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.
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.
This service supports our solutions for:
Tools & Technology
We deploy specialized equipment matched to project requirements and site conditions.
How We Do It
Proven methods and specialized techniques that deliver reliable, long-lasting results.
Horizontal Drains
Horizontal drains are drilled drainage systems designed to lower groundwater pressure and improve the stability of slopes, embankments, and rock faces. By relieving pore pressure, these drains significantly reduce the risk of landslides, sloughing, and long-term slope movement.
Micropiles
Micropiles are small-diameter, high-strength deep foundation elements used to transfer loads into competent ground. Their versatility makes them ideal for underpinning, slope stabilization, and situations with limited access or difficult geology.
Soil Nailing
Steel bars driven into soil to reinforce and stabilize loose ground or slope faces.

What Our Clients Say
We take pride in building lasting relationships with our clients through exceptional service and results.
"It amazes me how quick these guys adapt to challenging and seemingly overwhelming construction situations in the best, and most creative approach. Very smart, dedicated, hardworking group of brave workers in hazardous work sites. Not the type of work just anyone can do! Keep up the good work!"
"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."
"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."
