Overview
Engineered Excavation Support
Every commercial excavation that cuts below grade near existing structures, utilities, or property lines requires an engineered shoring system. The right retention method depends on excavation depth, soil conditions, groundwater, surcharge loads, and whether the system needs to be temporary or permanent.
Rocky Mountain Micropiles provides complete shoring and earth retention services — from initial design coordination through installation and monitoring. We work with your engineer of record or provide design-build solutions, selecting the optimal combination of soldier piles, soil nails, tieback anchors, and shotcrete facing for each project’s specific conditions.
Our drill-and-grout approach to shoring installation eliminates impact driving, minimizes vibration near adjacent structures, and allows us to work in the constrained site conditions typical of Utah’s urban and suburban commercial construction.
Our Systems
Retention Systems We Install
We select and combine these systems based on your project’s excavation depth, soil conditions, and performance requirements.
Steel H-piles drilled and grouted at regular spacing before excavation. Timber lagging or shotcrete placed between beams as the cut progresses. The most common commercial shoring system — reliable, cost-effective, and adaptable to most soil conditions.
Learn More →Steel bars drilled and grouted into the excavation face at designed spacing, connected to reinforced shotcrete facing. Built from the top down as the excavation progresses — no pre-installation needed. Ideal for cut slopes, permanent walls, and projects where the in-situ soil can maintain a temporary face.
Learn More →Drilled and grouted steel tendons post-tensioned to provide active lateral restraint to soldier piles or sheet piles. Used for deeper excavations where cantilever capacity alone is insufficient. Each anchor is proof-tested to verify design load before lockoff.
Learn More →Reinforced shotcrete applied over welded wire fabric or rebar to create the structural facing for soil nail walls and permanent soldier pile systems. We coordinate shotcrete application with our nail and pile installation to maintain the excavation schedule.
Applications
When You Need Shoring
Engineered shoring is required any time an excavation creates an unsupported soil face that could affect worker safety, adjacent structures, utilities, or roadways.
Discuss Your ProjectBelow-Grade Commercial Construction
Parking garages, basements, mechanical vaults, and foundation excavations for commercial buildings requiring retention on one or more sides.
Urban Infill & Property Line Excavations
Excavations tight to property lines where conventional sloping isn’t possible. Shoring allows vertical cuts while protecting neighboring improvements.
Highway & Infrastructure Cuts
Retention for road widening, interchange construction, and utility corridor excavations where adjacent traffic and infrastructure must remain in service.
Permanent Grade Changes
Permanent retaining walls for site development, hillside building pads, parking lot terracing, and grade separations between adjacent properties.
Emergency Stabilization
Rapid response shoring for excavation collapses, slope failures, and emergency retention situations requiring immediate stabilization.
Existing Wall Repair & Reinforcement
Reinforcing failing retaining walls, adding capacity to under-designed systems, and retrofitting walls to handle increased loading from new construction.
Our Process
From Plans to Performance
We coordinate closely with your GC and engineer to keep shoring installation ahead of the excavation schedule.
Plan Review
Review geotechnical report, structural plans, excavation depths, and adjacent conditions to determine the best shoring approach.
System Selection
Recommend soldier piles, soil nails, tiebacks, or a combination — based on soil type, depth, schedule, and budget.
Install Shoring
Drill, grout, and install the shoring system. We coordinate with the excavation contractor to keep the project on schedule.
Test & Verify
Pull-out tests on nails, proof tests on tiebacks, and monitoring data verify the system meets design requirements at each stage.
Documentation
Complete installation records, test reports, grout logs, and as-built documentation delivered to the engineer and GC.
Why Us
The Rocky Mountain Micropiles Advantage
We’re a specialty geotechnical contractor focused exclusively on drilled and grouted systems — not a general contractor doing shoring on the side.
Drill & Grout Specialists
This is all we do — drilled and grouted geotechnical systems. Every crew, every rig, every project is focused on this specialty. You get depth of experience, not a generalist learning on your job.
Multiple Systems, One Sub
Soldier piles, soil nails, tiebacks, and micropiles — all from one subcontractor. Simplifies coordination, reduces mobilizations, and provides a single point of responsibility.
Schedule-Driven Execution
We understand that shoring is on the critical path. Our crews mobilize quickly and coordinate directly with the excavation contractor to avoid delays.
Local Wasatch Front Knowledge
We know Utah’s geology — the expansive clays, collapsible soils, cobble zones, and variable bedrock. That local experience translates to fewer surprises and more accurate proposals.
