Geotechnical & environmental consulting

Ground truth, before you break ground.

Geotechnical investigation, environmental assessment, and subsurface consulting for infrastructure, energy, and mining projects across the Mountain West.

Where we work in the ground

Four practice areas, one field crew. Every report is stamped by a licensed engineer or geologist who was on-site.

Geotechnical Engineering

Subsurface investigation, foundation design, and slope stability analysis for infrastructure and commercial development.

Environmental Geology

Phase I/II site assessments, contamination delineation, and regulatory compliance support.

Mining & Subsurface Consulting

Resource characterization, tailings geotechnics, and permitting support for mining operations.

Materials Testing

ASTM- and AASHTO-compliant soil, aggregate, and concrete testing from our in-house laboratory.

Transportation / Infrastructure

I-70 Mountain Corridor Widening

Slope stability analysis and rockfall mitigation design for a 6-mile mountain corridor widening, keeping the project on its permitting timeline.

Energy

Antelope Ridge Wind Farm

Foundation design recommendations for 42 turbine pads across variable bedrock, informed by seismic refraction survey.

Mining

Copper Basin Tailings Expansion

Tailings storage facility geotechnical characterization and stability analysis supporting a state dam-safety permit.

How a project runs

01
Investigate
Site reconnaissance, drilling, and field sampling calibrated to the geology and the question at hand.
02
Analyze
Laboratory testing and engineering analysis translate field data into design parameters.
03
Report
A stamped report that holds up in front of a permitting board or a lender's due-diligence review.
04
Support
Construction-phase observation and as-built consultation through substantial completion.

“Stratum's borings program found the fault splay our first consultant missed — a year before we broke ground, not after.”

Dana Reyes— VP of Engineering, Continental Rail Partners

Talk to a geologist before you talk to a permitting board.

Tell us about the site and the timeline. We'll scope the investigation and get a proposal back within a week.
