ABSTRACT:
A drain conduit is disposed contiguous with and sealed to a footer which supports a foundation wall. The conduit is an upwardly open, impervious trough having an openwork cover. Any water leaking through the foundation wall or between the wall and the footer is captured by the drain conduit so that it does not enter the subsoil and weaken the support for the footer. Where the foundation wall has a crack opening onto its inner surface, it is enlarged and then covered by a moisture barrier film strip and a fiberglass panel, both of which are secured to the wall. Leakage water, through the crack, is thus channelized and directed towards the juncture between the inner surface of the wall and the upper surface of the footer for flow into the drain conduit. The panel terminates above the footer and film strip is extended across the footer and overlies the drain conduit. Where the foundation wall is formed of concrete blocks, holes are formed in the lower course of the blocks to drain their interiors onto the footer. Where there is a leakage flow path underneath the footer, the drain conduit is disposed beneath its lower surface.
