Our company’s objective is to provide comprehensive concrete repair and restoration, using proven repair procedures, proper equipment, and the best repair materials for the job. No two structures deteriorate exactly the same way. The repair procedure for each is developed individually to restore structural integrity, our primary consideration.
Concrete spalling that affects structural integrity begins within the concrete at the reinforcing steel. Concrete’s high alkalinity causes a thin, invisible, protective oxide film to form on steel. However, when sodium chloride or calcium chloride are present, along with moisture and oxygen, carbonation occurs and the protective film is broken down and corrosion begins. As the corrosion builds and occupies more space inside the concrete, tremendous forces builds within the concrete. Cracking is seen first and if not properly repaired large sections of concrete begin to breakaway.
The International Concrete Repair Institute of which Con Tech is a member of, have issued guidelines for the proper long-term repair of the corrosion induced spalling. Proper repair of spalls includes precise surface prep, inspection and replacement of bad steel, use of a corrosion inhibiting bonding agent, placement of a high-early strength polymer modified repair mortars and proper curing.
