Cracks in concrete, whether in buildings, roads, structures or bridges, indicate damage and should be closely and accurately monitored to assure the integrity, safety and underlying durability of the structure.

These cracks can form for a number of reasons:

Sub-par construction practices,
Chemical reactions causing corrosion,
Repeated freezing and thawing,
Construction overloading,
Or any combination of the above.
Depending on where the crack is located, the issue may be superficial or an indication of damage of a larger scale. The significance of the damage depends on the location and size of the crack, and how they can ultimately affect the structure’s safety and durability. Monitoring of the cracks is essential in evaluating what maintenance actions will be needed for the affected area based on the severity of the damage.
