In addition to some travertine pavers around the pool, my client has expressed an interest for travertine as shown below with either grass or a hardy moss, etc.. between the pavers.
My question is this: What would be the best installation?
I'm pondering dry set, like the pool deck, but need enough depth and width of good soil between them for anything to grow. I really don't want these to be wobbly since traffic will be on this area almost immediately.
My gut tells me to form these 16" x 8" boxes, pour concrete, thinset the travertine & have the full width between them to do any type of planting I desire. Basically a 22' x 22' area so I know it would be labor intensive but would probably hold up the best over the years.
Any takers?
