How to Scab a Floor Joist With Plywood

Plywood is an excellent material that can be used to Scab (not sister) a notched floor joist. In this video i use 1-2 layers of 3/4" plywood with 16D nails applied in a staggered pattern at approx. 6-8" O.C. C
Consult a local engineer for the requirements based on your specific project and scenario- this is not universal advice that can be freely applied to any project.

Plywood is actually stronger than dimensional lumber. No such thing as too much construction adhesive; do not use wood glue. The nails are only there till the glue dries. Better to use structural screws than 16d nails, makes it all tighter like plywood but more like a lam beam. GRK screws come in lengths up to 4". I've done this and over-nailed (too many) with 8d ring-shank nails. Keep it all as tight as possible.
