Floor Joist Support Systems

While some floors are built directly on a concrete slab those built above open areas such as crawl spaces basements and lower floors almost always use a floor joist system to provide weight bearing support for flooring furniture people and everything else in your home.

Floor joist support systems.

This engineered and patented design distributes the wall loads more evenly to the floor joists reducing side pressure which in turn prevents the wood joists from twisting or buckling like in other basement wall straightening systems that push off only one or two floor joists. The joist support helps reinforce the floor so it can handle the weight load it needs to. A joist support is the horizontal beam that supports the floor joists. Solid blocking should be used where floor joists overlap over beams.

Each smartjack post rests on a precast concrete pad that is set on a base of compacted stone. The best way to permanently solve sagging bouncy floor problems is to install smartjack posts beneath the beam that supports your crawl space joists. In some cases additional joist supports will have to be installed before there can be extra heavy objects on the floor. These reinforcing joists install quickly in crawl spaces with a complete installation taking about a day and provide a permanent solution.

It should be placed at eight foot intervals between any floor joists 2x10 or longer.
