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

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
Hello Katrina: DMX 1-Step has been designed for laminate and engineered hardwood with a minimum thickness of 8mm. We do not recommend the installation of vinyl plank flooring directly on top of DMX 1-Step. Customer Care DMX

DMX 1-STEP 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 199.
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 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.

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!!

I wanted something to lift the carpet off the cement floor so it wouldn't get damp and yecky. Tape was included and it was easy to cut with scissors. considering getting more for another spot in the basement....just a bit pricy.
