Soil Conditions & Foundation Types in Princeton, NJ

Clay-dominant ground conditions, which are prevalent throughout much of NJ, retain moisture longer and create sustained lateral pressure against foundation walls.

Princeton and surrounding Princeton, NJ communities contain buildings from multiple eras with very different waterproofing realities.
