Wendell soil and why crawl spaces fail here
Wagram and Appling soils around Wendell mix coarse gravelly sediment over clayey subsoil. The loose surface layer heats aggressively in eastern Wake summers, and warm soil drives vapor upward far faster than cooler upland clay does.
High summer soil temperatures accelerate vapor drive straight into framing above bare dirt floors, spiking crawl space humidity into the 80s by August. Subfloor sheathing delaminates and hardwood above begins to crown.
Newer Wendell Falls homes have decent grading, so most jobs here are liner, vent sealing, and dehumidification rather than structural work.
