Tie-Back Anchors: Injection Bore Anchors

August 21st, 2015 by

VersaGrade installs both helical tie-back anchors as well as injection bore (IBO) anchors. The injection bore anchors use the same process and materials used for soil nails and micropiles, but anchors are typically installed deeper into suitable soils on an angle. The grout-encased hollow bar transfers tensile loads to the surrounding soils and relies on soil resistance to prevent the tie-backs from pulling out and destabilizing the wall.
