Limestone versus double brick cavity retaining wall to support slab?

15 days ago

We were considering a limestone retaining wall to support the slab but our builder recommends a brick build up because it is a little cheaper. Our previous house had a limestone retaining wall and we never a had an issue with it aside from very minor crumbling (it was over 60 years old and not too far from the coast). Are there any advantages or disadvantages of limestone compared to brick? We've read that brick readily draws up moisture does limestone do the same? Also, the brick build up would have a concrete footing but I'm not sure about the limestone retaining wall.
