Using a pointing trowel, push concrete patch into the holes and/or "build" missing segments of concrete, and then smooth the concrete patch out. Remember, even if the edges aren't perfect, repairing the cracks before they get out of hand is the way to go. If you're working at the edge of a swimming pool, hold the container of concrete repair below the area you're working on, to catch any concrete patch you slop around before it falls in the pool.
After the patch has cured use concrete sealer to prevent water from entering the patch and damaging the same spot again. Sealing concrete can prevent damage from occurring as quickly.
