I have a salt water pool in my backyard and I'm not gonna lie, I love the minimal maintenance and complete lack of algae. Sure I have to pour in acid on a regular basis, but beyond that the pool mostly takes care of itself.
Downside is my limestone retaining wall (picture below) is starting to really show some wear. There are some stones that have holes in them all the way through. I'm not concerned about structural integrity as the limestone is just a veneer in front of a concrete/cinderblock but I'm curious what my options are. Wall is about 13years old, so this is nothing that has happened rapidly. However I've only been the owner for the past 2 years. So I'm not sure if anything has been done to mitigate this damage. I know I haven't done anything though.
I'm tempted to just have new limestone put in where stones are worn real bad. There are plenty of places that show no wear though. Then I'll just have to keep doing this every 5-10 years. However I also thought about just replacing the veneer rock with something else or stuccoing the limestone (if that's even possible). It's hard to tell in the pic but this wall is REALLY long. Its about 90ft or so with ~40ft directly in front of the pool. So I'm a little reluctant to throw in the towel on the limestone, but wasn't sure if anybody knew of any options?
Has anybody else had to deal with this kind of premature stone wear from salt and have any ideas?
