Crawl Space Repair Photo Album: Crawl Space Repair in Ashland City, TN

Bobby in Ashland City, TN, contacted Frontier after noticing signs of moisture in the crawl space. During the inspection, the design specialist found efflorescence on the foundation walls and mold growth on the floor joists, both signs that excess moisture had been present in the space for some time. To help keep the crawl space dry long term, the Frontier crew installed a perimeter drainage system to capture water before it could collect around the edges of the crawl space. The system directs water to a TripleSafe sump pump for removal from the home. The crawl space was then encapsulated with CleanSpace Drainage Matting and a CleanSpace liner to help isolate the home from ground moisture. To manage humidity and reduce the risk of future mold growth, the crew also installed a SaniDry Sedona dehumidifier and an EverLast Door to better seal the space from humid outside air.

Moisture Evidence

The foundation water shows that water was standing in the crawl space at one time, leaving a line of moisture on the wall. Efflorescence above that line shows where water seeped through the blocks and evaporated into the space.

Mold Growth

Persistent moisture has created an environment where mold can thrive. The process of encapsulating and dehumidifying the space dries out the mold and makes it dormant.

Drainage System

To prevent standing water, the Frontier crew installed a drainage system around the perimeter of the crawl space.

TripleSafe Sump Pump

The drainage system feeds into a TripleSafe sump pump, which removes the water from the crawl space.

IceGuard and LawnScape Outlet

The water removed by the sump pump exits through a LawnScape Outlet directed downhill from the home. The IceGuard ensures water can still escape the line if the pipe were to become blocked or freeze.

Drainage Matting

Drainage matting is installed beneath the CleanSpace liner, allowing lateral water movement toward the drainage system.

Full Encapsulation and SaniDry Sedona Dehumidifier

CleanSpace liner covers the floors, walls, and piers of the crawl space to ensure moisture cannot enter from the ground or walls. A SaniDry Sedona dehumidifier catches any remaining moisture from the air and removes it through the sump pump.

Preventing Leakage from Water Heater

Water heaters are prone to leaks. The CleanSpace liner is attached at a slightly higher point on the water heater, so any leakage can flow under the drainage matting towards the drainage system.
