Right now we have a wood patio, but it just does not go. We are going to pull it up and we want to pour down cement. Has anyone ever done this and any tips or tricks that you may recommend. We will be doing this over dirt. I told my wife we should do bricks, but she is concerned about stuff growing up in between. I told her we could use some caulk in between the bricks to prevent this. The bricks would be a lot easier to do, except around the other areas to where the concrete will match up to the existing patios.
