Tieback anchors, sometimes called soil nails, are a structural element used to stabilize a structure. Tiebacks can be used to support an existing structure or as an added element for new construction. To install tiebacks, Ezra Construction drills a small shaft into soil, typically in a 15-45 degree angle. The tiebacks are then installed into these shafts after which we pressure pump the shafts full of grout.
The photo on the right is a shoring wall being installed with tieback anchors and shotcrete for the purpose of retaining soil of a San Francisco hill prior to the construction of a new garage.
