This document summarizes restoration materials and technologies from ConSpec including Ambex, Cintec, Helifix, Ruredil, and VoidSpan. The technologies are for anchoring, strengthening, and stabilizing masonry and concrete structures. They include cement anchoring capsules, wall ties, structural strengthening systems, fiber reinforced cement matrix systems, and systems for filling voids. Many of the technologies have been used successfully for over 10 years and can help reduce costs, risks, and construction time for restoration projects.
