Seems to be a lot of debate on this, I need to raise the slate about 2in so i was planning on using tapcons to attach either 5/8" advantec or 1/2in hardibacker through 1 inch xps into the slab with slate on top, also looking to eliminate condensation so using the xps would work for that too.
Anyone with experience doing this?
Seems like it would work the xps is fully supported by the slab could it flex more then a standard installation with a rafter/ply sub floor?
I know the tapcons are a lot of work but its only about 70 square feet.
Thanks!
