This kit repairs notched, driller or other similar types of floor joists damage without the need to have to remove plumbing or wiring which may go through the joist and without the need to sister alongside another joist.. The kits consists of a steel strap that is screwed to the bottom of the floor joists. The kits comes with everything needed including the strap, screws, drill bit for pre-drilling the holes and a ratchet driver to install the screws. Once the strap is installed it will restore the full strength of the floor joists. There is an engineered design report available that can be provided to a Building Department if required.
