Summary: Learn how to repair a concrete crack, prepare a concrete crack and repair a concrete crack or depression using patching compound.
It is always important to prepare well when repairing damaged concrete. Before you start mixing the solution to use on the cracks, you must consider the best way of preparing the area to be worked on. Cracks or holes in concrete paths or driveways can either be holes that need filling, or depressions that need to be correctly supported underneath to prevent further depressions in future.
If the subsurface is not as dense in one area as it is in another, this will be the cause of a depression in the concrete. This needs to be recognised and dealt with by filling in the weaker patches of subsurface with strengthening material to avoid the same problem occurring again.
