This is my first review of this product but have used it quite a bit in the past. In short order Im a professional with over 30yrs experience. This product seems far superior than hardibacker at about the same cost if you included the screws not to mention the weight difference strata 600ft+ 2 rolls less than 200lbs, 600ft hardi 40+sheets about 1,100lbs. And far less than ditra if you dont need it for waterproof areas and does the same thing with the bonus of using modified thinset for the tile installation which is required with porcelain tile. Do your research I did and I like the results its a bit of a workout to work it into the thinset and you definitely use more thinset overall but also much better open time with the stratamat and no messing with taping the seams either. In short I think its a great product

I started using Strata Mat about 4 months ago and I have been more than happy with the results. I was a big fan of Ditra and then my local supplier and I had a falling out and I found this and boy I am glad I did. Here are a few reasons I prefer this over Ditra.

1. It is 45" wide vs. Ditra's 39.5" (not a major but for me it matters)
2. The hydration vents cause the mortar to be placed into the underlayment much easier. If you have any experience with Ditra, you know that you must trowel over the underlayment at least twice to fill the "ditra-pockets" with mortar. This is because air trapped in the pockets have no where to go but up, creating bubbles in the mortar. Strata Mat has pin holes in each pocket that allow air to escape as it is placed into the underlayment. (This is a major advantage!)
3. You can use any type of mortar. You're not limited to unmod. or Ditra-set
4. Since it is white. You can see chalk lines on it.
