Straight Line Construction and Ram Jack Companies have installed both cantilevered and tied back soldier pile and lagging earth retention systems throughout the Rocky Mountain region.

Soldier pile and lagging is a type of cantilevered earth retention system that utilizes vertical steel beams with wood or concrete lagging or panels between the beams to retain earth.
Soldier piles typically consist of W or HP steel sections and are installed in vertically excavated holes, typically drilled with an auger 12” to 36” in diameter. Depending on the permanency of the pile and lagging system, the drill hole around the vertical steel section will be backfilled with concrete, or a combination of concrete below the toe of excavation and flow fill above or in temporary applications, flow fill the entire steel element height. Soldier piles are often installed on 6’ to 8’ centers on the perimeter of a proposed excavation. After installation the inside face of the soldier pile is excavated and lagging is placed behind the front flange of the W or HP section to retain the earth between the vertical elements and transfer earth pressure to the vertical piles.
Soldier piles and lagging can be used in a variety of conditions. For very tall excavations where soldier beam size availability is not practical, the vertical elements can be supported by tieback anchors, which can increase the depth of excavations using a smaller vertical pile element. For zero lot line applications, rakers and interior bracing can be utilized for additional lateral support, keeping the vertical pile element economical.
Soldier piles and lagging can be used in a variety of applications including:
  • Temporary earth retention or shoring for excavations.
  • Permanent earth retention and shoring.
Some of the advantages of soldier piles and lagging include:
  • Can be installed in zero lot line situations.
  • Excavation proceeds uninterrupted for cantilevered soldier pile and lagging systems.
  • Tieback anchors can be utilized to reduce the soldier pile size and depth below the toe of the proposed excavation by providing additional lateral support.
  • Internal rakers and bracing can be used to economize the vertical pile section by providing additional lateral support.
  • Soldier beam and lagging can become permanent foundations for below grade structures.

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.
