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

David in Clarksville, TN, called Frontier after noticing his bathroom floor was sagging and causing the tile to crack. During the inspection, the design specialist found standing water in the crawl space, mud marks around the perimeter, and insulation falling from between the floor joists. To restore support and control moisture, the Frontier crew removed the wet insulation and debris. SmartJacks were installed beneath the sagging area to lift and stabilize the floor. The crew then installed a perimeter drainage system connected to a sump pump at the lowest point, with discharge routed through IceGuard and a LawnScape Outlet. Once the water intrusion was addressed, the crawl space was encapsulated with drainage matting and CleanSpace liner on the floor, walls, and piers. A SaniDry Sedona dehumidifier was added to control humidity, and an EverLast Door was installed to help seal the space.

Existing Crawl Space Door

The existing crawl space door did not create a true seal, allowing humid air and water to enter the space.

Falling Insulation

Falling insulation indicates high humidity in the crawl space. The insulation absorbs moisture in the air, becomes heavy, and falls out of place.

Evidence of Water Intrusion

A buildup of mud on the edge of the vapor barrier indicates there was moisture intrusion. A visible line of moisture is also visible on the foundation wall.

SmartJack Installation

SmartJacks are installed where the floor lacks support, lifting it and restoring stability.

Drainage System Installation

The crew installed a drainage system to collect water at the point of intrusion.

Drainage Matting

Drainage Matting is installed as the first step in encapsulation. It allows lateral movement of water towards the drainage system.

Full Encapsulation

CleanSpace liner seals the ground, piers, and walls of the crawl space, preventing moisture and humidity from entering.

TripleSafe Sump Pump

Water from the drainage system enters the TripleSafe sump pump for removal. The UltraSump Battery Backup ensures the pump continues to work in a power outage.

External Drainage System

The sump pump discharges water through the IceGuard and LawnScape Outlet. The line is placed downhill from the home to prevent moisture from putting more pressure on the foundation wall.
