Product Features

  • Supports loads of more than 60,000lbs
  • Galvanized steel for corrosion resistance
  • Installs in limited-access areas
  • The ONLY crawl space support jack that addresses problem soils

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. Unfortunately, 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 SmartJack® system is a foundation repair product that provides a permanent solution to these problems. The SmartJack® is installed by attached steel support beams to your floor joists and a sturdy base at the floor. Once all posts are installed, they are adjusted to raise your floors to a level position.

The SmartJack® system can be easily adjusted at any point if your home requires it, ensuring that you have a permanent solution to your problems. The SmartJack® 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.
