Geotechnical investigation in Saanich must account for the region’s complex glacial geology, including marine silts, sensitive clays, and variable till deposits common to Vancouver Island. A thorough site characterization program typically begins with a Cone Penetration Test (CPT) to continuously profile soil stratigraphy and evaluate liquefaction potential under seismic loading. All fieldwork adheres to the Canadian Foundation Engineering Manual and relevant ASTM standards, ensuring data quality for foundation design and regulatory approvals.
Residential and commercial developments on sloping terrain or near coastal bluffs require detailed subsurface data to manage slope stability and bearing capacity risks. Integrating CPT testing with targeted borehole sampling provides the reliable geotechnical model needed for safe, cost-effective construction in this seismically active area.
