I would look at putting XYPEX in the concrete to make the concrete
waterproof (it makes a crystal structure in the concrete that is
waterproof - it is available at whitecap) and call out a higher
strength concrete mix to get the concrete closer to waterproof like 4000
psi - but look at the XYPEX.com - it seems then you will be making a
tank -not a basement
