Just a quick question. (ok... the question is quick but the description is long... :P
My last above ground install (many years ago) used road-mix / screenings as the pool base and just a "skim layer of sand". Turned out to be like a slab of concrete and a great base.
I've seen online and (I think a few on various forums) that a few have used a road mix as well. Right now I've got appx 6" of screenings. Everything is level and it's like a perfect "slab" after 2 passes with the plate compactor. (I could park a car on this thing and not leave a mark).
I'll be using the Galdon Pool Cove and the ARMOR SHIELD (both just arrived). Since I have a butress free pool, I 've got the corrugated steel and metal straps for the supports under the bottom of the pool.
My neighbors pool also used screenings (we have very rocky / solid rock since we are on a big hill). On the corrugated metal, the "grooves" were filled in with screenings and then a layer of sand on top of that for the actual pool base. (He has no Happy bottom,. Gorilla Pad etc - everything has been fine with his install).
I've been told to just use the screenings for the pool base and go right over with the ARMOR SHIELD since the screenings are so darn smooth. Still . . . I'm thinking that I still need at least a "bit of masons sand" just to make everything nice and super-smooth (Even though our old pool literally just had the liner sitting on top of screenings for 10 years with no negative effects).
Can I get some opinions before I do my final prep?? Right now, I'm thrilled with the level and the smooth surface. I'm thinking that at thin layer of sand would make things extra smooth.
Any thoughts would be a big help.
