For cracks smaller than a quarter of an inch, specialists use concrete seals or a liquid-based concrete crack filler. After using the filler to patch the crack, it may be necessary to paint the surface to mask the new filler.

Epoxy injections are also a common method of repairing cracks. Several companies offer epoxy-based products that can repair anything from structural cracks to hairline cracks. Pour enough dry concrete mix into a 5-gallon bucket to repair cracks and patch damaged areas. If the area to be repaired is not large or deep, a sand mix or a concrete resurfacer that does not contain gravel can be used.

A standard concrete mix containing gravel works best for patching large or deep areas. Experts often note that improper removal of top soil and concrete subgrade can be the cause of some more serious problems. Finally, if necessary, brush the surface of the repair compound using a dry brush to touch the surface. Narrow cracks in the concrete can be filled with an elastomeric masonry crack filler that can be applied with a caulking gun.

Instead of going through the expense of removing the slab and pouring a new one, you can repair and resurface the existing concrete. It is good for reinforced concrete to crack when it is over-expanded a little more than when it is compressed, as the steel reinforcement will help to maintain it, e.g. bridge reinforcement. It is possible that the subgrade has been compacted and the concrete has been subjected to extreme weight which has caused the concrete to sink.

It is therefore a good idea to start the repair by filling the crack with foam to create a base to support the repair material. To improve the strength of the concrete, admixtures can be added to the mix before pouring to make it more flexible and reduce the likelihood of cracking.
