<br />CONCRETE CRACK MAINTENANCE
<br />Cracking occurs in concrete structures due to inherent shrinkage, creep' and the restraining effects of
<br />walls and other structural elements. Most cracking due to shrinkage and creep will likely occur over the
<br />first two years of the life of the structure; further concrete movement due to variations in temperature
<br />may persist. Cracks that result inwater penetration will need to be repaired to protect reinforcing.
<br />Other cracking may be repaired at the owner's discretion for aesthetical reasons or performance of
<br />applied finishes. Prior to repairing cracks, a structural engineer should be consulted to provide direction
<br />on which cracks to repair and on whether observed cracks may affect the strength of the structure.
