Retaining wall repair required soil nails, helical piles, block repair and carbon fiber strengthening

The repair on this retaining wall, on a school campus in the West Valley, required several of our innovative technologies and the expertise of our team to provide design assistance to the engineer and then to complete the engineered repair design.

The damage to the wall was due to both horizontal and vertical movement. To address the horizontal movement we installed (7) Titan hollow bar grout injected soils to a depth of 30 feet. The soil nails terminations were covered with a metal cap for aesthetics and to protect people walking by from injuries. The vertical movement was stabilized with the installation of Helical Piles to a depth of 20 feet. Once the wall was stabilized, the repair to the cracked and broken block could be completed. The cracks were injected with epoxy and the voids were repaired using a high strength polymer-modified repair mortar. To provide additional strength the wall was then wrapped with a bi-directional carbon fiber fabric.
