Yes, uneven concrete can usually be repaired and brought back to its former brilliance. Other methods of restoration are required if the concrete has experienced too much damage in the form of severe fractures, dramatic settling, or missing pieces. Lifting and stabilizing concrete that isn’t excessively fractured or uneven is possible, but slabs that are beyond repair may need to be totally removed and repoured. Because this may be costly and time-consuming, it is better to address possible issues as soon as they arise.
