This is what I have been told to do, so feel free to comment. I have an old house set up 10 feet in the air on partial pier, and -partial blockwall with slab- construction. The piers - when I look at them- appear to have a few rocks undernieth (still cant figure out my spellchecker) them and nothing else. In other words, I can put my hand easily under my piers in places and it would seem that some smallish lava rock is the only thing anchoring half of my house in place. This is not inspiring a lot of structural confidence for me. I was told to drill through the piers and put rebar through the holes and then pour a slab to hold the entire thing in place and also provide a floor for a lanai at the same time. The slab would be 3.5 inches thick in the center with a perimeter of about 6 or 8 inches around the piers. How do I specify this in a contract, and is it enough?
