Rockery Design with broken stone backfill
Rockery Design with broken stone backfill
(OP)
Re: Thread 255-322322; I'm familiar with FHWA CFL/TD-06-006; I've a contractor that want's to use granite blast rubble for backfill behind an 18ft tall rockery. Very angular but randomly graded (4in to 24in pieces). Any ideas about weight and lateral pressures or potential problems? (I'm always tentative about rockeries because they depend so heavily on the contractor's experience in construction them.)





RE: Rockery Design with broken stone backfill
I would call your guy with the FHWA and talk to him about it. That's a pretty serious wall at 18 feet, and if you're dealing with them, you're probably dealing with roadwork, which means traffic, which means safety. Just sayin'.
