Technical Standards

Domains of expertise related to: Building materials Data analysis Normes techniques

Many construction materials are likely a medium for mould development. The technical guarantees that these materials may provide resistance to mould growth appears today as a commercial and a major health argument.

Risks and Challenges

Mould growth on building materials may take place in poor conservation condition (on site ...) or after construction if the conditions for use and ventilation are not adequate. Similarly, water damage may be involved in the appearance of mould on the materials.

These developments of mould will not only have a visual impact on the product but also on its physical properties. Moreover, the risks to health are identified because spore and mycotoxins production by these fungi can cause various diseases among building professionals and people living in these contaminated sites (see quality of indoor air).

Our method

Tests for resistance to mould growth are conducted according to a set of international standards that we are able to achieve:

If necessary, we can also apply other standards or protocols.

Each standard is chosen with you after studying the material (plaster, wood, concrete, painting, technical textile, plastic...). It is then carried out in climatic chamber where conditions are controlled. Strains of fungi used are referenced and derived from international culture collections (CBS, IP, ASTM ...) or are isolated from contaminated materials.

Our knowledge of mould also allows us to advise you on the selection of standards but also to adapt them to suit your needs. In collaboration with our Research and Development. We can determine the test conditions and adapt the selection of mold strains following the use of your final product.

Some examples

After moulds spots apparition on a material at an industrial site, we isolated and identified strains of fungi incriminated. Tests subsequently performed to verify the effectiveness of the biocide introduced in the material were carried out with strains previously isolated. This method has therefore the value of working with strains known to cause problems in situ and then validate the effectiveness of the biocide introduced on construction material.
