Excavation Services in Sandy, UT

Sandy is a city of contrasts when it comes to excavation. The western half, anchored by the Sandy Civic Center area and the I-15 commercial corridor, offers flat terrain and relatively straightforward clay-soil digging. The eastern half, climbing toward the mouths of Big Cottonwood and Little Cottonwood Canyons, presents some of the most challenging residential excavation terrain in the entire Salt Lake Valley. AccuRite Excavation has experience across the full range.

Glacial Moraine: Sandy’s East Side Story

The Cottonwood Canyons were carved by glaciers during the last ice age, and those glaciers deposited enormous quantities of rocky material at their mouths as they retreated. Sandy’s eastern neighborhoods — Granite, the areas east of 1300 East approaching the canyon mouths, and the streets climbing toward Snowbird and Alta — sit directly on this glacial moraine.

This isn’t ordinary rocky soil. Moraine deposits contain everything from fine sand to granite boulders the size of pickup trucks. There’s no predicting exactly where the boulders are until you’re digging. A foundation trench might go smoothly for twenty feet and then hit a six-ton boulder that has to be broken or hauled out.

We approach east Sandy projects knowing that rock hammering is likely and boulder removal is possible. Our equipment includes hydraulic hammers for breaking rock and machines with enough lift capacity to handle oversized material. Timelines for foundation digs on the east side account for the reality that some days you move less material than planned because the ground had something to say about it.

The Drainage Advantage

There’s an upside to the glacial deposits. This rocky, sandy material drains extremely well. Properties on Sandy’s east side rarely have the water table and drainage problems that plague the valley floor. Foundations stay dry, basements don’t leak, and the soil doesn’t expand and contract with moisture the way Bonneville clay does. The material is harder to dig but better to build on.

Sandy Civic Center and the Valley Floor

The Sandy Civic Center area, the TRAX line corridor, and the neighborhoods west of 700 East sit on the Salt Lake Valley floor. The soil here is Bonneville clay and silt — the same material that underlies the entire valley west of the benches.

Excavation on the valley floor is straightforward in terms of material. The clay moves without hammering and the terrain is flat. The challenges are the clay’s moisture reactivity and, in low-lying western Sandy areas approaching the Jordan River, a moderate water table.

Commercial development along the State Street corridor and the TRAX-adjacent areas generates steady demand for site prep, foundation work, and demolition of older commercial structures being redeveloped. We handle commercial excavation at the scale these corridor projects require.

The 9400 South Corridor

The 9400 South corridor is one of Sandy’s primary commercial arteries, and the transition from flat ground on the west to hilly terrain on the east happens along this stretch. Properties at the 9400 South and Highland Drive intersection face different soil conditions than properties at 9400 South and State Street, even though they’re on the same road. We’ve worked both ends and adjust our approach accordingly.

Retaining Walls on the East Side

Sandy’s east side is wall country. The steep lots approaching the Cottonwood Canyons need retaining walls for building pads, driveways, yard terracing, and slope stabilization. We build walls as an integrated part of the excavation project because the wall needs to go in while the equipment is on-site and the grades are exposed.

Natural rock walls are popular in this area — the granite and quartzite sourced from local quarries complement the canyon setting. For taller structural walls, engineered segmental block with geogrid reinforcement handles the loads. We’ve built walls up to twelve feet in Sandy’s foothills, often in tiered configurations that manage grade changes of fifteen feet or more across a property.

Residential Excavation Across Sandy

Whether it’s a new custom home on an east-side canyon lot or an addition to an existing home in the Crescent View area, residential excavation is our core Sandy service. The specifics change with the terrain:

• East side canyon lots: Rock hammering, boulder removal, extensive retaining walls, hillside drainage
• Central Sandy neighborhoods: Mixed soil, some rock on the upper streets, moderate grading needs
• West side and valley floor: Clay management, compaction, drainage-focused grading

We price each project based on its actual location and soil conditions, not a city-wide average.

Utility Work and Infrastructure

Sandy’s established neighborhoods have aging utility infrastructure that needs periodic replacement. Original sewer laterals, water service lines, and storm drains wear out, and we handle the underground utility excavation for their replacement. In the east-side rocky terrain, utility trenching is significantly more work than on the valley floor — bedding material is essential because the native boulder-strewn ground doesn’t support pipes well.

Serving Sandy and South Salt Lake Valley

Sandy borders Draper to the south, Cottonwood Heights to the north, and Midvale and Murray to the northwest. We work throughout the south Salt Lake Valley. From our Ogden base, Sandy is about a 45-minute drive south on I-15, and we stage equipment locally for multi-day projects.
