Anybody done it ?
Can it be done? Yep.
Would I do it myself? Yep. (but I know what I'm doing)
Is that your best option? Don't know without more info.
There are LOTS of variables here.
How many cubic yards of dirt will it take? Size of the pad (not just the slab, add at least a few feet on each side - more for slopes) multiplied by the average rise desired, divided by 27. (cubic feet in one yard) Example: The slab will measure 40'x50', so you want the pad to be 60'x70'. You decide that the pad needs to be 6" above natural ground at the highest corner. Shooting the grade, you determine that the fall from the highest point to the lowest point is 18". That would give you an average rise, for the entire pad, of 1' So, 60 x 70 x 1 = 4200 cubic feet. Divided by 27, that's 156 cubic yards. Add about 10% for shrinkage, and you're looking at 166. I'll be generous and say that you can carry 1/4 yard per bucket load. That's about 664 trips. How far away is your source for the dirt?
Also, don't forget to add enough fill dirt to replace the topsoil/grass that you remove before starting the pad.
Can you get sufficient compaction with the dirt available? If not, the money you saved by doing the pad yourself, won't be anything compared to the cost of repairing a cracked slab. Note: never add more than a 6" lift at a time. Even with heavy equipment, like a sheep's foot roller, you can't pack more than 6" at a time. With a small tractor, you would probably need to add no more than 2-3" at a time.
If you have no idea what I'm talking about (above), hire a professional. Think about it: What are you going to spend on the house? $100K? Maybe $200K or more? And, you're wanting to save a few hundred bucks on the foundation? I'm not picking on you. Just trying to give a thoughtful, honest answer to your question. If you really know what you're doing, then ignore this reply and mark it off as the rant of an old lunatic.I wish you the best, and I try to encourage people to do things for themselves. But, a house foundation is one place that you really need to know your stuff, or it could cause serious problems.
You are very wise...excellent advise.
