can this be used on concrete roofs where the rain water is channeled to a storage cistern for drinking water?

Yes, RadonSeal can be used for this application. No problem. There is no concern about leaching or water contamination.

How well does this work for seepage between the floor and foundation wall?

Very well. Used it once on walls and floor never saw any wetness after that?

Can this be used over painted basement walls

RadonSeal is a penetrating sealer. This type of product can only be applied to bare & porous surfaces. All paints, previously applied sealers, and other materials that may prevent sealer penetration should be completely removed before treatment.

Can this product eat away at a basement concrete floor causing solf spots, chipping and cracking. is it possible if over used that it may destroy the

Not at all. My floor and walls are stronger then ever. It purges out dirt and loose dust when first applied but stengthens the concrete after it cures.I think the curing process takes a couple of days to a week. I just swept and washed the dirt away
