What is the best way to build a slab foundation on a slope?
The grade on the building site drops 8 feet over 72 feet. Is it feasible and cost effective to build three slab foundations that step down in order to deal with the slope. The top foundation would be a for a single story 15 by 24 room. The next level would be a 24 by 24 two story structure and the garage would be at the bottom leve. I assume that this would require retaing walls from each higher slab to the one below. Thanks, Keri
