What does rock salt do to my concrete garage floor?

Winter can wreak havoc on our homes, particularly when it comes to the garage. Snow, ice and rock salt make their way onto garage floors, creating more problems than simply a wet, sloppy mess.

Over the years, continued deposits of corrosive rock salt cause the concrete on your garage floor to flake and chip, resulting in an unsightly pitted surface. But the damage here goes far beyond the cosmetic. Once the top layer of your concrete starts to come off, those splotchy valleys formed continue to trap and hold the icy, salty water, allowing it to be absorbed into the concrete.

The pits become deeper and more pronounced from the rock salt, and the trapped water freezes and creates small cracks that develop into larger ones before you know it. Any water that doesn’t freeze, and doesn’t find its way into the drain, can accumulate at the edges of your garage floor, in the crevice where the wall meets the floor.  

The water-salt-freeze-thaw pattern causes a domino effect that can lead to significant foundation issues if left uncorrected.

To prevent ice and rock salt damage before it starts, or to stop the corrosion from continuing, I recommend a quality epoxy coating to cover your garage floor.

Our epoxy coatings can be installed over exiting garage floors, no matter what the temperature outside. They come in hundreds of different colors so you can take your floor from what it is now to virtually any level of wow, depending on your budget.

Aside from increasing the value and curb appeal of your home, an epoxy coating installed on your garage floor covers the entire surface and can fill in any cracks or crevices, permanently creating a barrier to rock salt, water, oil drips, gasoline, spills, dirt and more.

Unlike a concrete sealant, epoxy does not break down and does not need to be reapplied every year. It can withstand decades of abuse from the elements, and, in the long run, will save you a ton of time and money.
