Rock Anchoring

Rock Anchoring

Rock anchors (bar or strand) provide high-capacity tensile support for retaining systems, stabilization measures, and structural foundations. Anchoring ensures long-term stability in difficult geology, variable rock mass conditions, and steep or constrained project sites.

Overview

Anchor Installation & Testing

Anchors transfer loads deep into competent ground, preventing wall deformation, slope movement, structural overstress, and failure under surcharge loading.

Common applications include soldier pile and H-pile walls, slope stabilization, bridge abutment reinforcement, high-load retaining structures, and mining and industrial stabilization.

Our capabilities include drilling in fractured or blocky rock, bar and strand anchor installation up to high capacities, testing and certification, and rope-access anchoring on steep slopes.

You need rock anchoring when walls are over 10-15 feet tall, high loads or surcharge forces are present, surface rock or soil conditions are poor, or steep slopes or excavations need stabilizing.

Questions

Rock Anchoring FAQ

Rock bolts are typically shorter (5-30 feet), smaller diameter, and used to stabilize rock masses. Ground anchors (tiebacks) are longer (30-200 feet), higher capacity, and transfer loads deep into stable ground. We use each where appropriate.
Every anchor is proof-tested to 133% of design load per PTI standards. Performance tests on sacrificial anchors verify bond strength and creep behavior. We provide complete test documentation for all installations.
With proper corrosion protection (Class I or II systems), permanent anchors are designed for 75-100 year service life. We use double corrosion protection systems including encapsulation, grout, and sheathing.
Yes, we install anchors in everything from hard granite to soft sedimentary rock. Bond lengths and grouting methods are adjusted based on rock quality. Weaker rock simply requires longer bond zones.
Post-tensioning applies a predetermined load to the anchor after installation, actively compressing the rock mass or structure. This prevents movement before it starts, rather than reacting to movement after the fact.

"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."
