This document summarizes restoration materials and techniques from several companies for anchoring, strengthening, and stabilizing structures. It discusses approaches that are minimally invasive and reversible such as stress reduction through increased bearing area. Various cement and epoxy-based anchoring systems, strengthening fabrics, and concrete repair materials are described. The document emphasizes that many of these technologies have been used for 15-30 years and have a proven track record in restoring historic and other structures.
