They needed to update their SmarJacks. The home was starting to settle
The SmartJack system permanently lifts and stabilizes existing beams and floor joists in your crawl space. A solid base of engineered fill addresses the problem of weak foundation soil by transferring the weight of the home to competent strata. Steel columns are secured to the beams or joists in the crawl space. Heavy-duty, threaded rods allow for adjustment and a custom fit for each SmartJack system installed.
