Concrete Repair and Restoration
Concrete Repair is a key component of many structural stabilization, restoration and strengthening projects. Over time, the repair of concrete structures becomes a necessity as deterioration of the embedded reinforcing results in cracking and spalling of the concrete elements. If left un-abated, failure will eventually result.
The prime factors in concrete deterioration are air and moisture which result in carbonation of the concrete. In colder climates the use of salt, as a deicer, results in chloride attack of the reinforcing. Both carbonation and the presence of chlorides destroy the natural alkalinity of the concrete resulting in corrosion and subsequent expansion of the embedded reinforcing.
