Spalling is cause of concrete pops; try a bonding agent in fix

Q. My concrete block foundation is 28 years old, and some of the brown solid color latex stain is flaking and peeling, both inside and out. I can handle that, but in a few blocks on the outside large chunks of concrete are popping off the blocks. Some are an inch deep, or nearly so. Would that be due to moisture? And does that mean that the blocks are filling with water? I tried filling the popped areas with mortar without success.
