Tie-back anchors are utilized to secure a shoring system. Tie-backs are drilled into soil or rock using a small diameter rod and casing, typically adjacent to a soldier pile, and usually installed at an angle of 25 to 45 degrees. Once the tie-back is drilled the hole is filled with grout and cables are installed in the hole. A tieback connection is welded to the pile and a tensile force is applied to the anchor. This tensile load supports the soldier piles during excavation.
