awesome explanation and animation, thank you sir!
Thanks for putting this together
💥💥 Nice video. I just rebuilt 30% of a basement for a customer in the front of the house that I originally built over 20 years ago. She had a rare storm condition that flooded into the front half of the basement where the slab was slightly lower than her sump pump pit in the back of the house and had a french drain that I let my plastic sheeting tuck into that I hung behind all of the walls. The water was over 1/2” deep in that area and the mold remediation co ripped up all of the carpeting in that area and removed insulation and rock 24” up from the floor and aired everything out for 3 days. With the subfloor system that you are showing here any water that comes in and sits on the slab and puddles will never dry out under it and all of that flooring would have to be ripped up because the mold would grow like crazy otherwise. She only had to replace carpeting and padding in a small section 🤟🏼
This is Absolutely great, most informative video I've seen on covering concrete floors! Thank you so much!
Glad it was helpful!
By far the best video I have seen after searching for ages on what to do with my basement. 👏👏 Very detailed, yet precise and gives you all the important pointers you need! Well done Sir!
Glad it was helpful!
except for the outlandish cost of the in floor resistive heating.
This video is a lifesaver, thank you
I liked your video very much! You provided very important information very clearly and in detail. Thank you!
Glad it was helpful!
Keep in mind that stair risers need to be uniform; within 3/8" in height of each other (max.)
So a thick flooring system could be a problem with the lowest stair riser.
Great Video! I had a question on LVP, in my current basement, the previous owner installed adhesive tile directly to the concrete floor. Would I be fine with installing LVP directly over the level floor (LVP I am looking at has underlayment included on planks)? Thank you again!
Great explanations.
Good video !
Thank you sir.
Thanks for a great video. My 60s basement has a slight grade to the basement drain, about 2 inches over 20' so yes a flexible lvp is what I'm looking at. I'm using dmx step 2 as an underlayment. Do you have an opinion on dmx step 2?
Ty
This was very helpful. From an anti-mold standpoint, does the concrete need to be sealed before placing subflooring? Or is the subflooring sufficient on its own? I'm especially looking at the Detra-heat system.
Bailey Line Road. Answer please
Don’t seal the concrete, it needs to allow water to reabsorb when it gets wet
How do you feel about stained concrete floors?
Decent presentation
Thanks for these great
tips
Glad you like them!
I have the sub flooring. Its useless when you have a pipe break / leak. The water gets between the floor planks and the plywood subfloor. I had a ton of mold there as well as warped wood. I've since removed and trashed the sub flooring. I'll find something thats not wood = lets mold grow. Perhaps just a vynyl plank over a vapor barrier.
Edit. I've gone with the One Step. Though that's not without its draw backs as well.
so I think the sub flooring is to help with moisture and airflow correct? nothing will be useful during a flood like a pipe break.
how can I have the in heat floor in option 3 under LVF floor?
Great video

Wish I had a basement to finish.. mine is an underhouse space with 0mm to spare for legal height of a laundry only. With non structural blocks of concrete which have damp coming up on the joints when raining.
Dricore can be very expensive any other alternatives???
THANKS, MY QUESTION IS WHAT IF THE BASEMENT FLOOR IS TILE?
What about in a house that is 60+ years old with no moisture barrier under the concrete floor..?
I installed carpet for over 20 years, chances to find moisture under basement carpet pad are about 1/200. I don't think moisture barrier is very necessary unless there is visible moisture on concrete. A very effective option for carpet is to get moisture barrier carpet pad. Hope it helps
I have one right now. It's exactly this problem
Climate zone is a big factor. Here in Boston we have hot, humid summers followed by frigid cold winters. It’s a breeding ground for moisture, and isn’t always visible.
Mine was moldy when we pulled it up and we have two dehumidifiers... I didn't have a subfloor though I have never heard of that.
Hi, im.planning on laying wood planks over cement basement floor. I have lifted up tiles that were on the floor. I found small areas of condensation and mold beneath the tiles.
I want to cover the concrete floor with the wooden planks. I plan on using liquid glue because i dont have a power nail gun to run cement nails or screws into the cement.
My question is can i put a liquid moisture barrier on the cement floor to keep the moisture from rising to the surface of the floor ?
How safe would i be laying down the wood planks on the floor after the barrier is applied ?
Thank you in advance.
I think your correct, do you know how many homeowners collect on fire claims, why do they carry fire insurance?
Basement floors HAVE to breathe. If you have a shallow water table and you seal it, you will inevitably get hydraulic lifting. This is why a permeable paint with a dehumidifier is the way to go. Sealing it will surely cause problems.
