What Causes Concrete Cracks?

Before delving into repair methods, it’s essential to understand what causes concrete to crack in the first place. Concrete cracks can result from various factors, including:

  • Temperature Fluctuations: Extreme temperature changes can cause concrete to expand and contract, leading to cracks.
  • Excessive Weight: Heavy vehicles or objects placed on concrete surfaces can exert pressure, causing cracks over time.
  • Poor Installation: Improperly mixed concrete or inadequate curing can weaken the structure, making it prone to cracking.
  • Water Damage: Water infiltration due to inadequate drainage or leaks can erode the concrete from within, resulting in cracks.
