We are currently looking at building a home with a slab foundation. The lot location is in a low lying area which has in the past been heavily saturated with water. The sudivision was developed recently with a lot of grading and earth moving being completed to raise the lot elevation and also to put a drainage ditch behind the lot to prevent flooding. I have been assured the lots have been compacted to stabilize the ground but I am uncertain if this will prevent any significant settling in the future if I build there. The Builders use slab foundations and I believe they are using some form of cable tension / expansion slab installation method. I have inquired about if they would have any piers or footings in this foundation and they said it is not currently engineered for that kind of slab foundation but if I wanted a pier foundation they would do it for $$$. My question is what is the different methods for pouring slab foundations and considering my description of the lot, which method would you recommend to minimize foundation settling and problems in the future?
