Building characterization

Characterization of asbestos

Identification of materials likely to contain asbestos

Our experts support you throughout the identification process.

  • Analysis of the sampling strategy to be implemented according to the history of the building and the materials in place.
  • Inspection of buildings to locate materials likely to contain asbestos (MLCA).
  • Sampling and analyzing materials according to CNESST guidelines for the number of samples required.
  • Determining whether there is asbestos in materials, setting up or updating the asbestos management register, and drafting asbestos removal specifications.

Update of the asbestos registry

Document the presence of asbestos in the building

Our experienced team can create mandatory registry of materials likely to contain asbestos (MLCA) and perform the necessary updates every two years, especially for thermal insulation and flocking, or any other material containing asbestos (MCA).

  • Establishment of a registry when it is non-existent or incomplete
  • Updating an existing complete register
  • MCA conditions inspection
  • Identification of issues
  • Recommendations if the materials are deteriorated

Asbestos management plan

Plan your work in the presence of asbestos according to the risks


In the presence of asbestos in a building, our experts support our clients in establishing a preventive management plan. This plan makes it possible to plan all activities that may create asbestos dust whether during maintenance or renovation work. By supporting our client throughout the process, we can offer the best solutions to ensure the health of everyone, from planning to asbestos removal.

Management of asbestos removal work

Before, during, and after asbestos removal work

Whether it is for a site supervision where we produced an asbestos removal estimate or according to an existing estimate, our professionals manage the asbestos removal site.

  • Verification of the conformity of the area to be removed
  • Site supervision and daily air check
  • Certification of the efficiency of the asbestos removal work during the final air test
  • Analysis of samples by our counters recognized by the IRSST

Hazardous materials identification

Hazardous materials identification

Preventing risks by identifying hazardous materials in buildings

To ensure the safety of workers carrying out work in a building that generates dust, it is essential to identify the hazardous materials that may be present (lead, mercury, beryllium, PCBs).

Our experts can carry out the identification of hazardous materials, their sampling and their analysis, but also the drafting of decontamination protocols, management and monitoring of decontamination sites. We can also carry out post-work tests to confirm the quality of the decontamination work.

Building audits

Have a clear view of the state of your assets


Whether it is for the purchase, renovation, or demolition of a building, our experts can assist you in the assessment of materials of concern that may be found there. Once the identification is complete, we will accompany you through all stages of the decontamination process if applicable.

Safe management

Adopt good practices now


To comply with the various rules related to the management of hazardous and residual materials, our team of experts can assist you in the implementation of various action plans. They consider the most recent standards, while having a great concern to protect our environment.

In the event of a spill, our 24/7 emergency service responds quickly to set up an effective decontamination protocol.

Asbestos fibres in the air

Asbestos fibres in the air

Before, during and after asbestos removal work


Our counters recognized by the IRSST are able to analyze total fibres in the air in a quick and efficient manner. When the situation demands it, we can specifically identify asbestos fibres in samples.

Our experience and our rigour allow us to support and advise you throughout the asbestos removal process.

Whether for daily, final or preventive tests, you will receive the results as soon as possible.

Asbestos in materials

Determine the concentration of asbestos in your materials


As a material is likely to contain asbestos until proven otherwise, our team is able to support you in this analysis process, until decontamination.

For all types of materials (heat insulation, flocking, plaster, vinyl tiles, joint compounds, vermiculite, etc.), analyses are carried out in our certified laboratory, using recognized methods.

  • ELAP 198-1 Method — Characterization of asbestos fibres in non-friable materials by transmission electron microscopy (TEM)
  • IRSST-244 Method — Characterization of fibres in dust or bulk materials

Vermiculite containing asbestos

Verification of the presence of asbestos in vermiculite

Vermiculite insulation does not always contain asbestos, but it is necessary to have the vermiculite analyzed before starting any work. Indeed, if the vermiculite contains asbestos, the work may release asbestos fibres into the air and thus be a risk to health and workers.

Our technicians are trained and qualified to perform vermiculite sampling and analysis.

Radon in the air

The silent killer

Radon is a colorless, odorless and radioactive gas that can cause lung cancer. Radon concentration must be measured to identify a problematic situation.

Health Canada recommends taking a measurement over a minimum period of 3 months, but shorter-term measurements can also be considered in real estate transactions.

Dosimeters are analyzed in a laboratory approved by the National Radon Competence Program (PNCR-C / C-NRPP).

Breathable, inhalable, total dust

Concentration of dust collected


In the air, total dust (CAFN), breathable, inhalable or PM10 can affect the well-being of occupants or workers. That’s why it’s important to do some analysis.

We can perform gravimetric analyses that will allow us to determine the concentration of dust collected. In addition, our recognized standardized methods ensure reliable and precise results.

Other chemical analyses

Laboratory analysis of building contaminants

Whether for the analysis of lead in paint, beryllium on surfaces or for various chemical analyses in the air (volatile organic compounds [VOC], formaldehyde, ozone, welding fumes, metals, wood dust, silica crystalline, etc.), our trained professionals ensure samples are taken according to the standards in force.

For sample analysis, we work with certified laboratories to ensure rigorous and precise analysis.
