Major Forms of Concrete Damage that Require Replacement

Concrete floor with polyaspartic coating

Concrete preparation is a crucial step in any garage floor epoxy and polyaspartic coating applications. Repairing spalling concrete and hairline cracks helps make sure the coatings bond properly and seep into the surface effectively. However, the professional installers may recommend replacing the concrete if any of the following forms of damage occur:

Settlement cracks

Settlement cracks almost always require replacement before coatings can be applied. Improper subgrade preparation prior to concrete application is a leading cause of this problem. Also, the ground below may have eroded after a nearby tree was cut down and the roots decomposed or a utility company dug trenches to lay down pipes or lines but failed to compact the soil when they refilled them. Without proper support, some sections of the concrete slab may sink.

Expansion cracks

Long-term exposure to hot temperatures can cause concrete to expand, pushing against an adjacent brick wall, slab, or any hard structure in the way. The expanding force can be enough to cause the concrete to crack, which can be quite extensive and severe. Like settlement cracks, this form of damage needs to be fixed via replacement before the application of garage floor coatings.

Frost Heave Cracks

This form of concrete crack is common in areas with cold climates. When the ground freezes, the slab above it shifts out of place as the soil swells. As the ice begins to thaw, the soil settles back in place, causing the concrete slab to sink. The cycle repeats, resulting in cracked and uneven concrete. Trees with large roots have the same similar effect. In this instance, the affected concrete and subgrade will need to be removed and replaced.
