The sustainability concept is receiving significant attention as the need to address the nation’s infrastructure crisis becomes more publicized. The concrete repair industry is well-prepared with sustainable solutions as the need to reinvest in the nation’s infrastructure increases. This particular sector offers many ever-improving repair systems to restore the basic infrastructure essential for a high standard of living. It is therefore clear that concrete repair and restoration is one key solution to addressing the world’s aging infrastructure.
Tampa’s David L. Tippin Water Treatment Facility was built in 1924 to provide a dependable alternative to a scattered system of poor-quality wells. This American water landmark uses a process known as enhanced coagulation to produce up to 120 million gal. (454.3 million L) per day of potable water. This requires the use of aggressive chemicals (sulfuric acid and ferric sulfate), resulting in negative effects to the associated concrete structures. Because a reliable and safe water supply is essential to public health and safety, it is not an option to permit these structures to become inoperable due to concrete deterioration. A three-phase, $5.7 million project to address observed concrete deterioration commenced in 2004 and was completed in 2010. As a result, more than 600,000 persons spread over more than 200 square miles (518 square kilometers) will continue to benefit from a safe and uninterrupted water supply.
Not every repair project is a candidate for state-of-the-art concrete repair technologies; concrete repair technologies, however, will likely receive more appreciation and attention as public utilities seek sustainable solutions to the nation’s infrastructure crisis. The combination of effective diagnostics, the determination of the root cause of concrete deterioration, and the development of a cost-effective repair strategy resulted in a successful project delivery to the city of Tampa.
