So what's replaced Ditra.? Well, it did not really get "replaced", it just got left behind by updated technology.
Ditra tile underlayment was EASILY "replaced" by several tile underlayments.
The first one we'll give you insight on is Prova Tile Underlayment.
ProVa Flex is a multi-functional polypropylene membrane used as an underlay for ceramic tiles and natural stone. It acts as an uncoupling membrane on all suitable substrates and as a water vapor pressure equalization membrane against dampness in the substrate. ProVa Flex protects against dampness in the substrate and is ready to tile immediately after installation.
Benefits:
Uncoupling
ProVa Flex is a separation layer between tile and substrate, which prevents stress transfer to the tile surface. If the substrate were to shift or move at all, ProVa Flex is there to bridge cracks that may develop in the substrate from this shifting or movement. In other words, a crack caused by movement in the substrate is now completely neutralized and will not be transferred to the floor covering.
Equalizes Vapor Pressure
Air channels beneath the ProVa Flex remain open to allow any moisture in the substrate to evaporate. Essentially, these air channels are letting things breathe. However, Joint Strip must be used to maintain a continuous barrier.
Polypropylene
Polypropylene is impermeable against building chemicals. The polypropylene properties of the ProVa Flex make it easy to install and allow it to lay flatter than a tile underlayment made of polyethylene.
Workability
ProVa Flex is tough yet pliable. Its ability to bend around corners without breaking or creasing makes installation quite easy. ProVa Flex can be cut with a knife or scissors, and its unique profile design and inter-woven polypropylene netting material works to increase surface area. This makes for a stronger bond between underlay and tile.
Suitable Substrates:
•Concrete
•Concrete Screeds incorporating heating systems
•Wood Based plywood or OSB
•Synthetic flooring and surface coatings
•Gypsum based (anhydrite) screeds
•Bituminous Screed
