Retaining Walls
Retaining walls hold back earth, create usable space, and protect infrastructure. Whether you need a wall to stabilize a failing slope, support a new building excavation, or maximize developable land on a hillside lot, Rock Supremacy delivers engineered retaining wall solutions that perform for decades. As experienced retaining wall contractors and engineers, we handle everything from design through construction—soil nail walls, mechanically stabilized earth (MSE) walls, soldier pile walls, and gravity walls. Our design-build approach means faster delivery, clearer accountability, and walls that are built to last 75-100 years.
Complete Retaining Wall Services
The right retaining wall depends on the height, soil conditions, loading, drainage, aesthetics, and budget. Our engineering team evaluates these factors and designs the most cost-effective wall system for your specific situation.
Soil nail walls are our most common retaining wall system for cuts. As excavation proceeds, we install drilled steel bars (nails) into the retained soil and apply shotcrete facing. Soil nail walls are typically 25-50% less expensive than cantilever concrete walls and construct faster because they're built top-down as you excavate. We've built over 10 miles of soil nail walls across the Western U.S.
MSE walls (mechanically stabilized earth) use layers of reinforcement within compacted fill to create a stable earth structure. MSE walls are ideal for fill slopes, highway embankments, and bridge abutments. The facing can be concrete panels, modular blocks, or wire mesh with vegetation.
Soldier pile walls consist of steel beams with lagging installed between them. For taller walls, we add tieback anchors drilled into stable ground behind the wall. Soldier pile walls work well in urban areas where property lines are tight.
Gabion walls use wire baskets filled with rock to create permeable gravity walls. Gabions are economical, drain well, and blend naturally into landscapes.
For walls that need to look like natural rock, we apply sculpted shotcrete finishes that replicate stone, timber, or other textures. Our sculpted walls have won design awards and satisfy even the most demanding aesthetic requirements.
Every retaining wall we build includes proper drainage. Water behind a wall is the leading cause of failure. We install drainage aggregate, geocomposite drains, and weep holes to ensure hydrostatic pressure never builds to dangerous levels.

How We Do It
Proven methods and specialized techniques that deliver reliable, long-lasting results.
Concrete/Sculpted Shotcrete Finishes
Sculpted shotcrete creates natural-looking rock surfaces on stabilized slopes, retaining walls, and landscape features. Artistic carving and staining transform functional shotcrete into aesthetic elements that blend with surrounding geology.
Gabion Baskets
Gabion baskets are wire-mesh containers filled with rock that create flexible, permeable retaining structures. They're widely used for erosion control, slope stabilization, channel protection, and retaining walls where drainage and adaptability to settlement are essential.
Mechanically Stabilized Earth (MSE) Walls
MSE walls are reinforced soil retaining structures built using engineered backfill and steel or geosynthetic reinforcement layers. Faced with precast panels, welded wire baskets, or vegetated facings, MSE walls provide cost-effective, flexible earth retention for infrastructure and commercial projects.
Soil Nailing
Steel bars driven into soil to reinforce and stabilize loose ground or slope faces.
Soldier Pile Walls
Soldier pile walls are proven earth retention systems for stabilizing deep excavations and steep slopes. Steel beams installed at intervals with lagging placed between them provide flexible, economical support that adapts to site constraints.
Structural Shotcrete
Structural shotcrete is high-strength, reinforced concrete applied pneumatically to create durable retaining walls, tunnel linings, and slope support systems. Engineered to carry significant loads, it provides monolithic construction that conforms to irregular surfaces.
Tieback Anchors
Tieback anchors provide active lateral reinforcement for retaining walls, excavation support systems, and slope stabilization by transferring loads deep into stable ground or rock. These post-tensioned elements are essential for deep excavations and high-load applications.

Retaining Walls FAQ
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."
