Service walkways were installed using concrete unit
pavers placed over a double-layer of drainage
mat. Rubber pavers were not selected due to concerns
that they might cup or dish, and would not present a
permanent stable working surface sufficient for moving
heavy equipment, etc. Concrete pavers were found to be
less expensive and have a weight similar to the 3-inch
thick green roof they replace where they are located.
