Helical Pier Systems' tie-back anchors are used for slope restoration / stabilization. Once the fault line has been found, anchors can be screwed in almost horizontally into more stable soil. Following installation, an appropriate retaining wall is attached, which helps maintain the slope integrity. Every wall tieback situation is unique. The placement of the anchor is influenced by the height of the soil backfill against the wall. This image, shows this condition and a guideline for setting the location of the tieback anchor. Experience dictates that the tieback should be located close to the point of maximum wall bulge and/or close to the most severe transverse crack. The tieback placement location must be selected on a case-by-case basis.
