Cracks – This includes surface cracks, crazing, and hairline cracks. There are two types of cracks: working and non-working. Once resurfaced and sealed, non-working cracks do not recur. As for working cracks, the addition of a custom scoreline or expansion joint can help provide enough room for the slab to move without causing a new crack.
Holes – Small holes, pits, or craters can be covered and masked off with an overlay. There are many ways to deal with holes, depending on how deep they are, before an overlay or coating can be applied. Grinding can be done on concrete floors with shallow holes or scaling. Deeper holes need to be filled first before it is topped off with an overlay. Effective concrete repair products for this type of issue are stamped concrete overlay, epoxy, polyurea polyaspartic, and acrylic cement coating.
Discoloration – Concrete has the tendency to discolor due to its high porosity. In case of a discoloration or stain, a coating of acid or water-based stain would help. Not only will the discolored area be covered, the whole surface would look absolutely eye-catching.
