Will be setting marble tiles over radiant heat slabs that show some cracking. Hearing that there are several products (membranes) that are designed to stop the cracks from transferring to tiles. Any thoughts on which ones are the best?
A few areas will be set over 1 1/2 gypcrete (radiant) over plywood sub. Use the same product here?
I’ll take all the suggestions I can get as some products may not be available in my area.
Thanks

I am not all all worried about the vapor and moisture issues that Ditra adresses (it's not an issue in my case), or the benifit of being able to tile soon after the slabs are poured (these slabs are 3 years old. I just need a product that assists in the prevention of cracks transferring. The Ditra product looks great but will I be spending extra money on something when maybe I only need a product (membrane) that addresses cracks only and might be less expensive?
Thanks!
Kind of a reply to myself:
I guess the cost of the actual material is not that much, rather the expense here is the additional time it takes to morter a membrane down prior to setting the tile. Any membrane will take this time so I might as well buy the best stuff, yes?
