The homeowners had created a staked and shimmed supports to help the sagging floor. Unfortunately, this was only a band-aid that was no longer effective.
The floor joists in the home had become so rotted due to the open crawl space vents allowing humidity to enter the space.
New, pressure treated floor joists were sistered to the older, failing joists.
The CrawlSeal Encapsulation system and sealed vents prevents ground and outside moisture from entering the space, while the IntelliJack system stabilized and leveled the floors.
The Tar Heel self-draining dehumidifier will keep humidity levels low to prevent future mold growth and wood rot.
After a year of dealing with mold growing in the living area of the home and bouncy floors, the Thomasville, NC homeowners did not know where to turn for a reliable solution. After a thorough inspection from their termite inspection company, the homeowner’s had confirmed the floor system in their home was beginning to rot, not from termites but moisture. The homeowner’s were in a need of a reliable company that would find a permanent solution.
After a very thorough inspection and review of the problems the homeowners were faced with, System Design Specialist, Ryan Arnett designed a solution that would stabilize their floor system using the IntelliJack system and prevent mold growth from spreading throughout the crawl space and living area of the home by sealing the crawl space.
In the Piedmont region of North Carolina, red clay is prominent, once clay becomes damp or wet, it expands. Because of this, the long-term exposure to ground water moisture has caused the piers in the home to settle and shift as the clay floor expands.
The crawl space team began the transformation by correcting the moisture problem to allow the clay to dry. The CrawlSeal system is as thick as a pool liner to prevent rips and tears and was installed along the entire crawl space floor, fastened to the walls and each pier in the home. The open vents that were previously allowing for humidity to gather in the crawl space were sealed using the X-Grade Crawl Space Insulation panels. The inorganic insulation panels have a silver glow that reflects heat back into the crawl space and cannot become affected by moisture. Now that the home was completely separated from the exposed clay floor below and all outside air was sealed off, the self-draining Tar Heel dehumidifier and condensation pump were installed to keep humidity levels below 55% and condition the crawl space air.
Because the wooden floor joists on either side of the girder had previously become affected by moisture, many of the joists had to be sistered to new wood in order to help strengthen the overall floor system. As the floor joists became stronger, a galvanized steel beam was installed perpendicular along the floor joists and the steel IntelliJack system was fastened into place every few feet. Fourteen (14) heavy-duty IntelliJacks were then adjusted to the appropriate height to stabilize and lift the floor system back to the correct height, immediately.
The homeowners now have a conditioned and stabilized crawl space and floor system that will last them for many years.
