The wall anchor system is a property owner’s alternative to completely removing and rebuilding foundation walls that have become cracked and bowed as a result of lateral earth pressures exceeding the allowable design capacity of the wall.
The Grip-Tite® Wall Anchor System consists of an interior wall plate, an exterior earth anchor and a connecting steel rod to stabilize foundation walls by counteracting the pressure being exerted against the wall. The system is utilized to anchor foundation walls and exterior earth retaining walls constructed of masonry block or cast-in-place concrete.
The U.S. Department of Housing and Urban Development (HUD) recognized wall anchors as a viable option for stabilizing basement/foundation walls. An April 24, 1992 HUD memorandum states, “There are three common ways to save bowing foundation walls:
- Contractors install wall anchors on approximate 6’ centers. These stop further movement and with proper tension will eliminate some, if not all, of the bowing over time.
- Another acceptable, but more expensive method, is to replace the affected walls.
- The third is to use passive resistance such as grout filled channel steel or pilasters which may stop further movement. This is the least effective.”
The GRIP-TITE® Wall Anchor System has been evaluated for compliance with all applicable building codes by building officials of the International Code Council (see ICC-ES Legacy Report #22-03).
