What Causes Concrete Spalling?

If you have an old concrete patio that may have been poured many decades ago, it most likely has some pitting, chipping, or surface flaking. This is what concrete professionals call spalling—and it’s not pretty. What causes concrete spalling? This article explains what causes it and how Gruttadaurio Masonry may be able to make your concrete look like new.

 

Spalled concrete can be caused by:

  • Freeze-thaw damage due to our Upstate New York, weather: When water seeps into your concrete and freezes, it expands which can cause the surface to chip, and crack.

  • Rebar Corrosion: When underlying metal rebar within the concrete corrodes, it pushes against the concrete and causes spalling.

  • Chemical Damage: When you expose your concrete to chemicals like salts and deicing agents, this can lead to spalling.

  • Concrete Contractor Error: Spalling can also occur is if a concrete contractor did not prepare the concrete mix properly before pouring or did not use best practices when finishing.

What Can I Do to Fix Concrete Spalling?

The first thing to do is to call Gruttadaurio Masonry at (315) 310-7193 to set up a free, no-obligation onsite evaluation of your concrete. After inspecting your concrete area, we’ll make recommendations for the best way to approach the damaged concrete. There are several approaches our concrete spalling repair experts may recommend:

 

For minor spalling damage we will call in our concrete repair experts, CONCRETE DOC+, a division of Gruttadaurio Masonry. There are several ways they will approach doing the concrete repair, depending on the extent of the damage.

 

  • Surface Patching Method:

    Our concrete professionals will remove any loose concrete, prepare the surface, and fill in the chipped areas with a patching compound. After the curing time is complete, a sealant will be applied to help prevent future surface damage.

 

  • Concrete Resurfacing Method:

    If your concrete has more extensive damage, you may want to consider concrete resurfacing. This is when new concrete is laid over the entire surface after proper preparation has been done. Not only will this make your patio look like new, this is a good opportunity for you to create a brand new look to your area. You can choose to add a new integral color to your concrete to liven up your outdoor living space. To add a decorative treatment, CONCRETE DOC+ can create a beautiful stamped concrete surface. The stamps used can mimic various types of stone, slate, brick, and even wood planks. You can choose from a variety of colors, textures, and patterns. We recommend adding an accent color to the surface of your stamped concrete, also known as antiquing. This will add depth and bring out the details of the stamp for an even more realistic look.

Sometimes our cosmetic concrete restoration services may not be enough. In some cases, the entire slab may need to be replaced if the damage is severe enough due to structural issues. That’s when Gruttadaurio Masonry steps in. This would require that the existing concrete be torn out and a brand-new concrete slab be installed. Gruttadaurio Masonry offers free, on-site inspection of your concrete and will provide a free detailed estimate.

 

How Can I Prevent Concrete Spalling?

  • Ensure Good Drainage

When installing a new concrete patio or pool deck, your concrete contractor will need to ensure that it is graded for proper drainage. In certain instances, a drainage system can be installed. Of course, Gruttadaurio Masonry takes all the necessary steps to ensure that will not pool causing potential damage to your concrete.

  • Proper Concrete Mix is Vital

One of the ways to prevent spalling is to hire a concrete contractor who is reputable and ensures that the concrete mix they use has the correct water-to-cement ratio and has been properly cured.

  • Use High Quality Materials

Your concrete contractor should be using the highest quality concrete materials and reinforcements that are resistant to chemical and environmental damage.

  • Apply a Concrete Sealer Regularly

For new concrete patio surfaces, after the concrete has properly cured, your concrete contractor will need to apply a sealant to prevent water from penetrating the porous concrete. To help keep your concrete in top shape, you should reseal your concrete every few years.
