How to Repair a Cracked Beam
LESLIE: Now we’ve got Frank in Texas on the line with a structural question. What’s going on at your money pit?
FRANK: Yes, I’ve got an older home, post-and-beam construction. I have about a 4×8 beam that’s cracked diagonally. And I’ve already poured a footer – a 2-foot by 2-foot by 6-inch footer – and I plan on bracing that. But what I’m wondering, once I jack it back into position, number one, is there an adhesive that might help hold it together? And on the sides, I want to marry in a support. Should I use OSB, plywood or 2×8?
TOM: What you would do is you would put another beam next to it that has to go the same width. It has to go bearing point to bearing point as the split beam. And then you would glue it with a construction adhesive from the new beam to the split beam. And I would bolt them together. And if you do that on a beam-by-beam basis, then it should be an acceptable repair.
It’s just a little tricky because you’ve got to get that new beam next to the old beam and it’s going to not be straight. And you’re going to have to work around wires and plumbing and such to get it in there and nice and tight.
But take your time fitting that beam. If you get the new beam in right, then it could be quite strong.
FRANK: Alright. I appreciate the advice. Thank you.
