Customer Question

I have a cracked floor joist in basement. I am planning on attempting to jack it up in hope of closing the crack, then putting liquid nail in crack and on each side of joist. Attaching an 8ft 2x8 it will run 5 ft to right of crack to rest on foundation and 3ft. to left ( can't rest on cross beam though due to heating duct) I will then attach with 3/8 lag bolts every 6in. or so in zig zag pattern.

Hello and thankyou for using this service!

I am sorry to hear about the problem you are having with your foundation

Sounds like you are right on track with the way you want to go with it.

The only problem I would have with it would be using lag bolts. You should clamp your scab to the broken joist and drill thru both and use a carriage bolt with a washer on each side.

Double up on the nuts and tighten them against each other to lock them in place.

The lag bolts can become loose over a period of time. The bolt will not.

When you are ready to tighten them up glue them together and assemble.
