These expansion joints aren’t just cracks and gaps… They’re invitations for weeds, water, and shifting slabs. I packed this one with play sand and a backer rod to get the depth right, then sealed it up with Sika self-leveling polyurethane and topped it off with a light layer of sand for a subtle finish. It’s a simple fix now that can save frustration later. Everything I used is linked in the bio if you’re ready to knock out a few cracks of your own. #DIYProjects #SidewalkRepair #fixedit
