I have a 2x10 floor joist that has a vertical crack from about the bottom to half way up (also 2 knots at crack). There also appears to be some longitudinal cracks that follow grain lines The joist is under bathrooms. About 5’ from the crack they cut a chunk from the joist for the bathtub drain.. This joist may be 1/4 inch low. My plan was to cut some ¾" plywood I have on hand 4’ long and as deep as the joist. I plan to use a post support (the kind with the screw in the top) and jack the joist up some and "sister" the plywood to the joist (w/the crack centered in the 4’ width of the plywood. Is plywood a good method? Should I plywood both sides? Should I glue the plywood to the joist (will not be able to remove if glued)? Should I bolt or screw the plywood to the joist? Pattern and bolts sizes? Pattern and screw sizes?
