Bouncy floors are common in homes with a crawl space. The problem is often caused by poor design, foundation settlement, or a groundwater or moisture problem in the crawl space. Standing water and excess moisture should be addressed before fixing the structural problem in your crawl space. Once the crawl space is dry, the SmartJack System can be used to lift and stabilize the beams and floor joists to help rid your home of squeaky floors. The weight of the home is transferred to a solid base of engineered fill. Steel columns are secured to the beams or joists and heavy-duty rods allow for adjustment.
