Sandy topsoil over dense clay on graded lots. Moisture gets in easily and has nowhere to leave.
Centerville is a subdivision town, built mostly from the eighties through the two thousands on graded lots. Under those homes the soil profile is sandy on top and dense clay below, which means rain gets in easily and then stops. The upper ground stays wet and the crawl space feels it.
These crawl spaces are typically shallow, around eighteen to twenty four inches, with block perimeter walls and open vents. That is enough clearance to work in, and it keeps damp ground within inches of the subfloor. In August the difference between the outside air and the framing temperature is large enough to condense moisture on the wood.
Encapsulation removes the whole mechanism. Heavy liner across the ground and up the block, seams taped, vents sealed shut, and a dehumidifier to hold the space steady. Where fill settlement has dropped a pier we reset it first, because the liner should go over a crawl space that has already been made sound.
Here is what our crawl space encapsulation work includes on a Centerville home, in town or out toward the Houston County line.
