Surface Deterioration Repairs
Surface Deterioration
Much like the asphalt raveling or other surface deteriorations, concrete surface deterioration includes the flaking away of the concrete surface and the general wear of the surface. As the concrete surface binder starts to wear away, the aging and roughness of the surface increases; eventually, aggregate particles become loose. After severe surface deterioration takes place, larger aggregate particles are lost and pitting extends to significant depth, jeopardizing the concrete base or subgrade.
Remedy
Before significant deterioration leads to pitting and other more serious issues, concrete overlays are possible with emerging products that provide an abrasion-resistant surface for the concrete. With both traditional and emerging remedies, concrete cracks are sealed with poly-urethane or epoxy concrete crack sealant before other overlaying methods. Overlay depths and material strengths depend greatly on the concrete use. If pitting and concrete cracks that accompany deterioration have developed with prevalence, concrete patching (removal and replacement) may be necessary.
