Have your concrete re-coated with an overlay, freeze-thaw cycles, de-icing salts, poor finishing techniques, improper curing, poor concrete mix. For larger areas of pitting and chipping, we recommend using a 100% epoxy concrete patch with a sand aggregate. The silica sand is mixed with the epoxy resin to act as a filler. The HD-110 concrete patch from Legacy Industrial is a good example of this.
If the surface of the driveway has peeling concrete, then most likely, the cause is an installation error. Common mistakes include adding too much water to the mix to facilitate pouring; spraying the concrete surface with water to prolong the finishing time; and not curing the concrete properly after installation. It's not uncommon for contractors and concrete builders to receive calls from customers asking why their concrete is peeling and chopping and how the problem can be solved. Descaled concrete may resemble round or oval depressions along surfaces or joints.
Descaling tends to be more common in cold climates when defrosting chemicals are applied or when seasonal freeze-thaw cycles damage concrete. First, 1 gallon should be enough to repair 8 to 10 square feet of chipping, with a depth of ¼ inch. Use this diagram to help you place the concrete screed strips and “picture frame strips” you'll need when re-paving your driveway. In general, for a garage, the depth of damage is usually less than ¼ for peeling and ½ for some bites.
Splinters can appear because the rebar has been exposed and moisture and water have started to rust the rebar or because the concrete joints were built incorrectly. Polymer-modified cement patches are a good choice for areas with very deep pits, broken concrete lips and edges, deep holes, and other areas where repair may need shaping, such as the edge of a concrete pad. If you have some holes due to pitting or localized peeling, this is where epoxy concrete respavers will work best. Once you're done and the repairs have cured, you may need to lightly grind any ridges or areas where the mixture hasn't melted well with existing concrete.
I found that this always had to be a subfloor, as they used a lighter concrete with a porous stone like vermiculite in the mix. What happens is that water settles on the garage floor and makes its way to the capillaries of the concrete. They are also a good choice if you only want to seal the concrete of the elements after making repairs, as they are available in a natural gray finish and can be troweled. The reason why people delay their fancy garage floor projects is not because the concrete splinters or pits.
The remedies for chipping vary depending on the severity of the problem, the type and location of the concrete structure and other factors.
