I have a short (4 feet by 10feet) and cracked concrete walkway from my basement door to my backyard. Also, it is uneven in some places. No matter how much I clean it, it gets dirty and weeds and grasses starts growing in its crack. It makes the yard look terrible. I don't have a lot of money to spend on it to get a professional help or even doing it myself. So, what I am looking for is something that I can lay on top of it to cover it up much like a rug but meant for outside. Do they sell anything like that in the market? Any ideas or suggestions will be appreciated. thank you.
