What is Pitting in Garage Floors?

Pitting is a term used to describe the formation of small, concave depressions on the surface of the concrete.

These depressions can vary in size and depth and are usually caused by a combination of factors, such as freeze-thaw cycles, chemical damage, heavy loads, and poor installation.

Pitting can not only be an eyesore, but it can also lead to tripping hazards and weaken the structural integrity of the garage floor.

Common Causes of Pitting in Garage Floors

1 Freeze-Thaw Cycles

One of the most common causes of pitting in garage floors is the freeze-thaw cycle. When water gets into the pores of the concrete, it can freeze and expand, which puts pressure on the surface of the slab.

When the ice melts, it leaves behind small gaps and cracks, which can lead to pitting over time. This is particularly common in areas with harsh winter climates.

2 Chemical Damage

Another common cause of pitting in garage floors is chemical damage. Chemicals such as oil, gasoline, and salt can penetrate the surface of the concrete and break down the bond between the cement and the aggregates. This can cause the surface of the slab to deteriorate and become pitted over time.

3 Heavy Loads and Impact

Garage floors are designed to support heavy loads, such as cars and other vehicles. However, if the load is too heavy or the impact is too great, it can cause the surface of the concrete to crack and become pitted.

This is particularly common in areas where heavy equipment is used.

4. Poor Installation

Finally, poor installation can also lead to pitting in garage floors. If the subgrade is not properly prepared, or if the concrete mix is of poor quality, it can lead to weak spots on the surface of the slab, which can become pitted over time.

Preparing Garage Floor Resurfacing

Before resurfacing your pitted garage floor, it’s crucial to prepare the surface properly. This includes removing any debris, oil stains, or loose material from the floor.

Make sure to use a broom, scraper, or pressure washer to clean the surface thoroughly. Remove any stubborn stains with a degreaser or detergent.

After the resurfacer has dried, it’s time to sand the surface again to create a smooth, even finish. Use a sanding machine to sand the surface, and wear protective gear such as gloves, goggles, and a mask.

Step 6: Sealing the Surface

After sanding, it’s crucial to seal the surface to protect it from future damage. Choose a high-quality concrete sealer that is appropriate for your garage floor.
