Preventing Frost Heaves in Walkways and Driveways
As Spring finally comes around and the temperature begins to creep above freezing, we enter a period of repeated freeze-thaw cycles at night. When this occurs, you may start to notice frost heaves in your walkway, patio or driveway. What you are seeing is not unlike the frost heaves you experience driving your car. You know – when you see signs along the road that say “Frost Heave” and you’re wondering “Where?” And then, BOOM, you nearly hit your head on the roof of your car. THAT’S a frost heave. The solution is to prevent water from penetrating the surface. Ensure it drains away properly instead of sitting below and expanding enough to ruin your finished surfaces.
