Chipping and pitting on concrete surfaces can be an eyesore and a safety hazard. Fortunately, there are several ways to repair and prevent peeling concrete. Patching with a matching color compound, re-coating with a sealant, and using a 100% epoxy concrete patch with a sand aggregate are all effective methods for repairing chipped concrete. To prevent flaking, it is important to apply a good water sealant to the finished surface.
Concrete chipping is caused by a variety of factors, including the curing process, interstitial contaminants, moisture ingress, alkali-silica reaction, and poor finishing. If the structure is in an area that is accessed by the public or workers, then chipping concrete can be dangerous in terms of falling debris or tripping hazards. Our team is experienced in handling any problem we may encounter in any concrete shelling project. We recommend using a 100% epoxy concrete patch with a sand aggregate for larger areas of pitting and chipping.
Silica sand is mixed with epoxy resin to act as a filler. The HD-110 concrete patch from Legacy Industrial is a good example of this. For smaller areas of chipping, patching with a matching color compound and having your concrete re-coated with a coat are both effective solutions. Mix one part Portland cement Type 1 and one part fine sand by volume.
Add water until the mixture has the consistency of a thick paint, then apply it to wet concrete. As climate changes, concrete expands and causes it to flake, leading to further deterioration. To prevent this from happening, it is important to apply a good water sealant to the finished surface.
