Given just how crazy 2020 weather has been in Louisiana, there’s really no telling what we should expect this winter.
One thing is for certain, however, and it’s that the frequent freeze/thaw cycles will affect your concrete.
While this is something that your concrete contractors typically take into account already, it’s important that you understand as well.
How the freeze thaw cycle of concrete works
When temperatures drop below freezing, the water or snow that your concrete has absorbed becomes frozen. This causes a slight expansion in your concrete, and when the weather warms up again, it thaws and contracts.
The constant movements within your concrete, no matter how slight they may be, undoubtedly have an effect on its durability. This can result in joint deterioration, spalling, cracking, and surface scaling.
Preventing concrete cracks during winter
Concrete is one of the most durable materials on the market. Its strength is determined by its ability to resist chemical attacks, weathering, abrasion, and weight.
Concrete that’s anticipated to experience harsh weather or other extreme conditions can be engineered to withstand even the craziest circumstances.
That being said, concrete that’s frequently subjected to freezing temperatures will need to be properly installed in order to counteract freeze/thaw cycles and not crack prematurely.
Expansion joints are a must-have for concrete that will be exposed to freezing temperatures. Their purpose is to isolate the concrete from the rest of the structural components.
Once the weather changes and the freeze thaw cycle of concrete occurs, these joints allow for movement between structural parts when necessary, and also restrict it in necessary places.
When investing in a project like a concrete driveway, it’s always better to be safe than sorry. Talk to your contractor about what you plan to park on your driveway, how often you plan on using it, and ask about concrete joints.
