The first step when waterproofing your own basement is finding the source of the water leak. Most leaky basements have water entering the home where the floor and walls meet. This is commonly called the cove joint. A basement that leaks water through the cove joint can be remedied with our do-it-yourself SealOnce Basement System. The hollow baseboard collects the seeping water from the cove joint and and seepage from the face of the walls and direct it into the channel and carries it around the perimeter of the basement to the drain outlet.
