Abstract
Abstract A drainage apparatus for basements includes a conventional block or poured concrete wall supported by a footer having an excavation at its inner side extending to the same level as the lower part of the footer, with an aperture and drain tile positioned in the excavation and extending the length thereof. A cover plate means extends from the drain pipe over to the wall for end support on an inner ledge means on the block wall, whereby a floor section can be laid over the cover plate and drain tile to blend into the remainder of the basement floor.
