We have built plenty of walls similar to this in the past without issue. Lots of Grid, Lots of Base and lots of prayers, haha. The plan for these walls is poured concrete walls with a natural stone veneer.
Also in case something is thinking it I would love to see a water feature from the walls into the pool but the client doesn't like the sound of them so that's out.
Truck, Mower, Trimmer, Blower.....same as everyone else.
