Crawl Space Structural Support Jacks

To be stable, strong and level, the floor above a crawl space requires solid mid-span support that’s usually provided by a post-and-beam assembly. But beams are often undersized, and many contractors use wooden posts that can rot, shift and settle. When this happens, floor joists sag and other structural problems occur. The IntelliJack® system is a foundation repair product that provides a permanent solution to these problems.

The IntelliJack® is also compatible with crawl space encapsulation systems, making it a good choice for homeowners wishing to eliminate moisture problems and improve home energy efficiency, while also solving structural problems.
