Angier soil and why crawl spaces fail here
Norfolk and Goldsboro soils near Angier are coastal plain sediments with a moderately well drained surface over a slowly permeable clayey subsoil. Seasonal high water tables commonly sit between one and three feet below grade.
Shallow groundwater forces vapor straight through the thin 4-mil poly most builders installed, condensing on the underside and pooling in wrinkles. The plastic looks intact while the soil beneath stays permanently saturated.
Angier's commuter growth has produced a large stock of 2000s homes where upgrading from 4-mil poly to a sealed 20-mil system is the single highest-value fix.
