You have several options when your wall deflection reaches beyond 2-inches. Your first option is to excavate the soil that is exerting pressure on your basement wall, and to push the wall back. Another option is to install a steel mechanical system such as steel tie-backs. We recommend reinforcing the wall with carbon fiber regardless of which system is chosen to prevent future inward movement. Please contact your structural engineer or foundation repair specialist to do a thorough inspection and analysis.
