Asbestos in Industrial Units & Warehouses
Industrial units, warehouses, factories, and distribution centres built before 2000 contain some of the most hazardous asbestos environments in the UK built estate. Corrugated asbestos cement roofing, sprayed coatings on structural steelwork, and heavy pipe lagging systems were standard construction materials throughout the post-war industrial building boom. Pro Asbestos Removal provides fully licensed asbestos surveys, management plans, and removal services for industrial buildings across Surrey, London, and the South East — working directly with building owners, facilities managers, principal contractors, and demolition companies to deliver safe, compliant, and programme-integrated asbestos removal.
The Risk You Can't See
Industrial buildings constructed between the 1950s and 1990s represent some of the highest-risk asbestos environments in the UK. Corrugated asbestos cement (AC) roofing was the default material for factories, warehouses, and distribution centres throughout this period — cheap, durable, and fire-resistant. Sprayed asbestos coatings were applied to structural steelwork as fire protection. Pipe lagging insulated heating and process pipework throughout the building. The result is that a typical industrial unit of this era may contain three or four distinct ACM types, each requiring a different removal method, a different level of licensing, and a different disposal route. Cutting corrugated AC sheets without wet suppression generates mean airborne fibre concentrations of 24.0 f/cm³ — 240 times the UK control limit of 0.1 f/cm³. Dry removal of sprayed asbestos generates average concentrations of 16.4 f/cm³. These are not theoretical risks: they are measured, published figures from peer-reviewed research. Industrial building owners and facilities managers who commission refurbishment or demolition works without a prior refurbishment and demolition survey, or who allow contractors to work without a licensed asbestos contractor present, are exposing workers to concentrations that carry a measurable lifetime cancer risk.
The Specific Asbestos Risks in Industrial Buildings
Industrial buildings present a different risk profile from domestic or commercial office environments. The ACMs most commonly found — corrugated AC roofing, sprayed coatings on steelwork, and heavy pipe lagging — are all high-fibre-release materials when disturbed without proper controls. Corrugated asbestos cement roofing was used extensively on UK factories and warehouses from the 1950s through to the mid-1980s. It typically contains 10–15% chrysotile by weight. Cutting, drilling, or breaking these sheets without wet suppression and respiratory protective equipment generates fibre concentrations far above the UK workplace exposure limit. Gottesfeld (2023) reviewed published and unpublished air sampling data and found that cutting flat boards and corrugated AC sheets produced exposures ranging from 1.3 to 130.0 f/cm³, with a mean of 24.0 f/cm³ — and that more than 86% of tasks involving AC sheet exceeded the US short-term excursion limit. Sprayed asbestos coatings on structural steelwork are a different challenge. Applied as fire protection in industrial buildings from the 1950s to the early 1970s, they typically contain amosite or crocidolite — the most potent asbestos fibre types. Paik et al. (1983) found that dry removal of sprayed asbestos generated average fibre concentrations of 16.4 f/cm³ at workers' breathing zones. Wet methods reduced this to under 2 f/cm³, which is why licensed removal with full enclosure and wet suppression is legally required for this material type. The consequences of uncontrolled removal are severe. Dumortier et al. (2012) reported a case where two workers carried out uncontrolled amosite removal from a former industrial hall for approximately one week without regulatory protective equipment. Mineralogical analysis of bronchoalveolar lavage fluid 18–22 months later revealed fibre retention consistent with airborne concentrations of 'several tens to about a hundred' f/mL — comparable to historical occupational exposures from the peak asbestos era.
Cutting corrugated asbestos cement sheets generates mean airborne fibre concentrations of 24.0 f/cm³ — 240 times the UK control limit of 0.1 f/cm³. More than 86% of tasks involving AC sheet cutting exceed the US short-term excursion limit.

