Helical piers are used in foundation repair — if you are experiencing sagging foundation or cracked drywall, for example — whenever there is a need to resist a tension, a compressive force, or both. Helical anchors look like a large screw. They are ideal for foundation repair applications including support for settling porches, steps, stairs, chimneys, and so much more. They can be used in commercial, residential, or industrial foundation repair applications.
There are many cases in which the helical pier or helical anchor have been considered the best solution for a foundation project.
Helical piers are sometimes referred to as ground anchors or screw anchors. Here are some of the many applications where helical piering systems have been used:
Helical piers have been used for over 150 years to provide deep foundation support for supporting structures built on weak or wet soil. For example, coastal and wharf-related structures like lighthouses and bridges have often required helical piers to provide a strong foundation.
When the hydraulic motor became available in the 1960’s, helical piers became even more widely used because the motor allowed an even faster, safer installation process for the piers. Both commercial and municipal groups find helical piers very useful for pipeline and pumping equipment support, elevated walkways, retaining walls, bridges, and many uses in the electric utility industry, as well.
The helical piering system from ECP consists of a shaft that is fabricated from solid steel or tubular steel. Helical plates will be welded to the shaft. These plates can range in diameter from 6 to 16 inches depending on the application. The plate diameters increase from the bottom of the shaft upward. They come in shaft lengths from 10 inches all the way up to 120 inches, but other lengths can sometimes be fabricated if the application dictates the need.
Helical plates may also be installed on an extension where the length of the lead is not enough to allow for the right intervals between the plates. Helical piers may end with a pier cap embedded into a concrete foundation. Foundation brackets are available that attach the pier or anchor to the foundation beam or footing.
