You should better hire a licensed concrete or sidewalk repair contractor in Brooklyn to make your property enduring and long-lasting. The cause of tension and resulting cracks could be due to:

  • Rusting of reinforcing steel due to one factor or the other causes expansion, thus creating tension and resulting cracks and pops offs.

  • Another hidden factor could be the alkali-aggregate reaction (AAR), which forms a gel around aggregate particles. If the gel comes in contact with water, it expands and makes the concrete weaker. You can ask Brooklyn, NYC concrete crack repair contractor to suggest lithium products to mitigate the AAR.  
  • On the structural side, one of the factors could be the drying shrinkage, caused mainly due to high moisture and restrained natural shrinkage. Joints could be of great help in controlling drying shrinkage cracks.
  • If the concrete surface is allowed to dry out before concrete gains strength, a pattern of cracks could form on the surface. These cracks, although sallow and narrow, could be a problem in the long run.
  • If concrete surface finishing and sealing in done prematurely, this could cause blisters. In the long run, these could develop in cracks.
