Last spring we reviewed a commercial site off Rue Notre-Dame where the client had already poured footings. The concrete was in place, but the bearing stratum was inconsistent—lenses of soft silty clay left from the ancient Champlain Sea intermixed with glacial till. Repentigny sits on these complex post-glacial deposits, and assuming uniform conditions across a 2,000 square meter lot is a gamble you do not want to take. A proper soil mechanics study maps that variability before steel is cut or formwork goes up. We extract undisturbed samples, run the full suite of index and strength tests, and deliver parameters you can plug directly into your structural model—no guesswork, no last-minute redesigns. When the stratigraphy is tricky, we pair the lab program with field investigation like test pits to visually confirm layer boundaries and groundwater depth.
Settlement, not bearing failure, governs most foundations on the Champlain clays found across Repentigny's Lanaudière terraces.
