Delta MS, Shell Busey... is Shell a waterprooing expert or gas station, got milk?

“Waterproofing–CHECK”, with Johny Bubb’s

Mr Shell, if Delta or any dimpled membrane is sooooo great then why do we see leaky basements where the builder or contractor used this stuff? lol

Seems many just repeat the claims made by the manufacturers instead of trying it out over an extended period of time n maybe ask those who do this kind of work, eh.
