Not sure if anyone still checks this forum but I'll try. I had about a 10" slope in my yard over the 16 foot depth of the green. I built up the base with 3/8 traffic bond and compacted with every inch or so of depth. I have a slope off the back of the green which doesn't look too much different than many real putting greens. How will this hold up with turf over it? I know the instructions say to put a border all around, but that obviously doesn't work when you have a slope like this. Even with the slope you see, my green will drop 2-3" from front to back.
