Drilled Piers in Utah and Arizona

For over two decades, Hark Drilling has delivered drilled pier construction across the Intermountain West, supporting commercial, industrial, and infrastructure projects from the Wasatch Front to the Sonoran Desert. With offices in Salt Lake City and Phoenix, our crews are equipped to handle the full geotechnical range of the region.

When Drilled Piers Are the Answer

Drilled piers, also called drilled shafts or drilled caissons, are deep foundation elements that transfer structural loads through unstable surface soils into stronger, load-bearing subsurface layers. The process involves drilling a large-diameter shaft (typically greater than 24 inches), setting a custom rebar cage, and placing high-strength concrete to form a solid foundation column built to last.

Drilled Pier Construction Capabilities

Our fleet ranges from large-diameter rigs suited for open commercial sites to compact equipment built for low-overhead clearance and rugged desert terrain. We install drilled concrete piers from 18 inches to 12 feet in diameter, reaching depths of 100 feet or more. Every project is grounded in engineered planning, whether we're executing your engineer's design or working with our trusted engineering partners to develop a tailored solution.

Pier Foundations

With a fleet that ranges from equipment suitable for large, open commercial sites to rigs that can maneuver in low overhead clearance areas and rough desert terrains, Hark Drilling can tackle projects of any scale. Our capabilities include drilling diameters from 18 inches up to an impressive 12 feet, reaching depths of over 100 feet. Our highly experienced drilled shaft contractors can handle any size and scope of drilled pier project.

Comprehensive Drilled Pier Services

Hark provides a full scope of work to deliver complete drilled pier installations:

• Site analysis and drilling: subsurface evaluation through shaft excavation

• Rebar cage fabrication and placement: custom-built reinforcement to spec

• Concrete placement: methods tailored to soil and groundwater conditions

• Augered Cast-in-Place (ACIP) piles: for tighter sites or specific load profiles

• Material handling and spoils management: clean, organized job sites from start to finish

• Drilling-only services: available when the project scope calls for it

We coordinate seamlessly with related work like shoring, micropiles, and soil stabilization when a project calls for an integrated foundation approach.

Applications of Drilled Piers

Drilled piers provide critical support for:

Commercial and mixed-use buildings

High-rises, towers, and skyscrapers

Industrial pads and mining infrastructure

Power transmission, signage, and billboard foundations

Bridge abutments and DOT projects

These foundations are particularly beneficial in areas where surface soils lack sufficient load-bearing capacity. By distributing weight deeper into the ground, drilled piers ensure stability and long-term reliability for your projects.

Regional Expertise Across Utah and Arizona

Subsurface conditions vary widely across the Intermountain West, and so does our approach. In Utah, including Salt Lake, Utah, Davis, Weber, and Washington counties, projects often involve cobbles, dense bedrock, and the high water tables of the Wasatch Front. In Arizona, the expansive clays and caliche common across Maricopa, Pima, and Coconino counties demand careful moisture control and disciplined drilling technique.

Drilled Piers | Frequently Asked Questions

What does a drilled pier cost?

Pricing depends on shaft diameter, depth, soil conditions, site access, and reinforcement requirements. We provide detailed estimates after reviewing geotechnical data for your project.

FAQ image

How long does drilled pier construction take?

Most individual piers are drilled and poured within a single shift. Larger projects are sequenced to keep your overall construction timeline on track.

FAQ image

What equipment is used for drilled piers?

We deploy track-mounted and crane-mounted drill rigs sized to project specs and site access, including low-clearance equipment for constrained urban sites.

FAQ image

What access is needed for drilled pier work?

Requirements vary by rig. We assess access during site planning and select equipment accordingly, so even tight or remote sites stay buildable.
