I'm so glad to have this information about this type of subfloor.
I just moved into a house that has old vinyl tiles attached directly to the concrete floor, and I need to remove them because lots of efflorescence developed between the tiles and the concrete, thus, many of the tiles are warped and coming loose. So I was in the process of deciding what to do about a subfloor when I came across your responses to Katrina's message. The DRIcore subfloor seems like it will be an excellent choice. We have Home Depot stores that sell it here, so I'm looking forward to seeing the product.
If anyone out there has any experience with the DRIcore product, please let us know how you like it.
