Hi there, I'm in a dilemma trying to figure out if possible and what exactly do I need to set a fire pit over the existing concrete patio floor in my backyard. I know that fire and concrete don't go well together. I've read that I would need to lay down a layer of fire bricks, some others say I just cannot do it. But would like to get your advice and suggestions. How can I complete this project. I bought the fire out kit from home depot, which included the fire pit stone, a steel ring and sand. What do you suggest? I am a young single woman, so I'll be doing this by myself. Please help!!! Thanks a lot!
