Heber City, Utah | Our Hometown
Excavation Contractor in Heber City, Utah
Residential and commercial excavation, site prep, utilities, septic, retaining walls and hauling from a crew that lives and works in the Heber Valley.
Local dirt work
Heber's hometown excavation company
Sierra Excavation was started by a family that grew up in Heber, and the Heber Valley is still where most of our work happens. We know the ground here: cobble and rock in some neighborhoods, high groundwater in others, steep lots on the benches and a building season that ends fast once the ground freezes.
That local knowledge helps on every type of project, whether you are a homeowner planning a new home, a builder lining up foundations before winter or a business owner preparing a commercial site. We are based right on US-189, so our crews and equipment are never far from your job.

Know the ground
Building on Heber Valley soil
Ground conditions change a lot across the valley. Some lots near the river bottoms deal with high groundwater, while the benches and foothills bring rock and steep grades. We plan for these conditions before we dig so foundations, drainage and utilities are built to last.
- Drainage and foundation drains for high groundwater areas
- Rock excavation on bench and foothill lots
- Erosion control on steep and freshly graded slopes
- Pre-freeze scheduling so foundations go in before winter

How much does excavation cost in Heber?
Cost depends on the size of the project, soil and rock, groundwater, access, utilities and how much material needs to be hauled. We provide free estimates after a site visit. Our excavation cost guide explains the main factors.
