Negative-side sealing attempts to coat the inside wall of the basement with a 'waterproof' paint, coating, or sealant. This solution will generally work very well for about six months to two years (check the warranty), and then the product will begin to respond to hydrostatic pressure and will blister and peel, soon spalling from the wall completely.
