Crawl Space Repair Photo Album: Crawl Space Encapsulation in Rock Island, TN

Michael in Rock Island, TN, contacted Frontier after his pest control company alerted him to mold growth beneath the home. During the inspection, the design specialist found mold on the wood surfaces as well as areas of the floor system that had begun to sag. The home had multiple additions over the years, resulting in two separate crawl space areas that required protection. To restore stability, the Frontier crew installed SmartJacks to help support and stabilize the floor system. While soda blasting was recommended to remove the existing mold, the homeowner chose to focus on controlling the conditions that allow mold to grow by addressing the moisture problem. To manage water intrusion, the team installed a drainage system in the area most affected by runoff and directed collected water to a TripleSafe sump pump for removal from the crawl space. The crawl space was then encapsulated with drainage matting and CleanSpace liner to help isolate the home from ground moisture. A SaniDry Sedona dehumidifier was installed to control humidity levels and help keep mold dormant. An EverLast crawl space door was added to help seal the space from outside air and moisture intrusion.

Mold Growth

Humidity in the crawl space allowed mold to grow under the home, weakening the floor system and reducing air quality on the first floor of the home.

Removing Debris from the Crawl Space

The crew begins the job by removing debris from the crawl space, which often includes old vapor barrier material and insulation.

Drainage Trench

A trench is dug in the crawl space so the drainage system can be installed in the ground, allowing it to catch water if it flows through the space.

Drainage System

Homes built on a slant often have one side of the home with worse water intrusion through the foundation. The drainage system was installed to collect water entering from that side.

SmartJack Installation

SmartJacks were installed throughout the crawl space to lift and stabilize the floor.

TripleSafe Sump Pump Installation

The drainage system directs water towards the TripleSafe Sump Pump, which has one pump for low water intrusion, a second pump for heavy water intrusion, and a third battery backup pump for power outages.

Full Encapsulation

CleanSpace is a 20 mil thick liner with an antimicrobial additive. It covers the floor, walls, and piers to seal off the space from moisture intrusion.

SaniDry Sedona Dehumidifier

Mold grows if any moisture is introduced to it, so dehumidification is an essential part of the encapsulation process. Frontier installs the SaniDry Sedona Dehumidifier to keep relative humidity levels under 60%.

EverLast Door

The EverLast Door is custom-cut and installed to seal the crawl space entrance.

Proper Drainage

The TripleSafe Sump Pump directs water through a PVC pipe towards the LawnScape Outlet, placed downhill from the home to prevent water from reentering the space. An IceGuard is installed at the exit to ensure water can still escape if there is a block in the line.
