We live in an area of deep winter freezing, and the potential for frost heaves is also real. It is interesting to note that not everyone understands just what a frost heave might be and how this phenomenon can harm a foundation. So, the frost heave is simply when freezing temperatures have penetrated deep into the soil. As more water is pulled in from unfrozen soil to the area of ice, it continues to build a “lens”. This forces soil above it to part and leads to a “heave” in the soil.
How on earth could that play a role in foundation damage? When the top levels of soil freeze and thaw (which creates suction), the pattern causes more and more water to be drawn into the area. This creates a lot of uneven pressure that can cause even a perfectly strong and well-made foundation to shift and crack. If that foundation is in an area of silt terrain or high water, the draining can be so poor as to leave the area at risk for regular frost heaves. NOTE: sand, gravel and grainy soils are much less likely to form frost heaves because of their overly porous natures.
Can you protect a home from the risks of frost heave? Actually, you can work with experts to make adjustments that can make it less likely to occur. For instance, experts say that you can:
Of course, this is a list of preventative measures that can only reduce the risks of foundation damage in the winter or spring seasons due to frost heaves. Even if you have experts step in and assess your risks; taking some of the preventative measures above, you may still find foundation damage in the winter months.
