Certified testing for asbestos, mold, and pyrite

Asbestos is a fibrous mineral substance that has been used in numerous construction materials and manufactured products due to its fire resistance, heat resistance, and chemical resistance. However, exposure to asbestos has been shown to cause serious health problems, including lung cancer and mesothelioma.

As a result, asbestos has been banned in many countries, including Canada, where its use was gradually phased out starting in the 1970s. Nevertheless, many buildings constructed before this period may still contain asbestos, particularly in insulation, roofing materials, flooring, and pipes.

This is why Géosphère Consultants provides asbestos air and bulk analyses services in buildings to ensure its absence before renovation and/or demolition work. Additionally, with its professional team, Géosphère Consultants is capable of asbestos decontamination according to CNESST standards, supported by a professional and scientific report.


Mold is a common issue in buildings, especially in damp or poorly ventilated areas. It can develop on both interior and exterior surfaces of buildings, including walls, ceilings, floors, carpets, furniture, and personal items. Mold thrives in the presence of moisture, heat, and organic materials, such as cellulose found in building materials like drywall, wood, particleboard, and carpets.

Mold can cause health problems, including allergies, eye, nose, and throat irritations, headaches, rashes, and respiratory issues. Those most sensitive to mold include children, the elderly, individuals with allergies or asthma, and those with weakened immune systems.

It is, therefore, important to conduct mold tests to assess indoor air quality. Géosphère Consultants, with its indoor environment department, can conduct necessary air tests following standards established by the Institut national de santé publique du Québec (INSPQ).


Pyrite is a common mineral composed of iron sulfide (FeS2). When exposed to air and water, pyrite can chemically react to form sulfuric acid, which can dissolve metals and other materials in the soil. This chemical reaction can also lead to the formation of caves and cavities in rocks, which can damage the foundations of buildings constructed on these soils.

In the construction context, the presence of pyrite in soils can pose stability and foundation problems for buildings. Building owners and engineers must, therefore, be aware of the presence of pyrite in soils and take measures to prevent or address potential issues. This is why it is essential to conduct tests to determine the presence or absence of pyrite beneath the concrete slab.
