Concrete Maintenance: Freeze-Thaw Cycle
What is the Freeze-Thaw cycle?
The freeze-thaw cycle can create many problems for Western New Yorkers. Freeze-thaw refers to the cycle created in colder climates where moisture settles below the surface, freezes and expands. This naturally occurring, unavoidable process can cause all kinds of headaches for home and business owners who don’t prepare accordingly before the weather starts to turn.
Why is it Bad for your Concrete?
When water freezes, it expands to about 9 percent larger than its liquid state. As moisture seeps below the surface and temperatures drop below freezing, it produces pressure within the pores of the concrete. When the pressure caused by this expansion exceeds the strength of the concrete, you could be looking at a potential problem. Spalling, scaling, crumbling and cracks can all form as a result of the freeze-thaw cycle.
How can I save my concrete surfaces?
Sealing
When it comes to combating the freeze-thaw cycle, a little preventative maintenance can go a long way. When applied properly, sealing your concrete creates a protective barrier over the top layer of your surfaces. This protective layer can help prevent moisture for settling below the surface, and protect your concrete from stains caused by automotive fluids and other road debris.
De-icing Chemicals
De-icing chemicals such as sodium chloride, calcium chloride, magnesium chloride, and potassium chloride are a double edged sword. On one hand, when used sparingly, de-icing chemicals can reduce the freezing point of the precipitation as it falls on your pavement, preventing ice from forming in the first place. However, if your surfaces are not already sealed the de-icing chemicals themselves can cause your concrete to degrade over time and negatively impact the surrounding vegetation.
