Causes of Concrete Cracking

Concrete can crack due to various factors, and epoxy resin can be used to repair many types of concrete cracks.

Common Causes of Concrete Cracking

Here are some common causes of concrete cracking and how epoxy resin can be used for repair:

  • Shrinkage
    Concrete undergoes shrinkage as it cures and dries, which can result in cracks known as "shrinkage cracks." These cracks are typically small and occur as the concrete contracts.
  • Temperature Changes
    Fluctuations in temperature can cause concrete to expand and contract, leading to thermal cracks. These cracks are more common in areas with extreme temperature variations.
  • Structural Overload
    Excessive loads, whether from heavy equipment, vehicles, or structural stress, can cause concrete to crack if it exceeds its load-bearing capacity.
  • Settlement
    Uneven settlement of the ground beneath a concrete slab can lead to cracking as one part of the concrete sinks or shifts relative to another.
  • Chemical Reactions
    Exposure to chemicals, such as those found in de-icing salts, acids, or alkalis, can deteriorate the concrete surface and contribute to cracking.
  • Corrosion of Reinforcing Steel
    When steel reinforcement within the concrete corrodes, it can expand and cause cracks known as "corrosion-induced cracks."
  • Inadequate Construction Practices
    Poor concrete mix design, insufficient curing, improper compaction, and other construction-related factors can lead to cracks in the concrete.
