Geotechnical Survey



What is a Geotechnical Survey?

A geotechnical survey is a field investigation and analysis of soil, rock, groundwater, and other subsurface conditions on a site to assess its suitability for construction.

Why Geotechnical Surveys Matter in Real Estate

In Canadian real estate development and construction, geotechnical surveys identify potential risks and inform the design of foundations, retaining walls, and drainage systems.



Key elements:
  • Soil bearing capacity and composition
  • Groundwater table levels
  • Slope stability and erosion risks
  • Presence of contaminants or problematic soils



A geotechnical survey is often required before issuing building permits for new construction or significant redevelopments.

Example of a Geotechnical Survey in Action

The developer commissioned a geotechnical survey to ensure the soil could support the planned high-rise building.
