Geotechnical Expertise
Geotechnical engineering is a critical step in any construction project. It helps anticipate soil-related risks and design foundations that ensure the stability, durability, and safety of the structure.
Without a geotechnical study, underground uncertainties can lead to cost overruns, delays, or serious structural issues.
At Groupe SBSE, we put our expertise to work to analyze soil conditions, design appropriate
technical solutions, and support you from preliminary studies through to construction.
Our work is grounded in key standards such as the National Building Code, the Canadian Foundation Engineering Manual, and the MTQ Road Structures Standards collection.
Geotechnical Services at Groupe SBSE
We carry out soil studies, diagnostics, monitoring, and technical support to secure your projects and ensure their long-term durability, regardless of their nature or environment.
Our approach is built on in-depth mastery of Canadian standards (NBC, CSA, ASTM, etc.), proven responsiveness in the field, and a strong commitment to client success.
Our geotechnical engineers have extensive knowledge of Canadian soil types, including glacial soils, sensitive clays, tills, and organic deposits and operate across a wide range of settings: urban, rural, coastal, and northern regions.
