I saw a product on Bob V's show that you may be interested in using. It was a wooden tile, and it looked very attractive. It consisted of wooden strips secured to a plastic support mat that allowed water to drain. I have been trying to learn the name of the product because I was very interested in learning more. I did find a similar product on the Internet, called Kwik dek. Try a search on it using Google, you'll find it no problem.
I'm still looking for the product Bob V used. If anyone can help, I would appreciate it.
