Asbestos products in older real estate are often not recognisable at first glance; in concrete spacers, wall plaster, screed or filler, for example. WESSLING supports you with specialist expert reports and analysis as well as consulting.
Up until the beginning of the nineties, several 100,000 tonnes of asbestos, particularly asbestos sheets, were used in Germany for the construction of real estate both in the private sector, in industrial buildings and in public buildings such as schools. Asbestos can also enter the ground or recycled material unnoticed via construction rubble. The health risks of this substance, which is now banned in Europe, did not become clear until later on. In the light of this, the assessment criteria for asbestos contamination were intensified, so that the need for analysis still remains high. At the same time, existing buildings are being developed more intensively than ever before.
Asbestos remediation: services in detail
As per the new VDI guideline 3876-E, the WESSLING engineers recommend asbestos determination during dismantling and land recycling, the performance of civil engineering works and construction rubble recycling. The reason for this is that, if asbestos contamination is not detected in time, it can lead to cost-intensive delays to your project.
Asbestos enters building rubble during building dismantling, for instance. Asbestos in the soil and in fillings cannot be ruled out even at prior commercial sites and in the area of old landfill sites. The hazardous material has also been found during the use of recycled materials in this way.
Our experts analyse and evaluate your soil as well as your construction and demolition waste. If the findings are positive, we coordinate the following procedure with you, and if desired , with the involvement of the respective authorities. Approvals, usage conditions or remediation recommendations follow depending on the degree of contamination, the composition of the analysed materials and further recycling methods. Our lengthy experience has shown that there are often more cost-effective solutions than dumping.

Asbestos fibres were added to some magnesite screeds and wood concrete screeds into the nineties. Work safety measures therefore have to be taken into consideration in the case of severe damage and during all construction work.
Magnesia and magnesium chloride form a quick-hardening, cement-like mass that can be used as screed in permanently dry areas. Its suitability as an industrial screed with elastic properties is achieved using wood fibres (stone-wood screed).
However, asbestos fibres were also used between the sixties to the nineties. These wood fibre screeds can have very different appearances. Some can be seen to contain fibres with the naked eye, whereas others only reveal isolated, minute wood contents and provide no indication of asbestos. With very little effort, however, they can be checked for asbestos fibres using a scanning electron microscope (SEM).
Like all other floor coverings containing asbestos, little attention is usually paid to polluted floors. As firmly bound asbestos fibre products, they are not subject to mandatory remediation as long as they are not affected by construction measures or extensive destruction. Suitable or even alternative solution options are always available for any plant situation. Ongoing production can also be maintained without the need to increase costs

The use of fillers and wall paints containing asbestos, i.e. fine plaster, in buildings between 1960 and 1990 has often been underestimated. However, the extent of the findings indicates how important this information is. WESSLING develops inexpensive sampling strategies adapted to the project for asbestos and fine plaster, and supports you in measure planning, invitations to tender and execution under consideration of safety and health protection.
The fillers containing asbestos are found in thin layers and are usually concealed by several surface layers. However, they may also be covered by structural plaster and wall paints containing asbestos. Their use within a room changes unsystematically from one partial surface to another.
It should not be forgotten that the fillers were used to fill holes, joints and cracks. The usual search criteria fails here. Prefabricated constructions are currently the central focus of the findings. As knowledge of the situation increases, it is becoming clear that identification in good time is essential in the case of all construction projects.
The economic aspect must also not be underestimated, as the example of a student residence shows: due to the occurrence of asbestos, demolition costs increased from €270,000 to over €750,000 - not including follow-on costs. This aspect also affects many real estate transfers which have been already completed.
At this point, the WESSLING experts advise you in regards to the planning and execution of remediation strategies and ensure that conversion, remediation and dismantling work proceeds smoothly.
WESSLING determines your real estate's asbestos contamination according to the state-of-the-art technology, and analyses the samples quickly, safely and discretely. We therefore ensure your safety in order to prevent internal and public loss of image. Our engineers and life scientists evaluate the need for action through analyses and sampling strategies adapted to the project. Based on this, we offer you remediation measure planning, invitation to tender and specialist site management, giving consideration to safety and health protection. Our experts also deal with the structured sequence of the conversion, remediation and demolition work.
Throughout the entire measure, we always keep sight of the asbestos remediation costs, and aim to ensure that our industrial customers' production and delivery capabilities are not disrupted. WESSLING safeguards your assets and operations as well as the health and safety of your employees.
We will be happy to support you.
