Frost Heaving

Frost heaving can damage concrete and other masonry elements including sidewalks, patios, slabs, as well as retaining and foundation walls.

What is frost heaving?

When temperatures are cold, most materials will contract, or become smaller. When temperatures are hot, the heat does the opposite and triggers expansion. Water on the other hand holds different behaviors. Although water will expand slightly when heated and decrease as it cools; when it freezes, it expands, taking up an additional 10% more volume. When freezing water occupies a confined space it exerts tremendous expansive force at 20,000 lbs. to 80,000 lbs. per square foot. This type of extreme force will heave sidewalks, break apart a concrete patio, crack a foundation wall or even push a deck post up out of the ground

Other Causes of Concrete Heaving?

If it’s not freezing water, the culprit of concrete heaving could also be soil pressure. When clay-rich soil absorbs moisture it begins to expand. This force can be just as destructive as frost heaving. The solution to this cause is improving drainage by replacing the expansive soil with soil that has a higher sand and gravel content.

Our Solution

If a concrete or masonry element has been damaged due to frost heaving, it’s important to not only determine the cause but also which repair method will avoid heaving into the future. In many instances, drainage techniques can be used to prevent nearby soil from getting saturated with water. Other times, it may be necessary to install steel helical anchors or piers that connect the wall or slab to more stable soil that isn’t subject to freezing temperatures. Sometimes both preventative measures are used. We also use polyurethane foam to lift sunken concrete caused by frost heaving. This is Eco-friendly solution is the fastest most cost effective way to prevent liability by eliminating trip hazards.
