Helical Anchors
In 1988 RJG Construction, Inc. realized that an alternate method of underpinning would be needed due to the extreme expense of conventional steel and concrete methods. It was soon determined that helical piles, which had long been used by the utility industry as a method of guying power lines and transmission towers would be the perfect alternative as an underpinning method. Helical anchors are a pre-engineered system and are designed for tension and compression application, under some circumstances lateral loading can also be designed into a helical pile system.
Over the past 25+ years helical piles have become a preferred method of underpinning which has resulted in a vast increase in contractors now exploring the attributes of this system. RJG has installed helical anchors manufactured by every major provider over the past 25 years, however we rely upon anchors provided by Earth Contact Products (ECP) , to fill our underpinning, tie-back, and soil nailing needs. ECP offers both square and round shaft anchors listed in their ICC-ES evaluation report # 3559.
Don't be fooled by those installing material which is "manufactured to ICC standards" if the contractor cannot provide a current ICC evaluation report.
