Ive got quotes from two vendors and i have a couple of questions about the things they told me:

What are the pro's cons of Aluminum walls (esther williams) vs Polymer walls (Ft Wayne Pools)? Isnt it true that Aluminum will dent fairly easily?

Is it true that if i put up a new retaining wall that i have to wait 2 yrs before i can put a pool within 8 feet of it (horizontal backfill distance from wall will be 15' and the wall height will be 6')?

The vendor with the aluminum wall offering told me that they can backfill with dirt whereas polymer walls require rock. Is this true? doesnt sound right to me.

Thanks for any/all help.
