Easy to cut and install. Saved money by not needing to buy OSB. Slight help to basement-to-ceiling height.

Overall good - beware if matching old roll
I have used this product many times in basement applications. The issue is, they changed the design at some point to be thinner and more dimpled. Before the dimples were dime sized for example and now they are maybe half the size with more of them. The overall height of the sheet is half that of the previous design. Beware if you have left overs of the old design that you think you’ll just go out and buy more and all will be good. Not the case. I laid a roll I previously had, then went to go buy more. There was a height difference that you could not ignore when putting a flooring material on top. To solve this, I had to double up the sheet of the new stuff in order to achieve the same height of the older roll I had. A pain because now the same section cost me double since I had to lay two layers of it. I’m no engineer so Im just assuming the new version has the same properties as the old one as far as moisture and temperature barrier abilities. Not going to lie, it was super annoying to have to buy double what I needed all because the product did a major change at some point. If you are just starting out fresh, you’ll have no issues and you’ll be none the wiser. Overall good, inexpensive way to cover basement floors for flooring install applications.

Used this DMX underpayment on concrete slab with engendered hardwood in my house. Floating floor installation just on top of this thing. And it’s great! Feels pretty solid with Evergreen planks that I had (I think they are 3/4 inch).

Cuts easy. The flooring sits nice and flat. My only complaint is the floor is not quite. The white side with the foam like backing that sits on the subfloor seems to slightly stick to the subfloor. Have you ever walked on a floor that spilled soda or juice on the floor, and it sticks to your shoes? That is what it sounds like. I'm not sure I would use this product again.

Top notch product.
Top notch product; ive worked with all types of underlay from cotton to plastic; this product performs as advertised; easy to handle; tougher quality than i expected; i used directly on concrete and put eng hdwood on top.... install was easy and flooring continued performance is great due in major part to this underlay.

Great product.
Very easy to install - works great with the vinyl flooring we put down. Comfortable and provides a barrier between the concrete and the flooring.

We installed this under an LVP vinyl plank floor. I like the way the product installs, and the shape/texture of the product, with it's air spaces. We just installed it last week, so I don't have any long term experience, but if it lives up to it's 10K psf crush resistance, and my vinyl floor doesn't separate, then I will give it 10 stars!

Excellent quality, feels very sturdy yet easy to cut and shape to what I needed. Size chart was dead on, said I'd need 2 rolls with some leftover, and that's exactly what happened. I used in a basement area on top of unsealed concrete base where there is concern of mild moisture build up. The air gap and raised nature of this make me feel confident any moisture that doe occur will not effect the actual flooring, but rather dry on it' own through the channels underneath.

I put this over a basement floor, it has made the floor a little more comfortable. If I had more room I would have built up a subfloor with insulation. This was a nice solution.

        I did not install this product, I hired a professional to do it. The one thing I can say is that the fact that it comes with more than enough tape -you don't need to buy anything else. My main motive for using this product is for it's ability to vent moisture. As I used it for the concrete slab in our walk-out basement and I knew the slab probably wasn't poured over a moisture barrier (1981) so this became a prudent choice.

          Not same as original product. Advertised as 8mm thick, but is not. Only 4mm thick. Not comparable with old product. Already had old product down and was finishing project. Resulted in a 4 mm step down to deal with.

          Hello Chad:

          DMX 1-Step Underlayment (original) had 8mm dimples. This underlayment has been discontinued and replaced with DMX 1-Step 2.0 with 4mm dimples.

          The new DMX 1-Step 2.0 provides a higher dimple density and a lower dimpled profile, increasing the compressive strength to 12,000 lbs per square foot. These modifications ensure that the product is more rigid and therefore suitable for (click) vinyl plank flooring (≥5mm), as well as laminate and engineered hardwood.

          DMX 1-Step Underlayment (original) has been discontinued approx. 2 years ago, and DMX 1-Step 2.0 has been its replacement ever since then.
