Sinking Floor Repair
Challenge
Clients had noticed their floor was uneven and sagging. When viewed from the basement it was very noticable that there was an issue and it needed to be remedied.
Potential Causes
Uneven floors are rarely caused by problems with the floor system itself. Instead, it's often a settling or shifting foundation issue that has impacted the floor system.
Floor beams and joists are made from wood that will usually bend or flex rather than crack or break. The same can't be said for masonry foundations. When soil issues cause a foundation to break, the floors above usually bend.
Sinking floors can lead to a variety of other issues, including jamming doors and drywall cracks.
In addition, uneven floors over crawl spaces are often accompanied by serious mold problems.
Solution
we can quickly and effectively repair a crawl space structural issue with our heavy-duty crawl space jacks. The SmartJack® system uses crawl space jacks are adjustable steel posts that will stabilize sagging crawl space structures.
During installation, we prepare a base of compacted engineered fill at all jack placement points, located directly beneath the main support beam. We install a precast concrete base on this fill, and then extend a crawl space jack between the base and the beam.
Once each jack's threaded rod is adjusted beneath the post, the weight bearing on the beam is transferred to the soil below. Additionally, this system allows the contractor to push a sagging floor back toward its original level position.
Our warrantied crawl space jacks can effectively stabilize your crawl space -- usually in a day.
