Topsoil used for slope away from foundation

Q.     I need to build up the area around my foundation to slope runoff away from it. What type of material do you suggest: ground stone, sand, topsoil, etc?

A.    Topsoil with a small amount of clay is best. Ground stone, sand and any other coarse material will allow water to percolate which defeats the purpose.

All you need is a slope of about two inches per horizontal foot. Plant and maintain a healthy stand of grass on this soil. Avoid shrubs and flowerbeds; keep them from six to eight feet away from the foundation in groupings you can enjoy from inside through your windows.
