Sometimes, soil contamination is so extensive that a site cannot be decontaminated with excavation.

In these cases, an in situ treatment is necessary, which involves decontaminating soil and groundwater without first excavating the material to be treated.

Our Environment teams can support you with all your in situ decontamination needs.

At Nvira, our watchword for environmental disasters is responsiveness.

By being highly responsive and working with environmental solution experts, we are able to mitigate costs and the effects on the environment.

With our 24/7 emergency service, responsive measures and collaborative mindset, we are able to quickly implement proper protocols so that necessary contamination efforts can get underway.

At our ISO 9001:2016-certified analysis laboratory, we offer hundreds of tests to analyze and evaluate the quality of materials. Here are just some of the tests available to our clients:

• Sampling of aggregate sources
• Grading
• Petrographic analysis of aggregates
• Compressive concrete strength
• Compressive concrete strength test
• IPPG (pyrite swelling potential index) analysis
• Different analyses of clay materials
• Proctor tests
• Inherent characteristics of aggregates (Micro Deval and Los Angeles tests)
• Soil permeability

We also conduct a wide range of materials classification tests in accordance with CSA, ASTM, BNQ and LC standards.

It’s very important to ensure that the soil on your build site is suitable for your project. Our teams can advise you on the types and quantities of materials to use. We can perform the following soil analyses for your project:

• Soil bearing capacity
• Clay shear strength
• Water level on site
• Frost line
• Seismic site class
• Reuse of excavation materials
• Rock swelling potential
• Pavement structure to be implemented

Visual inspections have their limits, and a thorough air quality and industrial hygiene test can verify whether the indoor environment complies with the standards and requirements that apply to workplaces. Being proactive can help you prevent problems that impact the building or its occupants.

In addition, though the use of asbestos has declined significantly in Canada in the last few decades, it is still present in many office buildings. Materials that contain asbestos may pose a danger in the workplace, as anyone who inhales the fibres is at risk of developing serious health conditions. Our professionals can detect asbestos and guide you through the asbestos removal process.

Two provincial regulations apply when service stations cease operations. The first of these governs the removal of petroleum equipment licensed by the Régie du bâtiment du Québec (RBQ). The second regulation, part of the Environment Quality Act, stipulates that a site characterization study must be submitted to the Ministère de l’Environnement et de la Lutte contre les changements climatiques (MELCC) within six months of the closure. Our experts can walk you through all the legal requirements that apply under these regulations.

It is important to test soil quality before you buy land to make sure that it is not contaminated and that it is suitable for the construction work you plan to do. The combined expertise of our business lines allows us to coordinate the studies required by financial institutions for loan securitization. Our accredited experts are also able to offer a second opinion on studies conducted by third parties.

Founded in 2009, Groupe Petrosol is a petroleum industry expert and an environmental leader in Quebec. In 2018, Groupe Petrosol created Tecsol, its environmental services subsidiary, which also offers geotechnical and materials engineering expertise.

In 2019, Groupe Petrosol acquired Airmax Environnement, Habitair and Laboratoire Verdict in order to break into the hygiene, health and safety market.

Now, in 2020, the company has four distinct areas of expertise marketed under three different brands. Groupe Petrosol has announced that it will streamline its services under a single banner. Nvira is born.

Nvira Environment, formerly Tecsol, is supported by the same dedicated team of managers, engineers, professionals and technicians. The name change reflects the merging of Groupe Petrosol’s companies, which allow us to provide a more integrated service experience by bringing our diverse expertise under one roof.

In September 2020, Nvira was proud to announce the acquisition of the firm Terralpha, experts in landscape architecture! Since then, we can offer a new expertise to our clients: Landscaping architecture.

Hygiene, health and safety business line was created from the merger of Airmax Environnement, Habitair and Laboratoire Verdict with other Groupe Petrosol companies. Our clients can enjoy integrated service that draws on a range of expertise, according to the requirements of their project. Our managers, work teams and quality of work remain the same.

Nvira Energy is taking over Petrosol’s business segment within Groupe Petrosol. The new name reflects the merging of the group’s services. However, you will continue to be served by the same teams and leadership, who are able to provide improved service thanks to our new range of turnkey services that make even better use of our breadth of expertise.
