What's up guys. I am new to the board and very interested in learning how to hardscape in hopes of eventually incorporating it into my business. I would like to do a little project in front of my house to start out and have been reading up on all of your posts to try to obtain enough knowledge to do so. I have NEVER done any of work of this kind so basically don't have a clue. One of my questions is, what is the sub-base/fabric you are supposed to lay before the bedding sand? Where can you buy that? I also heard it referred to as course aggregate I believe. Keep in mind, I am only 20 and have had no experience in this field so my questions will most likely require a little patience from you veterans. Haha, Thanks.
