when i built my basement in the last century (1996), i coated the concrete with 2 layers of a product called thouroughseal...i think thats what its called. a grey coat then a white coat to make sure i had 2 coats. then a 1/4" layer of Bituthene over a primer. thats a self sealing product. then installed a layer of 1-1/2" insulation board to protect membrane. I have never had any leaks.
also installed a perc pipe system.
