Geotechnical Engineering Services in Brandon Manitoba

Brandon soils commonly consist of silty clay to clay till near the surface, with shallow groundwater. These clay soils can be highly plastic and sensitive to moisture changes, which may cause swelling or shrinkage. For residential foundations, we recommend a geotechnical investigation to determine bearing capacity, frost depth, and the need for drainage measures. Proper site preparation and foundation design are essential to avoid future movement or cracking.

In Brandon, the frost depth is typically around 1.8 to 2.4 metres, depending on soil type and exposure. Foundations must be placed below this depth to prevent frost heave. We also recommend installing perimeter drainage and using non-frost-susceptible backfill materials. Our investigations include frost susceptibility testing and recommendations for foundation insulation if needed, ensuring long-term stability.

The primary code is the National Building Code of Canada (NBC) 2020, adopted with provincial variations by Manitoba. For foundation design, we follow the Canadian Foundation Engineering Manual (CFEM). Site-specific seismic hazard is assessed per NBC, though Brandon is in a low seismic zone. All soil testing follows ASTM standards, and our reports meet the requirements of local authorities having jurisdiction.

A typical investigation includes drilling boreholes to depths of 6 to 15 metres, performing Standard Penetration Tests (SPT), and collecting soil samples for laboratory testing (moisture content, Atterberg limits, grain size, and consolidation). We also install monitoring wells to measure groundwater levels. Based on results, we provide foundation recommendations, settlement estimates, and construction considerations such as shoring and dewatering.
