Concrete or Vinyl Linoleum For SubFloor?

[Rostov Froisen]

My MSI Everlife Smithcliffs Hybrid Flooring was supposed to be installed on the concrete floor, however, when the installers pulled up the carpet, they discovered 1/8" thick 12" x 12" vinyl linoleum tiles under the carpet and on top of the concrete. They decided to leave the linoleum, apply a thinset type product in different areas, then install the laminate on top. Is this method better than removing the vinyl tiles than leveling the concrete??? Does it act as a moisture barrier? Help.

If the hybrid floor is a floating floor It should be no problem to leave the tiles underneath, and yes it can work as somewhat of a moisture barrier and also moisture detection. if you have a serious moisture issue the old tiles would be popping and/or loose.

If the new floor is getting glued down then I’d suggest removing the old tiles.
