I was going to take the ICPI class in my area, but was notified it was full so I guess I will have to wait til next year. I have installed a few patio's but would like to brush up on some techniques and install procedures to make things go as smooth as possible. Do you guys know where I could get any good DVD's, video's or books that are informative. I feel that the more you learn, the more confident you will be. Thank for your help. Really wish I didn't miss that class.
