Helical Piers & Anchors

Helical piers, anchors, and brackets are used in foundation repair whenever there is a need to resist a tension, a compressive force, or both.

Helical anchors look like a very large screw, and 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. From adding support for a leaning chimney to utility and civil construction projects, these foundation piers are some of the most widely used foundation repair tools available today.

Advantages of Helical Piering Systems

There are many cases in which the helical pier or helical anchor have been considered the best solution for a foundation project.

  • Permanent solution that keeps your home stabilized
  • Easy installation procedure
  • Minimal vibration causes little disturbance to your yard
  • Each pier is load tested before use
  • Can be installed in any type of weather
  • The installed torque correlates with the capacity
  • The load of the structure can immediately be transferred after installation

Where Are Helical Piers Used?

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:

  • Tiebacks
  • New Construction
  • Foundation Repair
  • Guy Anchors
  • Shoring
  • Tilt Walls
  • Soil Nails
  • Slab Repair

Helical piers have been used for over 150 years for supporting structures built on weak or wet soil. When the hydraulic motor became available sometime in the 1960’s, helical piers became even more widely usedbecause 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.

Our Process

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.

Earth Contact Products and My Foundation Repairs both
recommend that only a registered engineer oversee the design and application of helical piers / anchors when used in foundation repair or new construction projects. As you can see, the helical piers used are very specific to the job, and specialized equipment is needed for the installation.

If you notice signs of foundation problems such as cracks in walls, ceilings, floors, or slabs, or you notice doors that stick, chimneys that lean, or sloping and uneven floors, you should not prolong repairs. Contact My Foundation Repairs today and let us find a foundation specialist in your area to see if helical piers are the right foundation repair solution for you.
