My wife and I were watching episode #3025 of TOH that showed using recylced concrete to create a new walk way. We are purchasing a new home and my wife and I would like to give this a try. It was part 9 of 10 of the los angeles project that aired on March 26,2011. If anyone could tells us where to find the episode to watch or a How to do step by step process would be great. Thanks for you help
