Concrete is a popular building material for good reason – it’s strong, durable, and can be used in a variety of applications. But concrete isn’t immune to damage (spalling concrete) – just ask any driver who has had their windshield smashed by a rock while driving on a freeway.

Inspect the Concrete

The first step in preventing spalling concrete is to inspect the concrete for signs of damage. If any cracks or chips are visible, it is important to take action to prevent the concrete from spalling. Concrete that has begun to spall can be difficult and dangerous to remove and can cause serious structural damage.

Seal the Cracks and Chips

If there are any visible cracks or chips in the concrete, it is important to seal them up as best as possible. This can be done with a variety of sealants, including epoxy, silicone, and polyurethane. Once the cracks have been sealed, it is important to roughen up the surface of the concrete so that water cannot seep in and cause further damage.

Apply a Protective coating

Once all of the cracks have been sealed and roughened up, it is time to apply a protective coating. This coating will help protect the concrete from moisture and other environmental factors. There are a number of protective coatings available, including acrylics, polyurethanes, and epoxies.

Remove any Debris that May be Causing Damage

There are a few things that you can do to prevent spalling concrete from happening. First, remove any debris that may be causing damage. This can include pieces of concrete, rocks, or other objects. Next, make sure the resurface concrete is smooth and free of any cracks or bumps. Finally, seal the surface with a coat of paint or a sealant.

Call a Spalling Concrete Professional

There are a few ways to prevent concrete spalling from happening. One way is to make sure that the concrete is properly mixed before it is poured. Another way to prevent spalling is to use a coat of sealer after the concrete has been poured. If you are experiencing spalling concrete, it is best to call a spalling concrete company to assess the situation.

Apply a Primer or Coating

There are a few ways to prevent spalling concrete from happening. One way is to apply a primer or coating before the concrete is poured. This will help to protect the surface from moisture and other contaminants that could cause spalling. Another way is to use a sealant after the concrete is poured. Sealants can help to prevent moisture and other contaminants from reaching the surface of the concrete, which could lead to spalling.

The difference between cracking and spalling

Cracking is a form of deterioration where the surface of a concrete slab or foundation starts to break away in thin sheets. Spalling is a form of deterioration where chunks of concrete break off and fall to the ground. Visit to learn more about the difference between cracking and spalling concrete.

Use an epoxy or polyurethane sealant

Epoxy and polyurethane sealants are effective at preventing spalling concrete. They are available in a variety of colors and can be applied using a variety of methods, including spraying, brushing, or dipping. Sealants should be applied to areas where concrete will come into contact with water, such as around drains and waterlines. They should also be reapplied every few years as the concrete becomes worn down.


By following these simple steps, you can help prevent your concrete from spalling and keep it looking new for longer.
