Chapel Hill soil and why crawl spaces fail here
Chapel Hill's Wilkes-Enon soils weather from mafic igneous rock and accumulate as colluvium on steep, wooded slopes. Shallow depth to rock means infiltrating water rides the rock surface downhill and emerges as seepage at mid-slope, exactly where many custom homes are terraced in.
Hillside runoff is driven hard against uphill stem walls, saturating block and keeping crawl spaces dark and cool under heavy tree canopy. Low evaporation plus constant seepage yields some of the highest sustained crawl space humidity readings in the Triangle.
Split-level and stepped foundations around Meadowmont, Southern Village, and the historic Gimghoul area require staged liner details rather than a single flat installation.
