Small cracks – Perhaps the simplest and most common type of concrete repair. All concrete cracks during the curing process, and over its lifespan small cracks may form due to the various forces exerted on the concrete. Small cracks are straightforward to repair. You need some standard basic tools – such as a chisel, hammer, trowel, and bucket for example – combined with the right repair materials that you can find at your local supply store. Be sure to fix small concrete cracks as soon as possible. Eventually, water, salts, and debris will enter those cracks. Water is perhaps the worst culprit. When water freezes in the winter the expanding force created by water expanding into ice crystals is greater than the tensile strength of concrete. Water freezing will turn your small cracks into large ones. Vertical wall cracks can be fixed by using an injectable epoxy. Epoxies allow for complete bonding and sealing of vertical cracks without causing further expanding forces on the concrete. Most repairs can be done with minimal labor if there is easy access to the vertical concrete wall.
