You have it wrong bro

6:35 he shows the black gooey stuff, he says it is DAMPROOFING and says, moisture and concrete don’t go well together and claims, damproofing prevents any moisture from the soil to get into the foundation… and says all that crap soil will be backfilled against the thin, weak, sorry damproofing lol

9:00 shows gravel, lol ya sure you can afford all that?

9:25 he says sump pump connected to main city tie in lol, city pump stations love this shtt n so do all homeowners who get back ups
