Perimeter and transverse troughs, possibly 3-5 inches wide and deep, can be formed in an existing building subterranean concrete floor, with the perimeter trough being immediately adjacent and extended along the foundation wall and the traverse trough connecting the perimeter trough to a nearby sump pit formed in the floor. Each trough can be formed by cutting narrow shallow grooves outlining its desired location, and then breaking away the concrete there between. Water seepage through the wall will collect in the perimeter trough and drain away via the transverse trough to the sump pit, eliminating water pooling on the building floor itself. The troughs can be covered by separate metal or plastic covers, secured by adhesives, sealants and/or nails relative to the floor and/or foundation wall.
