Our Scope of Work

Excavation Gérald Théorêt is a general contractor specializing in civil engineering and infrastructure projects across Greater Montreal, Montérégie, and surrounding areas. With decades of experience, we manage and execute excavation work, sewer and water main installations, and asphalt paving for roads, parking lots, and municipal developments.

As a general contractor, we coordinate every stage of a project: site studies, planning, excavation, pipe installation, backfilling and compaction, testing and compliance, and finishing (grading, paving, curbs). This integrated approach ensures strict control over timelines, costs, and risks while simplifying communication with a single point of contact.
