Schluter Ditra Uncoupling and Waterproofing Membrane

An uncoupling membrane provides installers with a number of benefits that overcome environmental challenges. It's primary feature as an uncoupling membrane helps to neutralize stress caused by movement in the substrate. This feature enhances the strength and durability of the tile installation.



  • Uncoupling - Add strength and durability by neutralizing in-plane movement
  • Waterproofing - Polyethylene composition protects from moisture penetration
  • Vapor Management - Channels on the bottom provides a route for moisture and vapor to escape the substrate
  • 1/8" (3 mm) thick, which minimizes tile assembly thickness and reduces transitions to lower surface coverings (e.g. carpet, engineered wood, and vinyl)
  • DITRA allows for ceramic tile application over single-layer plywood or OSB sub floors on joists spaced up to 19.2" (488 mm)

Questions & Answers

Hi, I’m wondering if this is the newest version? I am just finding out on the Schluter website they have made an update on the original. Been using Ditra for so long, I hope they don’t change it too much.

This is the most recent version. According to Schluter the only change made was a slight shape change. The updated Ditra Schluter Uncoupling Membrane Waterproofing still has all the same benefits as the original membrane but the shape change makes the installation a little easier and more efficient.
