We are putting a addition on in the spring and we do not have a ton of money, but i want it done right. I was told if we put a cement slab down instead of a foundation that it could shift. Is this a true story? I would like you to tell me how you feel about slabs vs. full foundations. Thankyou for all youre help. Debbie
Debbie, It all depends on where you live. I’m from the northeast and I hardly see slabs for foundations because of thr freeze/thaw cycle here. If your from the south where there is little chance for freeze/ thaw the slab will work fine. However if your from the north you must build a foundation with footings below the frost line. One advantage if your from the north and must build a foundation, you can build a crawl space and save about 1/3 fo the cost of a full foundation.
