006, land contaminated with asbestos is classified as a statutory nuisance, and landowners have a legal duty to remediate once contamination is identified. The Environment Agency requires a detailed remediation strategy before any licensed removal can begin.
The Environment Agency estimates that over 300,000 hectares of land in England and Wales are affected by some form of contamination, with asbestos among the most commonly identified hazardous materials on brownfield sites (Environment Agency, 2022).

How We Work
Initial Assessment & Sampling
A qualified surveyor visits the site to assess the extent of contamination and collect soil samples for analysis by a UKAS-accredited laboratory. Samples are taken in accordance with BS EN ISO 15202 and the Environment Agency's guidance on asbestos in soil.
Risk Assessment Report
Laboratory results are used to produce a detailed risk assessment report that quantifies the level of contamination, assesses the risk to human health and the environment, and recommends a remediation strategy.
Remediation Works
Licensed operatives excavate and remove asbestos-contaminated soil using appropriate PPE and controls. All contaminated material is double-bagged, labelled, and transported to a licensed disposal facility.
Validation Sampling
On completion of remediation works, validation soil samples are taken to confirm that the site has been successfully remediated to the agreed target levels.
Documentation & Reporting
A full remediation report is produced, including laboratory results, disposal documentation, and validation sampling data. This report is suitable for submission to planning authorities and for land registry purposes.
When You Need to Act
Asbestos debris is visible on the surface of the land
Act NowVisible asbestos is an immediate inhalation risk and a statutory nuisance under the Environmental Protection Act 1990.
Groundworks or landscaping planned on a brownfield or former industrial site
This WeekDisturbing asbestos-contaminated soil without a prior risk assessment breaches HSE and Environment Agency guidance.
Phase 1 environmental report has flagged potential asbestos contamination
This MonthA Phase 2 intrusive investigation is required before any planning permission can be granted or sale completed.
Purchasing land with a history of industrial or demolition use
Plan AheadBuying contaminated land without due diligence transfers full remediation liability to the new owner.
The Most Expensive Mistake We See
Landowners frequently attempt to bury or cover asbestos-contaminated soil rather than remediate it — this does not discharge the legal duty and can result in enforcement action from the Environment Agency.
Our Approach to Asbestos in Soil Remediation
Our approach to asbestos in soil combines environmental science with practical site management. We work with environmental consultants, planning authorities, and the Environment Agency to produce remediation strategies that are technically sound, legally defensible, and delivered on time.
Common Questions
How does asbestos get into soil?
Asbestos can enter soil through fly-tipping of asbestos waste, the demolition of buildings containing ACMs where debris was not properly removed, the historical practice of burying asbestos waste on site, and the weathering and fragmentation of asbestos cement materials left on the ground surface.
Is asbestos in soil dangerous?
Asbestos in soil is most dangerous when it is disturbed and fibres become airborne. Activities such as digging, gardening, and construction works can disturb asbestos-contaminated soil and create an inhalation risk. Intact asbestos buried deep in the ground poses a lower immediate risk, but should still be assessed and managed.
Do I need to disclose asbestos in soil when selling land or property?
Yes. Landowners have a legal duty to disclose known contamination when selling land or property. Failure to disclose known asbestos contamination can result in legal liability. An asbestos in soil assessment report provides the evidence needed to demonstrate due diligence.
What is the Environment Agency's guidance on asbestos in soil?
The Environment Agency's guidance on asbestos in soil is set out in the CLR11 framework and the specific guidance document 'Asbestos in Soil and Made Ground'. This guidance provides a tiered risk assessment approach for evaluating the risk to human health from asbestos in soil.
Do you cover Surrey and the South East for asbestos in soil assessment?
Yes. We cover Surrey, London, Kent, Sussex, Essex, Berkshire, and Hampshire for asbestos in soil assessment and remediation works.
