When using DMX airflow underlayment on a basement cement floor, can carpet be installed over it or do I need foam underlayment as well?

Asked by: Truus
The DMX will protect the carpet from a moisture point of view, so it will work fine, but I still recommend a foam layer. It comes down to comfort. If you are installing a dense berber carpet, you will get a stiff feeling and slight noise when you walk on it. I wouldn't recommend a carpet with high pile. The foam for carpet provides the squishy softness for the carpet as well as noise reduction.

I’m floorings basement in an old house that gets regular dampness. It’ll be a storage area mainly. Can I put plywood directly on top of dmx

Asked by: Thomas 888
Yes you can.  That’s how I used it too, no issues. Just make sure you install it correctly, using the tape. You’ll need to screw the plywood too.

Can wall framing be on top of the dmx air flow?  Or the the the dmx air flow needs to install around the wall’s framing?

Asked by: Doug67
Simple answer is no. You want to frame your walls to the floor every time and then run the DMX up to the bottom plate after you finish framing.  You can seal the gaps with a subfloor vapour tape that comes with it but you will need more then is provided.

Can you install Interlocking Heritage Mill Cork Flooring on DMX Airflow. Specifically 13/32 thick, 11-5/8 inch wide or 5-1/2 inch wide cork floor planks.

Asked by: MJM66
Hello: DMX Airflow has been designed for laminate, engineered hardwood and WPC and SPC vinyl plank flooring. We have not tested our underlayment with this type of flooring, as cork is typically used as an underlayment. At the moment, we are unable to provide an answer to your question. Customer Care DMX

Flooring Underlaying Membrane - Polymer - 100 sq. ft. is rated 3.8 out of 5 by 5.
Rated 4 out of 5 by from Excellent product, awfull tape I used it for the entire basement with compatible SPC luxury vinyl. Floors are nice, warmish, no smell. BUT. There is a small leakage through the tape. It would be a disaster for laminate. The scotch that they supplied with the product is awflul, dollar store quality. Use blue technical tape and that will be excellent

Rated 5 out of 5 by from Easy Installation / Good Value This review is based on installation of DMX airflow one year ago. I installed DMX in my basement underneath laminate. We were concerned about potential issues with the laminate getting wet and wanted something which was a little higher quality than the base subfloor underlayments and that was easy to install. So far, there haven't been any noticeable water issues. There is no smell and no visible warping of the laminate. The feel on the foot is decent. The floor is warmer with DMX and laminate than without. There is also no clicking sound which i know is a problem with the underlayments that are not padded on the bottom. It does feel a little more soft than having OSB underneath but it's barely noticeable and you get used to it quickly. Something to consider is that if your basement floor is not level, you will need to find a leveling solution prior to installation. I have a few spots that are a bit off and you can feel them when walking on those areas. These areas are only a couple of square feet in a light traffic area in a giant basement so I don't care and technically I should have fixed it before installation. Installation is easy - you roll it out, cut at the wall with an exacto knife, and tape the seams. The alternative is a base underlayment with OSB or the expensive interlocking squares - both requiring more complicated cuts to be made. Also the alternatives are not waterproof and you won't be able to reuse them if soaked. This product may seem expensive but just wait until it goes on sale. Also, you can save money as installation is doable for someone with little experience like myself. Good luck!

Rated 1 out of 5 by from Only good if your installing Carpet! Purchased DMX subfloor (9 rolls) as I wanted to install LVP (luxury vinyl plank) in my basement. Basement slab is perfectly level. I purchased the LVP from a local flooring company, the product is high quality and cost me $4k. Unfortunately after the installation I noticed that almost every butt joint would click and come apart. I have installed a lot of flooring, myself and my crew installed the flooring correctly. The underlayment has too much play for a drop and lock LVP. I would also not recommend a floating engineered hardwood as there is too much risk. If your going to install carpet you would be fine with this product, otherwise be warned. Spend the extra $1/ft2 and buy an actual subfloor or install 3/4" OSB over top of foundation drainage board, same result but more economical. I highly regret installing this product, especially after all of the effort and money it took to finish my basement. Unfortunately if you remove LVP after installation the joints get damaged as the product is thin. So essentially I am stuck with butt joints that don't lock together and click because I don't want to waste another $2k-$4k damaging the LVP to pull it up. I also should note this is the very first review I have ever written, I felt compelled to warn people of my mistake.
