Crawl Space Repair Photo Album: Crawl Space Repair in Greenbrier, TN

Kent reached out to Frontier for an inspection of a home on the market in Greenbrier, TN. During the evaluation, the design specialist found efflorescence on the foundation walls, mold on the floor joists, and a muddy vapor barrier showing signs of standing water in the crawl space. To restore the space, the Frontier crew soda blasted the floor joists and boards to remove and eliminate mold. They installed a drainage system with a sump pump to collect and discharge water away from the home, along with an IceGuard and LawnScape outlet for reliable drainage. The crawl space was then encapsulated with drainage matting and CleanSpace liner, and a SaniDry dehumidifier was added to control humidity and help keep the space dry moving forward.

Efflorescence and Pooling Water

The white, chalky substance on the foundation wall is efflorescence. These are minerals left behind when water moves through the concrete and evaporates in the crawl space. The mud on the liner is evidence that water had pooled in the space at some point and then evaporated, leaving the soil behind.

Soda Blasting Treatment

Soda blasting removed mold from the surface and crevices of the wood in the crawl space. Baking soda used in soda blasting raises the pH of the wood, inhibiting mold growth.

Drainage System

When water is pooling in a crawl space, a drainage system is often recommended. It collects the water and directs it to a sump pump, which then removes it from the home.

Drainage Matting Installation

Drainage matting is installed beneath CleanSpace liner to prevent water from pooling.

SaniDry Sedona Dehumidifier

The SaniDry Sedona Dehumidifier will keep the crawl space dry year-round, preventing mold growth.

TripleSafe Sump Pump

The TripleSafe sump pump will collect any water from the drainage system and discharge it away from the home.

CleanSpace Liner and RimTite

The CleanSpace liner seals the crawl space floor to prevent ground moisture from evaporating and raising humidity levels. RimTite insulation and SilverGlo panels are used to seal gaps and cracks in the foundation walls, including areas where HVAC ducts pass through.

IceGuard and LawnScape Outlet

The sump pump is connected to an IceGuard and a LawnScape outlet, which discharge the water safely away from the home. The discharge line is typically extended about 8 feet downhill so the water flows away from the foundation instead of back toward it.
