Geophysical Analysis and MASW Studies to Build the Most Accurate Geological Model
Suspect a problematic area? Cavities or remnants of old industrial foundations? Need to monitor variations in bedrock, delineate or assess the depth of an aquifer, or quantify seismic risk?
Whenever anomalies are suspected, Enviroc Groupe Fondasol combines standardized geophysical studies with geotechnical tools—such as the pressuremeter—to produce a precise geological profile. This ensures optimized recommendations.
Our Expertise at a Glance
More Comprehensive Field Data—Without Multiplying Boreholes
Our teams combine MASW (Multichannel Analysis of Surface Waves) surveys with geotechnical exploration and testing campaigns in order to:
- Detect anomalies (cavities, voids, buried structures);
- Accurately position structures;
- Optimize foundation design and avoid unplanned corrective work.
MASW Surveys for Seismic Risk Management
The MASW method is a non-intrusive technique that measures surface waves (Rayleigh waves) using geophones placed in the field. The result: a 2D subsurface cross-section showing wave velocity and soil stiffness, enabling:
- Seismic site classification (per NBC and the Québec Construction Code);
- Validation or refinement of empirical assumptions;
- Anticipation of mitigation measures (deep foundations, compaction, rigid inclusions).
This method is especially valuable for projects in seismic zones (such as Québec), as it directly impacts structural design, foundation costs, and local amplification risk.
MASW analysis is often combined with our other services:
- Geotechnical studies (design support)
- Roadway rehabilitation studies (better reading of existing layers)
- Slope stability studies (shear strength and cohesion analysis)
- Geotechnical expertise (diagnostics or corrective measures)
