Questions & Answers

How do I install the footer stud in relation to this?

Do I drill through this to anchor the footer on top of it? If I lay this flush up to the side of the footer, it'll defeat the purpose and won't allow air underneath it (or water that might wick from the basement walls, also opening up the wood to rot if it gets wet).
Asked by: Jonathan
Hello Jonathan: Non-load bearing walls can be installed directly on top of our product. The installation instructions can be found here: https://www.dmx1step.com/wp-content/uploads/2017/12/DMX-1-Step_InstallationChecklist.pdf. If you do decide to build the walls first then lay our product up to the footer leaving a ¼” gap between our product and the footer allowing vapor moisture to escape. Customer Care DMX

is this to be installed primarily over concrete? Or is over linoleum ok? What is the thickness of the pad?
Asked by: cR
Hello cR: DMX 1-Step has been designed to be installed directly on top of your concrete floor. The dimples are 8mm in height with 1mm of foam on the dimpled (white) side. Please ensure that the floors are level up to 1/8" over 10 feet, prior to installation. Customer Care DMX

Can I build my basement wall on top of this product? The wall will be 2x3 studs covered with drywall.
Asked by: Dave
Interesting that the 1st answer from the DMX customer care says you can install non-load bearing walls on this product (supported by the install instructions on the website); yet, the the rest of you say no way. It is not my intent to pick on anyone, but I'm curious why folks say not to put the walls on top of the DMX product? If you have taken the time to vapor seal your walls and rim joist, running this up to the foundation wall and sealing with foam seams to be the logical step to complete the vapor barrier. The holes drilled through the base plate of the framing should be filled with silicon before driving the tapcon to ensure the punctured DMX is sealed. Help me understand why what I outlined above is incorrect? Thanks in advance.

Do I need the underpayment if I install vinyl floor in the basement?

Asked by: Katrina
After reading tremendous articles about basement. I would suggest you purchase a underlayment. Your basement has a cement floor which is very porous. With that being said the moisture from the soil will breathe through your cement and will create mold if you don't let it breathe and give it space to dry. What the underlayment allows is that moisture to escape and dry underneath your floor. I use this DMX product in my basement. I can't tell you its the best thing yet because I just installed it about a month ago and won't know the long term advantages until about a year a two and really figure it out. But with all the reading I did, this is the route I chose. Good Luck

100 sq. ft. 3.67 ft. x 27 ft. 6 in. Unique Air Gap Underlayment Prevents Mold and Mildew is rated 4.5 out of 5 by 161.
Rated 3 out of 5 by from good product but some drawbacks ordered and put down 1,000 sq. ft. of this when refinishing my basement. Put 10mm luxury vinyl plank right on top of it. Did days of research on floor underlayments; whether I needed one or not, what type - OSB or vapor barriers like this, competitive products, etc. I settled on this because it allows water to run underneath it in case there ever is a leak in the basement, it has the foam attached so there is no clicking noise when walking on it, its a vapor barrier, makes the floor softer to walk on, its very thin profile, and of course its ease of use and transport versus using OSB. While it does virtually everything it claims to do there is one major drawback and one really insulting factor. The drawback is that it comes in 40 foot rolls rolled up really tight. I unrolled it and let it sit for 4 days until it looked like it was as even as it could get but after putting it down, it was still wavy and made laying the floor very difficult as it would bubble up all over the place. This ended up leaving a couple of hollow spots under the floor and trust me I did everything I could to flatten the stuff out, it just wouldn't flatten. I'm sure when the manufacturer uses it and makes claims about it they're taking it right out of production, not after it's been rolled up for a month or two in a 1 square foot box.This brings me to the insult - they make you buy their tape to tape the seams together at $10/ roll with only a hundred feet of tape per roll. I needed 7 rolls of tape. That is ROBBERY for some plastic tape. And I'm sure if you try to use regular box tape ($2/250 ft roll) they will void the warranty. It's a small, crafty way to milk pure profit out of you that damages the experience. Like a car dealer charging you $100 for a gallon of gas to drive the car off the lot.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from Works well, fairly easy to install This underlayment does a decent job of keeping our laminate flooring warm and dry. It’s also very easy to cut to size with either a box cutter or scissors.

Rated 5 out of 5 by from DMX 1-Step = a great choice My wife and I hired a general contractor to finish our unfinshed basement in our newly built home. In order to save money I decided that I would handle the subfloor and floor installation in order to save labour costs and we would leave all the rest (framing, electrical, plumbing, drywall etc) to the pros. We spent a few weeks going back and forth between DriCore and DMX 1-step for our subfloor. After many trips to Home Depot and lots of online research we chose to go with DMX 1-step, and I am so glad we did. Not only is this product the best cost/sq foot in subflooring it is by far the easiest to install! Aside from the easy installation I think the number 1 selling pioint of this product, (aside from all of its great properties) is that there is almost NO WASTE when installing. Every scrap piece of DMX 1-step that I had left over from cuts I was able to use in a differnt area. We had a few tricky angles from the overall design and yet all I needed to install this subfloor was an exacto knife. I installed 12mm laminate flooring on top of the DMX and we could not be happier with the look and feel of our new basement floor. Thanks DMX!!

Walking on it before you get your flooring down is not a problem (it's quite strong). Only complaint is the rolls of tape they sell are WAY too short for the money (less than 40' for $10 + tax!).

Has a small bit of insulating characteristics, and is easy to lay down. In my particular project, it has done exactly what I wanted to do. Great product.

Rated 5 out of 5 by from Great product When I decided to finish my basement, flooring was a tough decision. I ended up putting in eng. hardwood floating floor. When it came to the underlayment I did a ton of research before making this purchase. Honestly this was the only product that covered all my needs. 1. Need to cover cold concrete basement floor in Michigan 2. wanted some R value 3. Didn't want to break the bank 4. Easy install 5. quiet Heres what I found with DMX 1. Got the R-value I was looking for, I installed in the winter and it was amazing how much more comfortable the room was once the underlayment was installed. 2. It cost me 1000 bucks to get the large area covered, but compare that to some of the other products out there and I would have spent 5k on underlayment 3. super easy to install 4. After it was done I was amazed at how quiet the floor was. I read a lot of other reviews with other products that had a click to them when installed on concrete. Bottomline - buy it, you wont be disappointed. Also, look up DMX on youtube they have some great info on the product there.
