Can someone please tell me why slab on footing isn't done in Thailand - at least what I've seen? I don't know how to post a pic but I'll try. This is done all in one pour. and note that the footing on the right is for an interior load bearing wall. It could also be just the equivalent of a post if a load was going to be on a post. It would probably be about -1 meter square if for just a load bearing post.
Also, do people use 6 mil plastic under the slab to keep moisture from wicking up from the soil? This save a lot on aircon and also on mold problems.
Footings can be as deep as needed.
Anyone?
