Our home rests on top of concrete blocks which, in turn, rest on top of 24" X 24" X 2" pads. The pads sit on top of the dirt. We want to replace the blocks with properly designed spot footings. That part I can figure out. There are plenty of references for how to design a spot footing. The problem is, I need to be able to create the spot footings one at a time, over a long period of time, until they are all finished. My question is this: If I create spot footings, can I come back later and "fill" in between them (around the outside of the house) with a continuous wall of concrete blocks? When finished, it would basically be a continuous spread stem wall made of concrete blocks -- capable of supporting a second story addition. Good idea? Bad idea? Overkill?

HI, my concrete veranda is all pitted (age and use of salt in winter). I was wondering what the best prep products were to refinish the top of it were - a sealer or a new layer of concrete? And has anyone worked with slate for walkways - is it better than concrete?
