Geotechnical Investigation

Geotechnical Investigation

Geotechnical investigation identifies subsurface conditions to support safe and cost-effective design. We evaluate soil, rock, groundwater, and slope stability, providing the data needed for engineered mitigation, foundation design, and construction planning.

Overview

Field Investigation & Engineering Support

Accurate geotechnical data prevents undersized or failed stabilization systems, unexpected ground movement, costly redesigns mid-construction, and safety risks for the public and workforce.

Common applications include preliminary slope stability evaluations, foundation design for retaining walls, bridges, and structures, landslide risk assessments, and mining and industrial development.

Our capabilities include access-limited drilling for difficult terrain, coordination with engineers and geologists, detailed reporting and data collection, and integration with design-build stabilization solutions.

You need geotechnical investigation before constructing retaining or stabilization systems, when assessing a slope after movement is detected, or when designing foundations or deep ground improvements.

Questions

Geotechnical Investigation FAQ

Boring programs are site-specific. Simple slopes may need 2-3 borings; complex landslides may require 10 or more plus inclinometers. We design efficient programs that answer critical engineering questions.
Yes, we operate helicopter-portable and track-mounted drills that can access remote ridgetops, steep slopes, and locations with no road access. Our crews are experienced in difficult terrain operations.
Field work typically takes 1-2 weeks depending on scope. Laboratory testing adds 2-4 weeks. Engineering analysis and reporting can be expedited for urgent projects—we've delivered emergency reports within days.
Our reports include boring logs, laboratory test results, geologic cross-sections, stability analyses, and engineering recommendations. We can also provide CAD files, GIS data, and digital boring logs.
Yes, our investigation team includes CEGs (Certified Engineering Geologists) and licensed Professional Engineers. All field work is supervised by experienced geologists.

"When it comes to heavy foundation anchoring and stabilization projects, these guys are superb. Although the majority of the company's jobs involve heavy civil work, my project required their skills and specialized equipment for a challenging residential cliffside application. After careful review and critique of our plans, as well as assuring that expectations were fully understood, the work began on time and was completed ahead of schedule with minimal trauma along the way. In all, the job required the installation of ten horizontal deep rock anchors, several vertical piles, and shotcrete encapsulation. I highly recommend Rock Supremacy's services and would definitely use them again."

Residential Slope Stabilization
"We engaged Rock Supremacy for a very challenging cliffside project that involved the stabilization and reinforcement of a retaining wall which ultimately required a total of ten drilled horizontal rock anchors, multiple vertical stabilization pilings and encapsulation with concrete structural reinforcement. Even though my residential project, as large as it was to me, was of a much smaller scale than the company often deals with, it approached the task with all of the consideration and professionalism I could hope for. Notably, they were not hesitant to take on a challenging terrain even with its limited access. From the outset, Corey Muir was very engaged in the project and with finding workable solutions. He was eager to explore alternative options for accomplishing the goals and worked diligently with my engineering consultants to tweak the design for a practical, affordable solution. Throughout the planning process, he maintained excellent communications with myself and our structural engineers. Corey was careful to make sure, prior to our final agreement, that all details were fully understood. The company began the project exactly when anticipated. The on-site crew, David, Nate and Jules proved to be the "A" team. They are very skilled and professional. I found them considerate, easy to interact with, and flexible with regard to change possibilities. The team showed careful concern for my property and all possible avoidance of collateral damage while completing a job that involved some very heavy equipment. When the concrete supplier was unduly delayed, they took it in stride and made the best of the situation. The job was actually finished a little ahead of schedule. Definitely a five star rating for this group, I would be happy to further discuss my experience with anyone contemplating the use of Rock Supremacy's services."
