Purchased this item to put on cement under laminate flooring. Installer said it would make a difference if someone fell on the floor, it would cushion the fall, and could be the difference in a bruise or a break.

Rated 5.0 out of 5.0 by Russ It's called "1-step" for a reason.
It's fast to install and quiet to walk on. No need for felt underneath. Used it in basement under 3/4" T&G for dance floor and some carpet. I was able to use a biscuit jointer for the OSB edges that weren't T&G so didn't level the concrete. I sealed the underlayment seams with Tyvek tape as instructed. The underlayment was worth every penny.

This product does exactly what it is supposed to. I bought 10 rolls to do all of my basement. Lay this down first on the bare concrete floor and tape all the seems with tuck tape and it will create a vapor barrier for the floor. Then installed 3/4 t&g exterior grade plywood. Then installed my floating floor with another vapour barrier
The product is very sturdy so it will not flatten under the plywood. Installed last year before winter. No problems up to now and everything is nice and solid.

Very easy to install. I used this under tounge and groove subfloor in my basement and then covered it with carpet.

I purchased the DMX after looking at Platon membrane and Dri-Core panels. The DMX product seems to be in between in terms of cost, though considerably cheaper than Dri-Core. I ultimately went with this over the Platon to get the foam layer that provides the insulation value.
This was going down in a basement bed room in a new house that has a completely unfinished basement so far. The product was extremely easy to install. I suspected it would have a tendency to curl since it comes in a roll, but only the inside edge curled a little bit and it quickly relaxed. It is very easy to cut and the 1-Step tape goes on easy too. I bought two rolls of underlayment and two rolls of tape. The sq footage was right on the mark. This room is 192 sq ft and I had just a little bit of leftover. I doubled over the tape so there was a wider swath of type and I used both rolls of tape plus a little bit of house wrap tape I had on hand. I then put 23/32 T&G OSB on top. Even though I am doing a hardwood floor in that room, the adjacent room will be carpet so I didn't want a big transition between the two without the T&G under the hardwood.
Even with just the T&G in place, I notice a huge difference in the floor temperature which is what I was going for.
I would advise caution when walking on the membrane or rolling heavy equipment on it. Even though its floor loading is good once you get a floor on top of it, it can compress and invert the dimples with enough force. Dropping some plywood on top of it while you're working would certainly help.
Now for the framing stage...

I just installed this product on my basement floor. When I purchased it, I was pleased to see that they now attach a role of tape to it for sealing the edges.
Overall, it installed quite easily. I put an excellent, commercial quality Wicander 10+ mm cork laminate directly on top of it and had no difficulties. The floor looks excellent but sounds a little hollow when walking on it. I also have a slate pool table on it and it seems to be able to hold the weight just fine.
I'm hoping this provides a nice insulated, waterproof floor for this room. Fingers crossed.

Rated 5.0 out of 5.0 by HandyMike The BEST way to control moisture and give your floor a softer feel!
I bumped into this product searching the Internet for a way to waterproof my basement floor. I emailed several questions directly to the manufacturer and they responded immediately with details on how to handle each situation. DMX 1 Step is easy to install and as I covered more of the concrete floor I started to notice that musty basement smell could not be detected in the areas I completed. The hardest part for me was drilling into the concrete floor to use the TAPCON screws. Buy a higher quality hammer drill and lots of drill bits. I installed 5/4 x 4 sleepers and then 3/4" OSB glued and screwed over top. The sleepers are installed 24" on center. The floor has the same kind of flex as the main level of the house. My wife loves the way it feels when she walks on the basement floor. The moisture control is allowing us to install hardwood floor in the basement. That is typically a no-no. I'm confident the DMX 1 Step is going to be the key to my finished basement not looking or feeling like a finished basement.
It's a great product!

This is an absolute must have for basements or concrete floors. What I especially liked about it was that I didn't lose a lot of height by installing this in my lower lever on top of concrete.
