Our environmental services extend to geo-environmental expertise. This discipline draws on multiple engineering specialties to produce comprehensive environmental impact studies and environmental health reports at every project stage.

Our geological engineers examine the impact of human interactions (e.g., pollution and waste management) and natural risks on the environment being studied. Our team of hydrogeological engineers assesses contaminated water and develops solutions to treat it and prevent it from spreading and contaminating nearby groundwater and water tables.


Our teams of engineers and professionals complete assessments and analyses of natural environments that may be at risk during a project. We assess potential risks and impacts following a strict method that allows us to make reliable projections. Our analyses help us quickly identify risks to the environment and to the health of people visiting the studied site.

Our services prevent serious health risks caused by site contamination and help our clients meet applicable national, provincial and municipal standards.



Tecsol becomes Nvira

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 will allow us to provide a more integrated service experience by bringing our diverse expertise under one roof.
