It’s winter and I just got back from the mail box and noticed one of my driveway slabs has heaved. This in addition to a sidewalk section that has moved too. I noticed this last year about this time, so what gives?

Frost heave. The differential in moisture content in the soil as it freezes causes the sections to raise at differing rates.  The same thing can happen in the summer if you have expansive soils like clay. As they uptake moisture they expand as much as ten percent!

I’m kicking myself, I noticed the expansion joint needed to be caulked this fall but didn’t get around to it. Most of the time the slab will settle back down just fine but occasionally as that section is heaved additional material works itself under the slab and it doesn’t drop.

Caulking joints, using a concrete sealer and controlling water runoff are preventive steps that can and should be taken to minimize slab heaving.

If your concrete is not how you would like it call the concrete raising and leveling professionals today,
