Concrete is made up of water, aggregate and cement with a variety of additives designed to achieve the specific physical properties for the specific need or application. Steel reinforcement is a major component of concrete construction especially when structural requirements are present.
Over time, concrete can degrade, the causes are various and range from chemical damage, fire damage, corrosion of embedded steel reinforcements, physical damage and aggregate expansion.
Ev-Air-Tight, Shoemaker has extensive experience repairing and strengthening concrete structures. The first step is to determine the cause of degradation and then by selecting the appropriate technique Ev-Air can restore the concrete structure to its original condition. Strengthening techniques include increasing the overall cross-section of the existing structure, the addition of external reinforcing members such as steel plates, beams and columns or the addition of fiber composites.
