Keller Group
Our team delivers deep foundations, excavation support, ground improvement, and grouting solutions tailored to the region's complex subsurface conditions, including sensitive Champlain Sea clay deposits and variable soil profiles. Based in Ottawa, Keller supports projects throughout Eastern Ontario and the National Capital Region.
Geotechnical expertise in Ottawa
Ottawa presents unique geotechnical challenges due to the presence of sensitive Champlain Sea clay deposits throughout much of the region. Keller's local teams have experience addressing:
- Highly sensitive marine clay soils
- Settlement and differential movement risks
- Infrastructure and transportation projects in soft ground conditions
- Urban development within constrained environments
- Foundation performance in variable subsurface conditions

Featured projects
Infrastructure
Ottawa Light Rail Transit
When a significant sinkhole developed above the Ottawa Light Rail Transit (OLRT) tunnel, Keller worked on an aggressive construction schedule in limited working space.
Infrastructure
Kanata West Pumping Station
Keller developed, designed, and constructed the optimal solution using multiple techniques to meet the project requirements.
Institutional
Carleton University Student Residences
When ground conditions differed, Keller provided value engineering and offered a design build solution for new student housing.
