Thrasher Foundation Repair Before & After
  • Crawlspace Repair in Eminence, MO
    Crawlspace Repair in Eminence, MO

    Crawlspace Repair in Eminence, MO

    This crawlspace was experiencing an array of issues. It was extremely damp and had high humidity. This weakened the floor system, allowing it to sag and drop under the weight of the home. We encapsulated the entire crawlspace to fix these issues, making it a controlled environment. We then installed a Sedona dehumidifier to dry out the crawlspace and flooring system and prevent any future mold growth. Then we installed 8 galvanized steel beams and 16 smart jacks to to permanently stabilize the floors and lift them back into place, closing the gaps between the walls and ceiling.

    Susan was having issues with her crawlspace getting moisture in the area. Moisture in a crawlspace can cause further damage to the floor joints below, such as mold, rot, and beam failure. The crawlspace of your home must be protected to ensure there is no moisture getting in. This can affect your home above.    For this project, CleanSpace was installed, which is a thick liner, like one in a pool. There was a drainage mat put underneath the CleanSpace, to ensure water and moisture can flow freely beneath the lining, and into the Sump Pump that was installed. A Sump Pump was put in, to help maintain a dry crawlspace, with the final product being a drain line, to help get the water out of the crawlspace. Susan can now rest easy that her crawlspace is protected from the elements.

    Sagging Floors and Wet Crawl Space Fixed in Marshfield, MO

    Darrell and Dixie N. have been doing work on their home and wanted to make sure that the foundation was stable. Darrell and Dixie noticed that the drywall was cracking and the floors were buckling. Concerned that they work they have done on their home would be worth nothing, they decided to call Thrasher for a permanent solution that wouldn’t cause any more problems. The crew went out to their home and saw that the crawl space had water, the floor was buckling, and drywall cracks were throughout the home. We installed 22 SmartJacks to lift and stabilize the floor. We also put in a sump pump and fully encapsulated the crawl space with CleanSpace so the space would stay dry. Darrell and Dixie were very excited to no longer have to worry about the floors or crawl space.

    Susie is a homeowner in Marshfield, MO, and needed some help with her crawl space. The crew went out to her home and recommended encapsulating and giving the beams support. They started with the walls and encapsulated them with Clean Space to keep all of the moisture out. Then to offer the floor much-needed support they installed Smart Jacks with a new supplemental beam.
