I added 35 yards to my drive way when I built my garage for the boat a couple of years ago. Also used some of that to extend my patio. Did the mesh and rods and it's holding strong. When the guy put it in they had some odd slope in the curve and I couldn't understand why there was a slight slope at the curve but he convinced me to leave it. Its work of art for the water runoff and directs it away from my garage. Very slight but glad he knew what he was doing. Good luck G.
