Steel Rated for Utah Ground
Our helical piers are galvanized to resist corrosion and rated for the load requirements typical of Utah's clay, rocky, and mountain soils.

Helical Pier Installation for Utah Decks and Pergolas
Build on a foundation that grips Utah's shifting soil from day one. Mountain West Fence & Deck Supply installs helical piers for deck builders and homeowners across the Wasatch Front.
Why Choose Us
What Are Helical Piers and Why Utah Projects Need Them?
A helical pier is a galvanized steel shaft with one or more helical blades that screws directly into the ground, similar to a large screw, until it reaches load-bearing soil below the frost line. Once installed, it becomes a permanent, non-shifting support point for deck posts, pergola footings, or steel deck framing, without the digging, forming, or multi-day cure time a concrete footing requires.
Any deck installation is only as strong as what sits underneath it, and Utah's ground gives foundations a hard time. Expansive clay soils near Saratoga Springs and Utah Lake swell and shrink with moisture, while rocky, sloped lots around Park City and Heber City make traditional excavation slow and expensive. Homeowners setting posts for a wood pergola, fiberglass pergola, or aluminum pergola often choose helical piers over buried posts specifically because the piers won't heave or shift as the ground freezes and thaws each winter.
As a fence company and deck builder supply source that's served the Wasatch Front since 1989, we stock helical piers alongside ground screws for lighter-load applications, so you can match the foundation to the project instead of forcing every job into a one-size-fits-all footing.
Benefits of a Helical Pier Foundation
Choosing a helical pier system over a poured footing changes what your project timeline and long-term maintenance look like. Here's what Utah homeowners and contractors gain:
- No concrete curing time, so framing and deck construction can continue the same day
- Rated below Utah's frost line, resisting heave through repeated freeze thaw cycles
- Minimal excavation, a practical choice for tight yards, sloped lots, or landscaped areas
- Load tested during installation, so the foundation's rating is confirmed before framing begins
- Compatible with steel deck framing, aluminum deck framing, or traditional wood post construction
- Pairs well with a RainEscape deck drainage system to keep the space under a raised deck dry and usable

How It Works
Our Helical Pier Installation Process
A helical pier foundation moves faster than a poured one, but it still follows a careful sequence to make sure every post lands on solid, load-tested ground.
- 1
Site Evaluation & Soil Assessment
We review your site plan, soil type, and local frost depth to determine pier length, blade size, and the number of piers your deck or pergola needs.
- 2
Pier Layout & Sizing
Post locations are marked to match your framing plan, whether that's steel deck framing, aluminum deck framing, or a traditional wood post layout.
- 3
Installation & Load Testing
Each pier is screwed to depth using hydraulic equipment and load tested on site, confirming it's rated to carry your deck or pergola before any framing begins.
- 4
Framing & Construction Handoff
With piers set and verified, your crew or ours can move straight into deck construction or pergola installation without waiting on concrete to cure.