How We Work
Refurbishment & Demolition Survey
Before any demolition or intrusive refurbishment, a P402-certificated surveyor carries out a full refurbishment and demolition survey of the affected areas. This intrusive survey accesses voids, lifts floor coverings, and opens up building fabric to identify all ACMs in the areas of planned works. The survey report identifies every ACM by type, location, extent, and condition, and forms the basis of the plan of work for licensed removal.
Plan of Work & HSE Notification
For all licensed asbestos work, a written plan of work is prepared and submitted to the HSE at least 14 days before work begins. The plan of work sets out the ACM types, quantities, removal methods, enclosure design, air monitoring arrangements, decontamination procedures, and waste disposal route. The plan is shared with the principal contractor and incorporated into the construction phase plan under CDM 2015.
Site Setup & Enclosure
Licensed operatives establish full enclosures around the work area, with negative pressure units (NPUs) maintaining a negative pressure differential to prevent fibre migration. Decontamination units (DCUs) are installed at the enclosure exit for full three-stage decontamination of operatives and equipment. All adjacent areas are isolated and access is restricted to licensed personnel.
ACM Removal
All ACMs are removed using wet suppression to suppress fibre release, Type H HEPA-filtered vacuum cleaners for dust control, and hand tools wherever possible to minimise fibre generation. Corrugated AC roofing sheets are carefully dismantled and lowered — not dropped — to prevent breakage. Sprayed coatings are removed using wet methods with full enclosure. All removed material is double-bagged in UN-approved asbestos waste sacks and labelled for licensed disposal.
Clearance Air Testing & Handover
On completion of all licensed works, an independent UKAS-accredited analyst carries out the four-stage clearance procedure: visual inspection, thorough visual inspection, background air sampling, and clearance air sampling to the 0.01 f/cm³ criterion. A clearance certificate, waste consignment notes, and updated asbestos register are provided to the duty holder and principal contractor for their compliance records.
When You Need to Act
Corrugated asbestos cement roofing is damaged, leaking, or scheduled for replacement
Act NowDamaged or weathered AC roofing releases fibres continuously into the environment. Replacement or repair must be carried out by a licensed contractor using wet suppression, full PPE, and licensed waste disposal. Attempting to repair or replace AC roofing without a licensed contractor is a criminal offence under CAR 2012 where the material is in a friable or damaged condition.
Industrial building demolition or major refurbishment is being planned
This WeekA refurbishment and demolition (R&D) survey is legally required before any demolition or intrusive refurbishment begins. Under CDM 2015, the principal designer must ensure the R&D survey is commissioned and its results communicated to all parties before work starts. Demolition without a prior R&D survey exposes the principal contractor and building owner to HSE enforcement, unlimited fines, and potential manslaughter charges if a worker is harmed.
The building has no asbestos register or the register has not been reviewed since acquisition
This MonthCAR 2012 Regulation 4 requires all non-domestic premises to have a written asbestos management plan. An industrial building without a current register leaves every maintenance contractor working in the building uninformed of ACM locations, creating a foreseeable risk of exposure and direct liability for the duty holder.
Maintenance workers are carrying out routine tasks — drilling, cutting, or disturbing building fabric
Plan AheadRoutine maintenance activities in industrial buildings — fixing roof leaks, installing cable trays, replacing pipe insulation — are among the most common causes of uncontrolled asbestos exposure in the UK. Every maintenance worker who may disturb asbestos must hold asbestos awareness training under CAR 2012 Regulation 10, and must consult the asbestos register before starting any task that involves disturbing building fabric.
The Most Expensive Mistake We See
The most common failure in industrial asbestos management is commissioning a management survey and treating it as sufficient for demolition or major refurbishment works. A management survey is a non-intrusive inspection designed for ongoing occupation — it does not access voids, lift floor coverings, or open up building fabric. A refurbishment and demolition survey is legally required before any intrusive works begin, and it must cover the specific areas affected by the planned works. Building owners and principal contractors who proceed with demolition on the basis of a management survey alone are in breach of CAR 2012 and CDM 2015.
