When you’re building a new home in Teton Valley, Idaho, or Alta, Wyoming, your foundation is more than concrete in the ground — it’s the single most important structural choice you’ll make. Here, the climate is extreme, the soil is unpredictable, and the stakes are high. You’re not just building a house; you’re creating a legacy property meant to last for generations.
That’s why more architects, engineers, and homeowners in the Tetons are starting with helical piers — and calling ParkFab, the local certified expert, to install and test them from day one.
Helical Piers 101: What They Are and How They Work
A helical pier is a steel shaft with one or more spiral-shaped plates (helices) welded to it. These are hydraulically screwed into the ground until they reach a predetermined torque reading that directly correlates to load-bearing capacity.
Unlike traditional footings, where capacity is assumed based on a soil report or a neighbor’s excavation, helical piers prove their strength during installation.
Key advantages:
-
Measured capacity: Torque readings confirm every pier’s load support in real time.
-
Depth on demand: Each pier is advanced to competent soil — even if one pier hits bearing at 8 feet and the next at 18.
-
Immediate use: No curing time; construction can begin right away.
Why the “Test and Measure” Method Matters Here
The Tetons are not forgiving to guesswork.
-
Variable soils: Within a single lot, you can find silty loess, clay, sand, gravel, and fill — each with different bearing strengths.
-
Seasonal extremes: Our climate swings from –40°F in winter to 90°F in summer, with deep frost lines and aggressive freeze–thaw cycles.
-
High snow loads: Roofs and decks here often carry more than 100 pounds per square foot in peak winter.
Without testing, you risk either overbuilding (and overspending) or underbuilding (and compromising long-term stability). ParkFab solves that by installing test piers before finalizing foundation design, so you know exactly what you’re building on.
Why Start With Helical Piers for New Builds
Too many people think of helical piers only as a repair tool — a fix for foundations already in trouble. But for new construction in Teton Valley and Alta WY, they can be the smartest first step:
-
Avoid Over-Excavation
No need to dig out massive volumes of unsuitable soil and backfill with engineered material. Helicals bypass weak layers and anchor directly into stable ground. -
Keep Your Schedule Moving
Install any time of year — even mid-winter — without waiting for concrete to cure. -
Perfect for Complex Architecture
Large-span living rooms, cantilevers, pools, outdoor kitchens, snow-loaded decks — helicals can support heavy point loads with precision. -
Future-Proof Stability
By measuring and logging every pier’s capacity, you get a documented foundation performance record from day one.
Where Helical Piers Shine in the Tetons
Wetlands & High Water Table Lots
Helicals bypass moisture-sensitive soils and seasonal swelling, locking into deep stable strata.
Mountain Benches & Slopes
Mixed rock and soil profiles are no problem — torque monitoring ensures every pier reaches design capacity.
Subdivisions on Fill
Avoid relying on non-structural backfill; helicals find native bearing soil regardless of surface conditions.
Architecturally Ambitious Builds
Heavy timber beams, structural steel, and oversized decks need precision support — helicals deliver it.
How ParkFab Installs Helical Piers
Shawn at ParkFab specializes in foundation systems for high-performance homes in the Tetons. His process:
1. Site Review & Coordination
Works with your engineer/architect to determine pier layout, load requirements, and bracket/cap types.
2. Test Pier Installation
Drives one or more test piers to confirm real depth and torque before committing to full installation.
3. Full Installation
Hydraulically advances each pier to target torque, recording depth and capacity for every single pier.
4. Integration with Foundation System
Attaches grade beams, structural steel, or timber posts directly to the piers — ready for framing immediately.
The Climate Factor: –40 to 90
Our extreme temperature swings create repeated expansion and contraction in shallow soils. In a traditional footing, that means movement, cracking, and seasonal shifts.
Helical piers bypass the active frost zone entirely, anchoring in soil that doesn’t change with temperature. That’s why they’re used in arctic installations, high mountain regions, and — increasingly — in Teton Valley and Alta WY luxury builds.
Cost, Value & Long-Term Payoff
While helicals may cost more than shallow footings on paper, the real value comes from:
-
Eliminating over-excavation costs.
-
Preventing change orders when poor soils are discovered.
-
Avoiding delays due to weather and curing times.
-
Preserving landscaping and minimizing site disturbance.
-
Protecting long-term resale value with a foundation performance record.
For a multimillion-dollar build, the upfront investment in torque-verified stability is minimal compared to the cost of repairs later.

FAQs
Q: Can helical piers be installed in winter?
Yes. Snow, frost, and freezing temperatures aren’t an issue — piers bypass frozen layers to reach stable ground.
Q: How deep do piers go here?
It varies by lot — anywhere from 8 to 20+ feet, depending on when torque readings hit target capacity.
Q: How long do they last?
With proper coatings and materials specified for soil conditions, helicals can last 75+ years.
Q: Do I need an engineer?
Yes. ParkFab works directly with your engineer to design the pier layout and load requirements.
The Bottom Line
In Teton Valley and Alta WY, building a home that lasts starts with knowing — not guessing — what’s under your foundation. Helical piers give you that certainty from the first day of construction.
With torque-tested installation, proven load capacity, and a documented performance record, you’re not just building for today — you’re building for decades of Tetons winters and summers to come.
