I am having a manufactured home put up in North Texas, in the middle of a drought.
My site is on the side of a hill, and the mobile home retailer contracted some guys to dig out the the hill and use that dirt to level a spot for the home. On one end of the pad, the non-native soil is about 18"-24" deep. On the other end, almost solid rock.
All they did to pack the soil was to drive over it with a small dozer.
I have no experience in this and asked several people if this will work, most said it is a bad idea.
So on the suggestion on many, I decided to go pier and beam. All the pier and beam guys I called will only go down to 18" piers max.
My questions is, if you put 18" piers in soil that isn't packed that good, am I getting any benefit from the piers, or am I still gonna have alot of problems?
