Helical piles are ideal when challenging soil conditions prevent traditional foundations. Due to their performance, they can be used in nearly any project.

Using hydraulic rotary drive heads mounted on equipment ranging from hand-carried units to large excavators. A D&B project manager determines the most suitable equipment for each site.

Helical piles date back to circa 1720 in England. Lighthouses were supported by hand-installed helical piles in the 1800s.

We use a patented steel foundation underpinning bracket to permanently attach the pile.

Yes. The hydraulic jack and steel bracket system allows us to raise or lower a foundation and lock it permanently in place.

Not at all. D&B has on-staff engineers ready to assist. We can also provide the “Practical Design and Inspection Guide for Helical Piles and Tension Anchors” by John S. Pack, P.E.

Yes. We routinely install piles in crawl spaces, basements, and other tight quarters using hand-carried equipment with remote hydraulic power.

D&B maintains a fully stocked helical pile inventory, so we can meet your schedule without delays.

Depending on soil conditions and pile length, one crew can install 30–50 piles per day for new construction.

The pile transfers load through unstable soil to stable soil or bedrock. The lead helix bears the load, making it an “end-bearing pile.”

Helical piles are designed to last for over 75 to 100+ years.

Fast, clean, and cost-effective

Superior performance compared to deep or shallow foundations

Measured capacities verified during installation

Immediate load-bearing capability upon completion

D&B has been in business since 1968 and has been installing helical piles for the last 40 years.

There is no difference in this context; the terms are interchangeable.

Costs vary by project. Each job is evaluated individually, and detailed proposals are provided. Helical piles offer excellent value due to their performance and efficiency.
