Have your concrete re-coated with an overlay, freeze-thaw cycles, de-icing salts, poor finishing techniques, improper curing, poor concrete mix. Chipping is the peeling or detachment of small particles of cement paste from the portion close to the surface of the finished slab. In most cases, the defect does not affect the life of the slab if left untreated. There are several ways to fix peeling concrete.
First, determine how serious the problem is. If the chips penetrate less than a third of the depth of the concrete, a patch or repair can correct the problems. However, if there are deeper chips or pits, it may be better to completely remove the concrete and pour a new foundation. The facing material is simply spread over the existing and chipped concrete surface to create a fresh and flawless finish.
If you ignore the flaking, it eventually spreads, compromising the integrity of the surface until it can't be repaired, leaving no recourse other than to tear it off and start over. Weakened concrete is more susceptible to cracks and crumbling, and vertical structures, such as walls or columns, can completely collapse if peeling becomes severe. In recent years, complaints of chipping (flaking) of exterior concrete surfaces have been increasing. Descaling occurs in the outer slabs when water trapped in the concrete goes through multiple freezes and thaws.
If you have chipping on the wall of a basement or other vertical concrete surface, the solution can be a bit complicated. Fortunately, peeling can be easy to repair without the need to completely replace all the affected concrete. All concrete can develop cracks and flaking is inevitable, especially in colder climates and as concrete ages. Another key factor to consider is concrete mixing, as excess water content can also lead to chipping.
This is best for large areas with extensive peeling and will rejuvenate the concrete to a like new look. A few small flakes coming off a large concrete surface may not seem like a big problem, but once the flaking starts, it's even easier for more moisture to get into the concrete and the flaking will spread. To fix a concrete wall that is chipping, you must first cut the concrete around the chipped area. One technique that can prevent concrete from flaking is to apply a good water sealant to the finished surface to prevent water from entering the concrete.
Concrete resurfacing systems are designed to cover cracks, chipping and other imperfections with a durable mechanically bonded microcement.
