Not sure on the type of membrane. I haven't had to do it myself, but it is how the contractor did it on my brother's beach house in Galveston. I would assume that any type of membrane that isn't dissolved by contact cement will suffice. You could probably find a suitable product somewhere on the web. I would think that a thick pond liner would be ideal. The wood decking will do a good job of blocking out virtually all of the UV rays. The nice thing about the system is that you can pull up the wood decking every year or so and rinse the membrane off with a hose to prevent buildup of leaves, dirt, etc.
