A slope failure in northwest Alabama has been stabilized using a system of grouted INSERT piles to provide load transfer across the failure surface of the slide. This system, referred to as a Type A wall, includes small diameter grout piles reinforced with a high strength steel pipe as well as permanent earth anchors. A program of instrumentation was installed in an attempt to both verify the performance of this system and measure the axial, shear, and bending forces in the key elements. This paper describes the INSERT wall repair of the slide as well as the plan and installation of the instrumentation. Initial measurements suggest that the majority of the instrumentation are providing reliable data and that the INSERT wall system has arrested the movement of the slide. The instrumentation is to be monitored over the next few years to verify long term success of the repair.