Our Approach to Industrial Asbestos Removal
Industrial projects require a different level of planning and resource than domestic or commercial office removals. Large-volume corrugated roofing, sprayed coatings on structural steelwork, and extensive pipe lagging systems all require method statements tailored to the specific building, the specific ACM type, and the specific programme of works. Our project managers work directly with principal contractors, demolition companies, and building owners to produce method statements, plans of work, and waste management schedules that integrate with the overall construction programme. Every industrial removal is carried out by HSE-licensed operatives with full enclosures, negative pressure units, and independent UKAS-accredited clearance air testing on completion.
Common Questions
Does all asbestos in an industrial building require a licensed contractor?
Not all ACMs in industrial buildings require a licensed contractor, but the most common and hazardous types do. Corrugated asbestos cement roofing in good condition may qualify as non-licensed work if it can be removed without breaking or cutting — though in practice, large-scale roof removal almost always requires a licensed contractor. Sprayed asbestos coatings on structural steelwork are always licensed work. Asbestos insulation board (AIB) is always licensed work. Pipe lagging is always licensed work. The safest approach for any industrial building is to commission a refurbishment and demolition survey before any works begin, which will identify the ACM types present and confirm the required licensing category for each.
What is the difference between a management survey and a refurbishment and demolition survey for an industrial building?
A management survey is a non-intrusive inspection designed to identify ACMs that could be disturbed during normal occupation and routine maintenance. It is the baseline survey required for CAR 2012 Regulation 4 compliance. A refurbishment and demolition survey is a more intrusive inspection required before any demolition or intrusive refurbishment begins. It involves accessing voids, lifting floor coverings, and opening up building fabric to identify all ACMs in the areas of planned works. For industrial buildings undergoing demolition or major refurbishment, only a refurbishment and demolition survey is sufficient — a management survey does not meet the legal requirement.
How long does industrial asbestos removal take?
The duration of industrial asbestos removal depends on the type, quantity, and location of ACMs. A single corrugated AC roof on a small industrial unit may take 2–3 days. A large warehouse roof with sprayed coatings on steelwork and extensive pipe lagging may take several weeks. The 14-day HSE notification period must be factored into any programme of works. We will provide a detailed programme as part of the plan of work, and we work with principal contractors to integrate removal works into the overall construction programme.
Can industrial asbestos removal be carried out while the building is occupied?
Licensed asbestos removal in occupied industrial buildings is possible where a full enclosure can be established to isolate the work area from occupied spaces, and where independent air monitoring confirms that fibre concentrations in occupied areas remain below the control limit. In practice, large-scale roof removal or sprayed coating removal in an occupied building is very difficult to manage safely, and we strongly recommend scheduling these works during a planned shutdown or out-of-hours period. We will advise on the safest and most practical approach for each project.
What happens to the asbestos waste from an industrial removal project?
All asbestos waste from licensed removal works is classified as hazardous waste under the Hazardous Waste Regulations 2005. It must be double-bagged in UN-approved asbestos waste sacks, labelled with the correct hazardous waste markings, and transported by a licensed waste carrier to a licensed hazardous waste disposal facility. A Hazardous Waste Consignment Note must be completed for every load. We handle all waste documentation and provide copies to the duty holder for their compliance records. Asbestos waste cannot be disposed of at a standard skip or general waste facility.
Do we need an asbestos survey before buying an industrial property?
There is no statutory requirement for a pre-acquisition asbestos survey, but it is strongly recommended for any industrial property built before 2000. Industrial buildings of this era almost always contain ACMs — often in large quantities. A pre-acquisition survey identifies the presence, type, condition, and extent of ACMs before contracts are exchanged, allowing the buyer to quantify the cost of removal, negotiate the purchase price, and plan for any required works before taking occupation. Without a pre-acquisition survey, the buyer inherits the full duty to manage asbestos from completion — including any liability for ACMs that were present but undisclosed at the time of purchase.
