Each crawl space jack post is assembled in your crawl space. The top of the crawl space jack is mounted against the girder, and the installation is carefully plumbed.
In cases where existing girders are undersized or damaged by rot, a new sister girder may be installed alongside the original in order to strengthen and reinforce the structure.
Each IntelliJack® is then tightened in an attempt to lift the floor back to its original position. In many cases, your contractors will be able to straighten and level floors, close cracks in walls, and halt future downward movement. The jacks will continue to be adjustable for future tightening, should you need it.
