One year old home on Warranty Inspection.
Observed, and homeowner commented on, this pockmarked concrete present on the sidewalk and driveway.
The voids shown in the picture were numerous over the surface of the concrete. If you look at the pictures you can see the progression of the problem. They start as the crack, then progress into a hole. (progression pictures are from right to left) The sizes varied.
Apparently the homeowner’s neighbor has already had an inspection and the builder has agreed to replace the driveway and sidewalk ( a rarity around here in my experience.)
My question is, What is the problem called? What causes it? How would you write it up?
