Groupe G²N Inc. is first and foremost…
A Quebec network of experts specialized in environment, geotechnics and laboratory analysis. Through its three divisions — Geostar, Notreau and GMT Lab — the group offers complete environmental quality management, from water to air, including soil and materials.
Born from a shared determination to raise industry standards, Groupe G²N Inc. brings together multidisciplinary teams of engineers, geologists, chemists, technologists and specialized technicians. Together, they share a single mission: analyzing with rigour to better protect, diagnose and build sustainably.
A comprehensive approach, from field to laboratory
One of the great strengths of Groupe G²N Inc. lies in the integration of its expertise. Geostar works in the field with environmental and geotechnical studies, drilling, sampling and site monitoring. Notreau, a laboratory recognized for over 20 years, ensures the analysis of drinking water, artesian wells and indoor air, in compliance with the strictest standards. GMT Lab completes this chain with specialized soil and construction-material analyses performed to ASTM, BNQ and LC standards.
This complementarity allows Groupe G²N Inc. to offer its clients comprehensive support, from sampling to interpretation of results, including laboratory validation. Each step is carried out with the same standards of quality, precision and transparency.
Expertise in the service of sustainable projects
Active in a bilingual regional market, Groupe G²N Inc. supports real estate developers, engineering and environmental firms, contractors, municipalities, institutions, businesses and individuals across Quebec. Whether the project is residential, commercial or institutional, the group is committed to providing reliable data and clear recommendations to support informed, responsible decisions.
Shared values, the same standard of excellence
Beyond technical expertise, Groupe G²N Inc. stands out for its human approach. Teamwork, scientific rigour, respect for standards and the environment, integrity and trust guide every intervention. This shared culture allows us to build lasting relationships with clients and partners while delivering accessible, responsive service tailored to real field needs.
By uniting the strengths of Geostar, Notreau and GMT Lab, Groupe G²N Inc. offers far more than services: it provides an integrated vision of environment and geotechnics, in the service of quality, public health and projects built on solid foundations.
