Highway cut rippability
A DOT needs to know how much rock must be blasted. Refraction lines along the alignment map where velocities exceed ripping thresholds, cutting the uncertainty in the excavation bid.
Applications
Engineering & Geotechnical
Subsurface conditions for infrastructure and construction.
Borings tell you what is at a point. Geophysics tells you what is between the borings. We map bedrock depth, weak zones, voids, stiffness and rippability so engineers can place borings wisely, reduce change orders and design foundations with confidence.
Drone-enabled
What we map
- Depth to bedrock and rippability
- Shear-wave velocity and seismic site class
- Soft zones, voids and old fill
- Landslide slip surfaces
- Corrosivity (soil resistivity)
What you receive
- Velocity and resistivity sections tied to borings
- Vs30 and site class
- Soil resistivity for grounding and corrosion design
- Targeted boring recommendations
Recommended methods
- Seismic Refraction & Reflection — Velocity and layering for engineering
- MASW & Passive Seismic — Shear-wave velocity profiles
- Electrical Resistivity Tomography — 2D and 3D resistivity imaging
- Ground Penetrating Radar — High-resolution shallow imaging
- Drone LiDAR & Photogrammetry — Terrain models and orthomosaics
- Gravity — Density contrasts at depth
Examples
Solar farm grounding
A solar developer needs soil resistivity for grounding design. Wenner soundings and ERT across the site give layered resistivity models for the electrical engineer.
