We find that it is very common to see garage approaches settle. This can be due to poor backfill and compaction. Many times, however, the problem is either caused, or at least aggravated, by improper drainage. So often we see downspouts that do not get rainwater far enough away from the home. Downspouts that dump water near the corner of where the garage and driveway meet can result in the sub-base being washed away. When this happens, voids develop and the concrete can settle and/or crack.
