Helical Piers for Unstable Soil
in Helena, MT
If you’ve ever tried to build on Helena soil, you know how tricky it can be. Between the moisture, freeze-thaw cycles, and soft ground across parts of the valley, standard concrete foundations often struggle to stay stable. That’s where helical piers come in.
At Dalbec Construction, we use them to create a solid base that stays put—no matter what the soil’s doing underneath..
Why Unstable Soils Cause So Many Problems
When the ground moves, your foundation moves too. That’s how you end up with cracks in walls, sticking doors, and uneven floors. Many Helena properties sit on soil that expands when it’s wet and contracts when it dries. It’s not bad soil—it’s just unpredictable and a bit trickier to build on.
Helical piers work differently. They reach down to firm, steady layers below the surface, so your structure rests on something that doesn’t shift with the weather.
Built for Montana Conditions
Helical pier installation – We specialize in helical pier installation for underpinning deep foundations in residential and commercial concrete construction prior to pouring the foundation work, basements, and crawl spaces, etc.
After more than 25 years working across Montana, we know every project starts with one question: what’s the ground like?
Our pier systems are designed for the unique mix of clay, moisture, and cold that defines this region. Whether it’s a new home, shop, or foundation repair, we customize each pier setup to match the soil conditions and load requirements of the site.
What We Handle
- New foundation pier installations
- Support for crawl spaces and basements
- Pier systems instead of sonotubes
- Deep foundation solutions for wet or unstable sites
If you’re not sure which option fits your project, we’ll walk the site with you, explain your choices, and make sure the foundation plan makes sense before anything goes in the ground.
