Anyone removing a floor covering, chipping off tiles, or intending to drill into a façade panel in an older apartment may encounter materials that contain asbestos. This can usually not be reliably determined with the naked eye. Therefore, the decisive factor is not whether something 'typically looks like asbestos', but whether it has been professionally clarified what one is dealing with before drilling, sanding, sawing or breaking.
The current reason for this guide are confirmed asbestos finds in certain Viennese road surfaces. There, the city relies on investigation and sealing, because firmly bound material does not automatically cause the same fiber release as milling or breaking. For the private household, a simple rule can be derived from this:Do not work on undamaged suspicious material and have it checked before renovation work.
If asbestos is suspected, stop first
If a suspicion arises during a renovation, DIE UMWELTBERATUNG recommends stopping work immediately and contacting authorized professionals. Practically, this means:
- do not continue drilling, sanding, sawing, breaking or chiseling;
- do not sweep up dust dry and do not use a regular household vacuum cleaner;
- keep children, pets and uninvolved persons away from the work area;
- leave tools and materials where they are instead of carrying possibly contaminated dust into other rooms;
- photograph the find from a safe distance and note the work location;
- inform the building management, the owner and then a qualified specialist.
A regular dust mask does not make an unknown renovation job a safe DIY project. Even 'careful' breaking or a self-taken material sample can release fibers. The sample should be planned and taken by a competent person.
Where asbestos can be found in older buildings
The Austrian Labour Inspectorate cites widespread use of asbestos fibers especially between 1950 and 1990. This included not only well-known roof and façade panels. Adhesives under tiles or PVC coverings, certain cushion-vinyl floors, ventilation ducts, pipelines, window sills, countertops, sealing cords and insulation can also be affected. With old night storage heaters, it should also be clarified before disassembly which materials were used in the specific model.
Age and appearance only provide a suspicion. A grey component is not automatically asbestos-containing, and an inconspicuous adhesive can still be contaminated. Safety comes from a professional assessment and, if necessary, a laboratory analysis.
| Situation | Recommended next step |
|---|---|
| Material is intact, no work is planned | Do not damage. Collect documents on the year of construction and the component and have them checked before later work. |
| Renovation is planned | Have suspicious components professionally recorded before tendering and the start of work. |
| A suspicion arises during work | Stop work immediately, do not further work on the area and contact professionals. |
| Material is damaged or dust has been released | Clear the area, do not clean anything yourself and clarify further steps immediately with a specialist company. |
How to proceed in seven steps
- Leave the work area unchanged: Do not continue working and do not take parts as display samples.
- Check year of construction and documents: Building plans, invoices, product names, type plates and previous renovation documents can facilitate the assessment.
- Report in writing for rental properties: Inform building management or the landlord before further interventions and document the affected area.
- Commission a professional investigation: Clarify who will carry out the inspection, sampling and laboratory analysis. Do not commission only an anonymous quick test without a traceable sampling plan.
- Determine the remediation approach: Depending on the material and condition, proper leaving in place, encapsulation or removal may be appropriate. This decision belongs in expert hands.
- Check companies: Strict requirements apply in Austria for demolition and asbestos remediation work. The Labour Inspectorate publishes information and a list of authorized companies.
- Clarify disposal in advance: Asbestos-containing material does not belong loose with construction waste or bulky waste. Packaging, labeling, transport and the acceptance point must be determined before the start of work.
A written contract should specify exactly that dismantling and disposal must be carried out in an environmentally and waste-management compliant manner. Also have recorded which areas will be sealed off, how dust will be prevented, who will receive the disposal certificates and when the room can be used again.
When can material remain in the building?
Asbestos is particularly dangerous when fibers can be released and inhaled. Firmly bound, intact materials behave differently than weakly bound or damaged products. Therefore, immediate removal is not automatically the best solution in every situation. Unnecessary breaking can create the exposure you want to avoid. Whether a component can be safely left in place or sealed depends on material type, condition, usage and future work. A professional assessment should document this. It is also important to keep the information discoverable for later owners, tenants or craftsmen so that it is not drilled into unprepared years later.
Please avoid these mistakes
Testing material yourself:
- Cutting or breaking off can generate exactly the dust that should be avoided.Cleaning with a household vacuum cleaner:
- An unsuitable device can release fine particles back into the room air and contaminate other areas.Breaking panels in the skip:
- Asbestos cement should not be thrown or crushed.Painting over a suspected area and forgetting it:
- Even with professional encapsulation, it must remain documented where the material is installed.Deciding only based on the cheapest quote:
- Qualification, work plan, sealing off and disposal certificates are part of the service.If you are planning a new floor anyway, you can find out in advance about
Parquet, laminate and other floor coverings to inform yourself. However, the old construction should only be removed after the pollutant inspection. The same applies to bathroom projects before new tiles are laid are laid. You can find general information on the disposal of large household items in the article on bulky waste collection; however, asbestos-containing material requires its own, proper disposal route.
Frequently Asked Questions
Can I recognize asbestos by color or texture?
No, not reliably. Year of construction, product type and installation location can give cause for suspicion. Whether asbestos is actually present is clarified by a professional investigation or analysis.
May I continue working next to an intact panel?
That depends on whether the planned work could shake, drill into or otherwise damage the suspected material. Before starting, the interface should be professionally assessed and the work area clearly defined.
What do I do after an accidental damage?
Stop work, leave the area, keep other people away and do not sweep or vacuum yourself. Inform building management or the owner and a qualified specialist company. In case of concrete health concerns, medical advice may also be advisable.
