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.
