If you have a house that was built before 1994 or if you are planning to buy one, then there is the possibility that asbestos-containing materials have been used during construction. An inventory of asbestos type A gives you an insight into the presence of directly perceptible asbestos-containing materials. This inventory is carried out by a certified inspector using slightly destructive testing (if necessary). After the inspection you will receive a certified (SC-540) report.

In cooperation with Contraa asbestos expertise and advice, ADA Keur offers a certified inventory of asbestos type A. Our inspectors have many years of experience and use state-of-the-art tools in order to carry out an optimally complete inventory. This prevents unnecessary exclusions. The accuracy of the inventory is guaranteed by thorough preparation, planning and organisation.
The inventory of asbestos

If you suspect that asbestos has been used in your house or the house that you want to buy, you can rule out this possibility through an inventory of asbestos type A. Prior to inspection the execution of the inventory is discussed with you as client. You will deliver construction plans and specifications to us if available. If this information is not available, the archives are consulted for available information. The follow-up of the investigation will be based on the construction plans and historic information.

During this inspection, which is certified in accordance with the SC-540 norm, the house is inspected and all asbestos-suspicious applications are recorded. Samples are taken with state-of-the-art techniques to determine of asbestos fibres may be released. The inspector carrying out the inspection on site has a personal certificate Expert Inventory Taker Asbestos and a diploma Safety for Operational Supervision VCA (VOL-VCA). In addition, he has signed a behavioural code and declaration of secrecy to ensure correct execution and confidential treatment of your data.


After completion of the inventory on site, all data and the analysis certificates are combined in a clear report. The report contains clear drawings, photos and an (first) advice about how to handle the asbestos-containing applications that were found.

What is asbestos?

Asbestos is a collective name for a product that used to be used a lot thanks to its many applications. Asbestos is strong, wear-free, and-resistant to heat, lyes and acids. It insulates well and was quite cheap. After it was found out that asbestos has negative properties as well, it has been forbidden to sell asbestos since 1 July 1993, as asbestos consists of microscopically small, needle-like fibres that can cause lung cancer, pneumocomiosis (asbestose) or lung and peritoneum cancer (mesotheliome) when inhaled.

Friable and non-friable asbestos

Asbestos was used in two variants. The friable variant is, for instance, asbestos cement board. These boards are used for roofing and façades, among others, but also for lining venting channels and flue pipes. Non-friable asbestos includes air-placed asbestos. This product is mainly used for insulation, but also as fire protection on, among others, H profiles in commercial properties and hospitals.

The samples taken during the inventory are assessed using polarisation microscopy for the presence of non-friable asbestos. In the case of friable asbestos, there is little risk of fibres being released into the air, as long as the asbestos has been mounted properly and not damaged. Of course friable asbestos should never be sawn or drilled, nor may the product be processed in any other way (including sanding).
