The most expensive concrete repair is the one that has to be done over. One of the most common causes of pavement repair failure is incorrectly determining patch size. Full-depth patches should be large enough to provide a smooth transition for traffic. Partial-depth patches are most likely to fail if not enough deteriorated concrete is removed to expose sound concrete. Other areas of concern are:
  • patch dimensions
  • subbase repair
  • dowel bar alignment and placement
  • smoothness specification
  • sealing joints
  • removal of old concrete
  • compressible inserts
  • bonding grout
  • finishing and curing.
