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.
Zebulon soil and why crawl spaces fail here
The Goldston-rock outcrop complex around Zebulon is shallow and stony, with weathered slate near the surface. Thin soil over rock means very little storage capacity, so water perches immediately on the rock surface after every storm.
Large rural footprints with bare dirt floors push enormous volumes of moisture into subfloors, and joists over the center of the house sag first because those spans see the least air movement.
Rural Zebulon properties often combine crawl space work with gutter and downspout correction, since many farmhouses have no gutters at all.
Scope included in Zebulon
- Excavation to footing depth with membrane or elastomeric coating

Signs you need this
