"Foolproof" Basement Drainage System

"Foolproof" Basement Drainage System BUILDINGS Accessories 23-3-27 Here's a new way to waterproof your basement from inside the house, eliminating the need to dig up your yard to lay tile around the foundation. Sanford Irrigation's drainage system consists of a sump dug into one corner of the basement, tied to a series of PVC drainage pipes that install under the basement floor. The first step is digging a 42-in. dia. hole 3 1/2 to 4 ft. deep. The company then uses a special, patented horizontal drilling process to bore lateral holes up to 50 ft. out from the hole. As the holes are drilled either parallel with the floor at a slight downgrade to the hole, 10-ft. lengths of 3/4-in. dia. slotted PVC drain pipe are inserted. Once the pipes are installed, a 50-gal. plastic basin is placed in the sump hole, equipped with a 1/3 hp sump pump. The pump connects to a discharge pipe that carries water away from the house. The last step is to install a manhole cover flush with the floor over the hole. "It's convenient and neat," says Paul Sanford, developer of the technique. "There's no disruption of yards, shrubs, concrete or decks." Sanford has installed the system in more than 900 homes in Minnesota and the Dakotas since coming up with the idea. Installation typically takes a day, he says. Cost for an average home with a 24 by 48-ft. basement is $2,900. The company will consider licensees.
