Local conditions
Geotechnical conditions in Utah County
Utah County sits in an active seismic region along the Wasatch Front, where the underlying geology transitions from lake-deposited silts and clays on valley floors to alluvial fan gravels and colluvial soils at the base of the Wasatch Range. Those conditions vary sharply across a single site, which makes verified subsurface data essential before any foundation design moves forward. Expansive soils, collapsible lake sediments, and shallow groundwater are documented concerns across parts of the valley that affect bearing capacity, settlement potential, and lateral earth pressure. Our geotechnical team provides subsurface investigations, laboratory soil testing, and written geotechnical reports that give your structural and civil engineers the parameters they need to design with confidence. Work in Utah County is dispatched from our Salt Lake City regional hub, approximately 39 miles from the county core, and scheduled in coordination with your project timeline. The laboratory supporting this work operates under a documented quality system.
Valley floor soils in Utah County frequently include fine-grained lake sediments with variable consolidation characteristics and sensitivity to moisture change — conditions that warrant careful attention to bearing capacity and settlement in foundation design. Freeze-thaw cycles during winter months can also influence near-surface soil behavior and should be factored into grading and earthwork schedules.
FAQ · Utah County
Utah County has a lot of alluvial fan terrain near the mountains — does that affect how you plan a boring program?
Yes. Alluvial fan deposits are typically heterogeneous, with abrupt lateral changes in grain size and density over short distances. We adjust boring spacing and depth to account for that variability rather than applying a uniform grid. Subsurface exploration follows ASTM D1586 for Standard Penetration Testing or ASTM D3550 for driven samplers depending on material conditions, with sample recovery reviewed in context of the depositional environment.
My project is in a low-lying valley area. Should I be concerned about expansive or collapsible soils?
Low-lying areas in the Utah County valley can contain fine-grained lacustrine deposits that are susceptible to consolidation settlement under load or collapse upon wetting. Laboratory testing including ASTM D4546 for one-dimensional consolidation and ASTM D2435 for compressibility helps quantify that risk. The geotechnical report will document whether mitigation — such as over-excavation, surcharging, or engineered fill — is warranted for your foundation type.
Utah County is in a seismically active zone. Will the report address liquefaction and seismic site classification?
Yes. The Wasatch Front is one of the more seismically active areas in the intermountain west, and IBC 2021 (as adopted in Utah) requires seismic site classification per ASCE 7. Where saturated, loose granular soils are encountered, we evaluate liquefaction potential using SPT-based procedures. The report will document the site class and, where applicable, liquefaction susceptibility findings and recommended design parameters.
