I agree... With 8"s thick it will hold pretty well... What condition was the ground in when you poured the slab ? Did you pour over solid ground that had never really been disturbed ? Was the top soil skimmed off and gravel put down, if so was it compacted really well ? I would want the ground to be good and solid under the slab if i was going to attach the walls to the slab... How long has the slab been there ? A good way to get an idea of how good the ground is under the slab is looking at how many cracks you have ib your floor... The less cracks the better... Also i would brace the heck out of the walls and corners like you were building in a Huricane area...

Yea digging footers and putting in a foundation wall would be pricey, mainly because concrete is so dam expensive these days...
