Crews excavate to the footing, apply a membrane coating, install French drains and footing drain tile, and regrade the lot so runoff moves away from the crawl space.
Rolesville soil and why crawl spaces fail here
Rolesville sits atop the Rolesville granite batholith, and Louisburg soils are coarse, sandy, and highly permeable near the surface. Rain percolates quickly downward until it strikes the clay and rock shelf beneath, where it pools instead of draining.
Water arrives fast and then has nowhere to go, so crawl spaces take on groundwater within hours of a storm even on well-graded lots. Standing water under the liner is the most common complaint here.
Large newer Rolesville homes usually justify a full encapsulation with interior drainage and a high-capacity dehumidifier rather than a partial repair.
