Understanding the Mystery of Helical Piles

When you look at a newly constructed building, you may see a magnificently built multi-story building that rises high above the earth. What you won’t see is the foundation that secures that building and keeps the structure in place, including piles. One of the most fascinating parts of modern foundation construction technology is the mysteries surrounding the helical piles. Here are a few facts about the piles you may not know.

Magic

The magic surrounding the way the piles work lies in their construction. Made from metal, the pile is a long, hollow shaft that supports the construction project once it is deep underground. To get the post where the workers need it, a large screw flange, or foundation screw, is attached to one end. As the pile is twisted, it will dig into the earth and bury itself deeper with each turn.

Support

Tall buildings require deep foundational support, but did you know that even one-story buildings or large homes that are sinking can benefit from helical piles? The piles, sometimes called piers or anchors, are pushed deep into the earth. That allows the enormous weight of any building or heavy construction to be evenly dispersed. For huge buildings, multiple piles can be used evenly to support the structure on a weighted platform.

Connections

As the corkscrew flange buries itself into the ground, the pile can be connected to segments that extend its length. Depending on the load requirements of the foundation, the pile may extend into the ground more than 100 feet and be up to 48 inches in diameter. To ensure the post is secure, concrete is poured down the hole to make sure there is no wobble that would allow foundational strain or weakening.

If you are considering a big commercial building project or want to construct a home in an area with weak soil, contact a helical piles company for more information. The foundation screws can prevent compromised stability of almost any building you choose to construct.
