Asbestos In Soils Testing Across the UK
Asbestos in soils cannot be reliably identified by the naked eye. It requires laboratory analysis in a UKAS accredited facility to determine whether asbestos is present, in what form and at what concentration.
The Testing Lab PLC (TTL) is UKAS ISO/IEC 17025:2017 accredited for asbestos in soils testing, providing identification and quantification of asbestos fibres in bulk samples of soil, aggregates and sediments, carried out in our purpose-built laboratory.
We support consultants, contractors and developers across the UK with robust data for risk assessment, management and waste classification on brownfield and contaminated land projects.

UKAS accredited asbestos in soils testing
Our accredited scope covers qualitative and quantitative analysis of asbestos in soils and construction & demolition (C&D) materials, in line with:
-
HSE guidance HSG248 – Asbestos: The Analysts’ Guide (2nd edition, including soils and made ground)
-
The SCA “Blue Book” method for identifying and quantifying asbestos in soils and associated materials
-
CAR-SOIL™ – the industry guidance interpreting the Control of Asbestos Regulations 2012 (CAR 2012) for asbestos-contaminated soil and C&D materials
TTL routinely participates in the Asbestos in Soils Scheme (AISS) proficiency testing programme run by HSE’s laboratory, which assesses the performance of laboratories undertaking qualitative and quantitative asbestos in soils analysis.
What is asbestos in soils?
“Asbestos in soils” refers to asbestos-containing materials (ACMs) and asbestos fibres present within soil, made ground or C&D materials. This can occur as:
-
Visible ACM fragments (e.g. cement, AIB, textured coatings)
-
Smaller debris mixed into made ground
-
Dispersed fibres within the soil matrix
Research has shown asbestos can be present in a significant proportion of made ground samples on brownfield sites.
Asbestos in soil presents a risk when fibres can be released into the air and inhaled, for example through excavation, earthworks, stockpiling, trafficking or wind erosion.

How asbestos gets into soil and made ground
Soil and made ground can become contaminated with asbestos in many different ways, including (but not limited to):
-
Historic demolition of buildings containing asbestos, with fragments left in made ground or backfill
-
Fly-tipping or illegal disposal of asbestos-containing materials
-
Redevelopment of brownfield sites with past industrial or commercial uses involving ACMs
-
Historic use of asbestos-contaminated fill, hardcore or demolition arisings
Due to the nature of asbestos fibres, once previously undisturbed ground is disturbed, the potential for fibre release and exposure increases, creating risks for workers, neighbours and the environment.
CAR-SOIL™ (Control of Asbestos Regulations 2012: Interpretation for Managing and Working with Asbestos in Soil and C&D Materials) requires employers to undertake appropriate risk assessment and control where there is a potential for exposure to asbestos in soils and C&D materials.
Our asbestos in soils testing methodology
TTL’s asbestos in soils analysis typically comprises three core stages:
Using asbestos in soils data for risk assessment and waste classification
Our asbestos in soils results can be used to support:
Our technical team can work with your geo-environmental and H&S advisers to interpret the results in the context of CAR 2012, CAR-SOIL and project-specific risk assessments.

Frequently asked questions about asbestos in soils
Our Accredited Testing Services
Thank you very much for the air sampling results – and please accept our grateful thanks for resolving this issue so quickly and for the promptness of the report.
Your analyst, Lee, was very helpful and his suggestions and advice appreciated.
We would have no hesitation in recommending The Testing Lab and will be in touch soon with regards arrangements for a full asbestos survey for the rest of the site.
TTL have been working directly as my analyst for the last 12 months on a very complex asbestos removal scheme, they have achieved all of their KPI’s without fail and on a number of occasions surpassed their SLA in acting for us on planning issues associated with the demolition in regard to contamination which cannot be removed as part of the normal sequence of operation.
There reports are always issued within timescales and they have policed the reports by the Licensed asbestos contractor faultlessly sometimes in very difficult circumstances.
