I have been spending a lot of time in home improvement stores lately. While looking around, I have seen the cement patchwork kits you can use for concrete flatwork. I always thought working with cement was better left to the professionals, but the associates at the home improvement stores assure me that I could fix the cracks in the sidewalk leading to our front door.
I am going to take a free concrete flatwork class next weekend and see if I think I can complete the job. If I do it myself, I will save a good amount of money.
