High-Water-Table Sub-Slab Depressurization
Installing specialized condensation bypass loops and water-trapping fittings to prevent ground moisture damaging radon fans.
Henderson, Transylvania, and Polk Counties sit directly atop the Brevard Fault Zone and Henderson Gneiss, generating some of the highest radon readings in North Carolina.
Perched water tables and Brevard schist fractures create localized high-pressure radon gas pockets that penetrate slab perimeter expansion joints.
Certified mitigation crews operating out of Hendersonville and Brevard maintain high-capacity core drills, exhaust pipes, and NRPP-certified electronic monitors.
