A sand mixture or a concrete rectifier can be used, which do not contain gravel, if the area to be repaired is not large or deep. A standard concrete mix containing gravel works best for patching large or deep areas. You can also buy concrete repair putty, epoxy for repairing concrete cracks, concrete repair mixes and latex patching material. For larger cracks, you will need to use a mortar mixture.
Although it seems contradictory, the cracks and holes of the concrete entrance cannot be repaired with normal concrete. Repair of the entrance involves grinding the top of the existing concrete and adding a new upper level of concrete. Repair is the perfect method to treat stubborn stains, small cracks and small holes. Proper preparation of the area is the first essential step when starting any type of concrete repair.
The products you use will only be as good as the conditions below them. Removing any crumbling debris is key, and while there's more than one way to do it, using an electric sprinkler can be a big help.

Concrete Network explains that this is between patching and replacing and can make entries look like new. Very fine surface cracks, sometimes called “cracking”, are an indication that the concrete surface dried up too quickly when it was poured.
Before applying the repaver, blow or sweep away any leaves or debris, then wet the surface to prevent the concrete from drying out too quickly. Because concrete expands and contracts slightly with temperature changes, the sealant needs enough not to separate from the edges of the crack. Although concrete is a durable surface, concrete driveways deteriorate and develop cracks over the years. In general, you will have to thoroughly clean the existing concrete with a high-power pressure washer, and then extend the rectifier with a long-handled spatula.
