ABSTRACT:
A method for alleviating seepage of water through the foundation and/or into the basement of a building includes procedures for digging a trench along an exterior wall of the building's foundation, treating the exposed exterior wall surface to diminish its water permeability, providing a properly configured footer drain tile system for ducting water away from the footer of the foundation wall, and carefully filling the trench with an arrangement of selected materials that perform in a synergistic manner to achieve a desired combination of objectives. The footer drain tile system is positioned in the trench at a level below the top of the basement floor of the building. The materials used to fill the trench include a tiered arrangement of gradated stones, clay and topsoil. The stones define a porous reservoir and are arranged in a gradation of sizes, with the largest stones in lower portions of the trench and adjacent the footer drain tile. The top of the porous reservoir of gradated stone is capped by a densely packed layer of relatively impervious material such as clay. The sloped layer of clay is capped by a relatively porous fill of topsoil that also serves to close upper portions of the trench.
