I am putting together an estimate for a residential customer who wants to clear a bunch of scrub brush and weeds from his pool area and install a nice looking loose stone bed. the immediate pool surround is a crab orchard patio. I have two questions: Anyone have a suggestion on a nice quality "river rock" type of smooth stone that will go with the crab orchard? (if not I am going w/ a 3/4" pea gravel) and also, it was suggested by a friend that after clearing the area I should put a layer of RCA and compact it with a plate tamper prior to rolling out the landscape fabric. do you think this is overkill?
