Helical Piles in Utah

Utah's foundation problems start in the soil. The Utah Geological Survey says that expansive clayey soils can swell with enough force to crack walls and foundations of light residential structures, and that collapsible soils lose volume when wet, which can cause subsidence and structural damage. Collapsible soils are typically associated with young alluvial fans, debris flows, and loess.

Both conditions move with moisture, which is why irrigation, leaking pipes, and heavy precipitation can trigger settlement. Helical piers address this by bypassing the problem layer and bearing on firmer soil below it. Because they are screwed in with hydraulic equipment, they also suit finished yards and hillside lots.

Common uses in Utah

• Underpinning homes that have settled on expansive or collapsible soil
• Foundations for additions, garages, and accessory dwelling units
• Deck, patio, and pergola footings in backyards with limited access
• Ground-mount solar arrays on open land
• Retaining wall and slope-stabilization support on hillside lots
• Light commercial canopies, signs, and equipment pads

Installers drive piers with hydraulic torque heads, and the engineer sets the depth and the installation torque that must be reached before a pier is accepted.

Soil, frost depth, and code considerations

Frost depth varies with elevation. Salt Lake City's design criteria list a 30-inch frost depth and adopt the 2021 International Residential Code. Higher mountain towns can differ, so check the local table. Utah's residential code is the Utah Residential Code 2021, based on the 2021 IRC with state amendments.

Manufacturers typically document helical pile capacities through ICC-ES evaluation reports issued under acceptance criteria AC358, and the city or county building department issues the permit. In Utah, a geotechnical investigation is often the first step, because the Utah Geological Survey recommends one by licensed professionals before building on problem soils.

Typical helical pier costs in Utah

Nationally, helical piers typically run about $2,000 to $4,000 each installed, with an average near $3,000 per pier, according to Foundation Repair HQ. The same guide notes that hand-digging around landscaping or structures can add $200 to $500 per pier. Utah jobs can land anywhere in that range depending on how deep the stable layer is, how many piers are needed, and site access. See our helical pier cost guide for a breakdown.

Find a helical pile installer in Utah

The listings below cover installers, foundation repair companies, manufacturers, and distributors that serve Utah. Many work along the Wasatch Front, including Salt Lake City, Provo, and Ogden, and in St. George. Compare service areas, ask whether the crew installs to an engineer's torque specification, and request copies of installation logs.

Utah helical pile FAQs

Do helical piers work in Utah's expansive clay?

Yes, when they are designed for it. The helix plates are set below the zone where clay swells and shrinks, so the pier bears on soil that stays more stable. The engineer also accounts for uplift that swelling clay can exert on the shaft.

Do helical piers help with collapsible soil?

They can. Collapsible soil settles when it gets wet, so piers are designed to carry the load to deeper, stable material instead of relying on the surface layer. A geotechnical report identifies how deep that layer is.

Do I need a permit for helical piers in Utah?

Most Utah cities and counties require a permit for foundation repair, additions, and new structures. Rules differ by jurisdiction, so confirm with your local building department before work starts.
