So I'm in the process of remodeling my backyard. One of the things I wanted to do was build a wall similar to the first picture I included (with the stacked stone). The red arrows point at the wall.
I had someone come out and build the small wall (it's 28" high from where the pool already ended (where the the white ends in the pictures below and it's 18 feet long) and will be putting stacked stone on it (real stone, so it's heavy). The stacked stone will go from just above the water level where the red tile ends in the pictures below and cover the whole front and sides of the wall.
My question is, should this small wall have rebar in it? I'm not sure the guy who built it put any reinforcement into the wall and it is a very long wall. Should he have drilled into the part of the pool already there and put rebar into it? (or is that dangerous/could cause leaks in the pool and crack the side) Or is rebar in just the new sections fine? Or does it not need rebar? The wall is obviously not very tall, but my concern is the stacked stone is super heavy and it's all on the front part of the wall, could it topple over without rebar? Should I tear it down and start all over again?
Or am I fine because it's so short? Any help would be greatly appreciated.
I live in the Phoenix metro area in AZ.
