Thanks for the question! The wall is 12" thick, the outside wall height ranges from 4" to 9", inside wall height is 6", inside dimension is 10x50', French drains inside, under the surface. The wood bumper is a nice touch, but not necessary, we used color concrete with a trowel finish.

Perfect. Thank you so much.

I have a 12x70 court with trellis's at each end. Any suggestions on securing lighting? I have an electrical outlet at one end, but feel t's too far to string lights all the way across.

I recommend running a cable across. Attach the string lights to the cable.

Good Luck!
