It is in the area of repair and rehabilitation of existing structures that CA’s discriminating and innovative approach to problem solving excels the most. Today’s dwindling economic resources combined with increased user demands pose formidable challenges to owners, investors, developers, and governmental agencies to better utilize existing resources. CA has established a leadership position in the application of the latest state-of-the-art technologies, materials, and equipment for the repair and rehabilitation of existing facilities. CA has been responsible for repairing structures such as parking structures, precast panels, prestressed beams, post-tensioned slabs, foundations, pavements, marine piers, industrial floors, commercial and residential construction, bridge decks, grain silos, and buildings, among others. CA has played a leading role in the implementation of the use of composites, such as fiberglass and carbon fiber in the repair and strengthening of structural members. Projects involving structural rehabilitation using fiber wrap technology for structural elements have been achieved at a fraction of the time required to achieve similar results using traditional strengthening techniques. CA has also been involved in the use and implementation of innovative polymer materials for the repair of cracks, restoration of structural integrity, and remediation of concrete surfaces. These materials have significant advantages over traditional polymers, such as epoxies, given that their application requires no injection since these materials travel where moisture travels, thus ensuring their effectiveness, restoring functionality, and improving durability.
