This field is for validation purposes and should be left unchanged.
Helical piers, sometimes called helical piles, helical anchors, or screw piles are deep foundation elements that generally consist of a steel shaft with single or multiple helical bearing plates on the lead section and various length extensions. A wide variety of connection hardware is available for helical piers. Standard new construction brackets with bearing plates are commonly used for new foundations to transfer loads from the foundation to the pier. Steel Guide Sleeve and underpinning brackets are also used for remedial applications to transfer loads from existing foundations and to provide additional foundation support.
Helical piers are installed with hydraulic torque heads. The torque heads may be mounted on a variety of equipment including excavators, skid loaders, mini-excavators, hand carts, or custom man-portable frames designed to operate in very limited access conditions. The lead section of the pier with the helical bearing plates is attached to the torque head and the pier is advanced by rotating the pier with the torque head while applying downward pressure (crowd). Once the lead section is advanced, additional shaft extensions are attached (either bolt together or screw together piers are available) and the pier is advanced until the required installation torque is achieved. The pier top is then cut off to the desired elevation and the appropriate mounting hardware is attached.
Helical piers can be used for new construction applications or for remedial repair work where settlement and damage has occurred. Helical piers can also be used to provide additional capacity when required for seismic retrofits or remodels. Typical allowable capacities for new construction helical piers range from about 15 to 100 kips (30 to 200 kips ultimate with a Factor of Safety of 2). Larger sizes and higher capacities are also available. Helical piers provide positive load transfer from new or existing foundations to suitable bearing strata. Helical piers are particularly well suited in areas where softer or looser soils overlie a stiffer or denser bearing layer. Battered helical piers can be used to provide additional lateral support where needed. Hydraulic jacks can also be used in conjunction with underpinning brackets to raise existing foundations in remedial applications after the piers have been installed.
Helical piers can be utilized in a variety of applications including:
  • Construction of new foundations where softer soils are present near foundation bearing elevations or where additional load capacity is desired
  • Remedial repairs of existing foundations
  • To raise foundations that have settled
  • As tie-backs to provide lateral resistance for retaining walls
Some of the advantages of helical piers include:
  • Relatively economical compared to many deep foundation systems.
  • Fast installation.
  • No drill spoils are created, this is particularly beneficial where contaminated soil is present.
  • All elements of the helical piers are made from steel, there is no need to wait for concrete to cure before loading the piers.

About Ram Jack

Ram Jack is a family-owned business that began operations in 1968, in Ada, OK, where we currently source our piers and brackets. Back then, concrete piering was the original repair method used simply because it was the only technology available at the time. Over time, it became evident that concrete piers did not provide long-term stabilization of foundations and only provided a short-term warranty period. To guarantee the highest grade of customer satisfaction, a greater solution needed to be found.

The Ram Jack owners embarked on a research program to develop a foundation repair system to stand the test of time. The U.S. Patent and Trademark Office first issued a patent to Ram Jack for its foundation repair system in 1985. Over the next few years, additional refinements and patents have followed, resulting in the strongest patented system in the industry. Ram Jack driven pilings are ICC-ES recognized (International Construction Code—Evaluation Services). Ram Jack is one of only two ICC-ES recognized foundation repair companies in the industry. Ram Jack’s products meet or exceed code requirements set down by ICC-ES for both commercial and residential properties.
