Guide To Preventing Cracks In Your Concrete Driveway

Posted on

Concrete is one of the sturdiest materials that you can use for your driveway, but nothing is perfect in this world; hairline cracks can develop in concrete. You should do your best to prevent these hairline cracks from expanding, and you can do that with the following guide.

Temperature And Your Driveway

There are several things that could cause your driveway to crack, like temperature. Concrete contains air bubbles that help the material expand and shrink when the temperature changes. These air bubbles help maintain the integrity of the driveway's overall structure, but this system is not perfect and could fail under extreme duress.

You should prepare your driveway for both hot or cold temperatures. Follow some of the following tips for the winter:

  • Seal any cracks that might let water or snow into your concrete, which could further damage your driveway (even lead to weeds).
  • Have your driveway specialist seal your driveway with a lithium silicate sealer for snowy areas to protect your driveway from excess sodium damage. This should prevent moisture from seeping into your driveway.

You should also be sure to protect your driveway during the summer with the following tips:

  • You need to use an acrylic silicone solvent-based sealer, sodium silicate sealer or siloxane concrete sealer, which should protect your driveway from expanding (leading to cracks) due to extreme heat and also keep the color from fading due to UV lights. 

You can seal your driveway on your own. Or, if you are not comfortable with this task, you can have your concrete specialist take care of this maintenance. 

Be Mindful Of Heavy Loads

Concrete can handle heavy loads, but be careful of leaving these loads on your driveway for days because the weight can stress the concrete more and more over time. You may even force small hairline cracks to expand, which can only grow with extreme temperature fluctuations. 

Think About Having Your Trees Serviced

Roots have a way of expanding and do not recognize boundaries like your driveway. Your best bet is to talk to a tree service specialist about making sure your trees are not forcing their roots onto your concrete driveway because, given enough time, they can cause a crack. 

You can talk to your concrete specialist about other things that you can do to help preserve your driveway and prevent cracking.  Remember that a good concrete driveway can last 25 to 50 years, even when crack filling is completed.
