Rain water is deflected from the foundation wall of a building structure by a flashing of non-ferrous metal that is fastened to the foundation below the grade level of the soil. Soil is trenched and exposed about the foundation, and the flashing is installed in the trench around the perimeter of the foundation wall. After installation, the trench is backfilled with soil thereby covering the flashing and restoring grade. During heavy rains or floods, water seeping into the soil is deflected away from the foundation by the flashing. This prevents water from pooling at the bottom of the foundation and seeping up into the structure through the joint where the foundation meets the basement floor.
