Floor Joist Support Systems

A joist support is the horizontal beam that supports the floor joists.

Floor joist support systems.

Each smartjack post rests on a precast concrete pad that is set on a base of compacted stone. In some cases additional joist supports will have to be installed before there can be extra heavy objects on the floor. Providing more support and rigidity than cross bracing solid blocking is a reasonable alternative but can be an obstacle for running plumbing pipes and electrical wire between floor joists. It should be placed at eight foot intervals between any floor joists 2x10 or longer.

Solid blocking should be used where floor joists overlap over beams. Crawl space joist supports are steel adjustable support posts that are installed to repair sagging floors. Fixing basement walls perpendicular to the floor joist unique in the industry the perpendicular gorilla wall braces utilize the support of three floor joists to straighten bowing basement walls. These reinforcing joists install quickly in crawl spaces with a complete installation taking about a day and provide a permanent solution.

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.
