How deep down can Helical Piers Be DrilleD

Helical piers are very useful tools in construction for many reasons, and you’ll often see them supporting the foundations of many different structures. However, using these piers in your designs requires knowledge and planning. To help you understand, here’s a look at how deep you can drill helical piers.​

The Depth
While the exact manufacturing differs depending on the depth necessary for the construction site, the general limit for these helical piers is 100 feet. That isn’t to say your helical pier needs to be 100 feet deep you can get much shorter piers for your designs. Likewise, you can order the piers to meet the depth you need so they fit your site’s specific requirements.

Why It Matters
The reason why the depth of the helical piers matter is because they’re useful for stabilizing foundations. Most large structures need a good foundation to stay in place, but this can be very problematic in places where the ground is loose or wet. Helical pier manufacturers make helical piers that can drill past loose soil and find purchase deep in the ground. This helps stabilize the foundation and keeps the building safe.

Places Where Helical Piers Are Useful
Both commercial and residential buildings can and do use helical piers it all depends on the building’s location. Places with unstable soil—especially permafrost soil—are prime candidates for helical piers. Helical piers are also very common on beaches or waterfronts with structures like piers and docks that stand atop sandy ground. Knowing how deep your helical piers can go is important because the structures using them are so different.

As long as you understand these few principles about helical piers, you can better plan your structures in unstable locations. Helical piers are powerful tools for creating good foundations and buildings wherever you need.
