A roadway was need that would cut through a hill in such a way that load bearing soils for existing apartments would be put at risk for movement. This Ideal Dealer was able to provide the answer. A 300’ long wall, 28’ high was installed in approximate 7’ cuts using 130 Helical Tie-back Anchors with 6” of Shot-crete over a 12” x 12” grid of #5 rebar. The 2 7/8” Helical Tie-backs provided a 40 KIP working load at 30’ deep. The engineers on that project were still talking about it years later and they have developed quite a working relationship with this Ideal Dealer.
Near Grade the soils were loose so flake board was used to hold it in place. This provided a challenge since the Shot-crete wouldn’t stick to the flake board. The answer was temporary underpinning on that section of the wall until it dried.

A helical pier is a deep foundation. Its purpose is to transfer a structural load to deeper, stronger, and less compressible materials bypassing any weaker and more compressible materials that would be unsuitable for the support of a conventional shallow foundation.
As a deep foundation, a helical pier should be considered for most applications that would call for a driven pile, drilled pier, or mini pile.
Helical piles and anchors are usually a great foundation solution to any of the applications below whether it's a new build or existing structure.

A typical helical unit is shown here. This unit consists of a central steel shaft or lead section, to which can be attached one or more steel helices (helix). The central shaft can be lengthened by adding extension pieces as necessary.
These extension pieces are connected using the bolted coupling. Pipe shafts are seldom less than about 3 inches in diameter. If necessary, shafts greater than 12 inches in diameter are used.
The final component to the helical unit is the Load Transfer Device (LTD). This unit transfers the tension or compression load from the structure to the helical unit. New Construction LTD and LTD for underpinning are two of the many LTD’s available.
