Water collects in the loose backfill around a graded foundation, and dense clay keeps it from draining away.
The backfill around a Centerville foundation is looser than the ground around it, so it collects water and holds it near the house. Underneath is dense clay that will not let the water drain down. That combination puts a steady supply of water at crawl space level after every substantial rain.
Whether that becomes standing water depends on the lot. Homes on the higher side of a graded neighborhood often shed it. Homes on the lower side collect from their neighbors as well as themselves, and those are the ones where a pump earns its place.
We set a basin at the low point of the crawl space, run perimeter drainage into it, and install a pump sized to what the space actually takes on. The discharge line runs beyond the backfill zone, which is the part people most often get wrong, because a short discharge just puts the water back where it came from.
Here is what our crawl space sump pump work includes on a Centerville home, in town or out toward the Houston County line.
