Concrete is often used to repair cracks in foundations and driveways. A concrete patch is good if the earth doesn't continue to move. If the foundation of the building continues to shift, or the driveway flexes, than it is only a matter of time until the crack reappears. However, if concrete is mixed with epoxy, the patch is able to flex with the movement of the foundation.

Step 3

Mix 2 gallons of epoxy as directed by the manufacturer.

Step 4

Combine the epoxy and the concrete mixture with 5 gallons of water. Stir the mixture well with a large stick to ensure that mixture is consistent throughout.
