Advantages of the crawl space support system

Product Features

  • Holds loads heavier than 60,000lbs
  • Galvanized steel makes them corrosion resistant
  • Installs in limited-access areas
  • The ONLY crawl space support jack that addresses problem soils

If you want to achieve a durable, level, and secure floor above your crawl space, then you will need a solid mid-span support that is commonly provided by a post-and-beam assembly. Beams often fail, as they are undersized and comprised of wood that is subject to rotting, shifting and settling. Once your support posts sag, structural issues will occur.

The SmartJack® system provides a permanent solution to sagging crawl space joists, as they can be continuously adjusted to raise your floors back to a level position. During our crawl space repair system, we assure your below-grade space is dry and structurally sound, minimizing home damage overall and saving you money on costly future repairs.

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.

The 'Bulb of Influence'

Were you promised durable crawl space support posts, but found that they are starting to sag and settle? Load-bearing soils are crucial in assuring a sound crawl space structural repair and that is exactly why the SmartJack® system can't be beaten.

While many contractors argue for digging deeper during a support post installation, we excavate a 2' by 2' hole that is then filled with mechanically compressed, crushed stone. The cube of compressed, crushed stone disperses the weight and presses down into the soil outwards, applying an engineering principle known as the "bulb of influence."

When the transferred weight reaches the soil, 90% of the weight has been reduced, meaning that even if your soils are not strong, they will be able to support SmartJack®'s bearing load.

The SmartJack® system can't be beat