Looking for some advice. Your video is awesome taught me alot. I'm planning on putting a sub floor in a 1940s house. The floor dips up and did but the ol lady doesn't want to use floor leveling on it due to the cost. Do you have any advice? I want to install down then plywood then flooring but not sure what the best option is. That's why I'm asking for some advice
Dips up? If it's small spot then grind it but really only option is leveling with self level concrete
@@JJ-pf7qo there are high spots in the floor don't want to grind it due to the tile is asbestos tile. I want to cover the whole floor and not have to worry about it ever again.
Once the Exterior walls are waterproofed. How would you finish the inside of the basement to make it 'livable' and put hardwood floor on it? is this possible if the Slab is damp? Not leaky with water but Damp.
What if my basement is tiled?
How about cracks on the basement floor and its control joints? I just removed the carpet and found several cracks, now idk what to do first.
What about liquid membrane moisture barrier then glue down vinyl planks? Is it true if you paint on liquid membrane moisture barrier that the moisture will now leave via the walls instead of coming up via the concrete slab so you will now have moisture problem in your brick house walls?
How about eco cork
My house is 130 years old without a vapour barrier under the basement floor. Before I install a sub floor, should the concrete be sealed and waterproofed?
A skim coat will seal it and waterproof it. I would recommend this course of action also to repair and level your original basement floor
I don’t like carpeting at all but it’s cheaper. I have old asbestos tiles to go over, does this need a subfloor over it? I got a quote for lvp and it was about 7k
I purchased a bunch of bundles of vinyl plank with a bonded plastic layer on the bottom. All this is for the basement. I understand that the manufacturer does Not recommend putting another layer down,underneath. The warranty would be void. What’s your opinion?
Good Morning! The issue with basement floors is that they're cool in temperature because of their contact with the earth underneath. And it's this coolness that's the source of potential condensation. The addition of a subfloor layer underneath your vinyl would provide enough insulation value to prevent condensation caused by the concrete underneath. My guess is that the manufacturer would have no problem honouring their warranty because installing vinyl over subfloor tiles is no different than installing vinyl over a wooden, above-ground subfloor. The situations are identical. I'd contact the manufacturer and see what they say in the case of a basement. They have no logical reason to opposed the use of a subfloor, so I expect you'll be fine. Please let me know how you make out. Bye for now, Steve
i want to ask a question but looks like you don't reply to viewer comments :( my fatherinlaw put tile on his basement with no subfloor and there is condensation...do we have to remove alll the tile or can we put subfloor ontop of the tile and then laminent?
remove it
So why doesn't a vapor barrier under the carpet or a vapor barrier pad not work? Has insulation and ability to stop moisture
Not sure I have ever seen a new construction with a basement or a slab on grade house that used these panels
A subfloor is not required with most LVP
Laminate is somewhat inorganic?
It's wood chips with a laminated top lol.
Be nice if the luxury vinyl plank was thicker and flexible and had strong joints.
Strange question: Does the LVP float in water, or is it denser than water? The reason I ask is my basement has had standing water in it once in the 20+ years I've owned it. This looks like it would be exactly what I'm looking for, but want to make sure it wouldn't want to float if it did get a couple of inches of water in it again.
Sink
@@mikerak985 Thank you Mike. I assumed it was dense enough, but TY of the confirmation.
We had LVP and a water leak. Even with dehumidifiers and heaters going we could not get the moisture out from between/under and the LVP. Had to take it all up. Back to bare concrete floors.
We also had ceramic tile floor and water can get between the tile and concrete floor.
Basements suck! That’s just my experience.
What about sealing the concrete first
How do you seal the concrete in the basement?
@@hhova29
I’ve heard about an epoxy seal specifically meant for basement floors. I’m looking for more information on that myself.
Any opinion on polished/stained concrete?
Or perhaps epoxy coating?
No mention of the problem of moisture coming through the porous concrete?
Kind of inevitable unless it’s a custom build
What if your concrete pad has a vapor
Barrier and insulation under it?
Check the channel home RenoVision
He addresses that very situation with only insulation board and subfloor
What about simply smoothing and sealing the concrete floor with an acrylic seal?
That stops water coming through the concrete, but not condensation which is water vapor already in the air in the basement.
Dehumidifiers and the stuff in the video helps with that
You're also going to degrade the concrete over time by trapping moisture where you're sealing. It needs a chance to dry into the house.
A flooring company did my whole basement with vinyl plank and some sort of leveling compound. My problem is efflorescence has now cracked through the leveling compound and warped the vinyl plank. Should they have done a sub floor or moisture barrier underneath before using leveling compound?
They should have used an underlayment that allows for airflow under the plank so it can dry itself.
They should have told you to seal the concrete floor first. Bostik MVP
What are the subfloor panels with the dimples called and where can you buy them?
DRIcore; Lowes in the US
Subfloor down before standing up walls? Or put walls down with pressure treated base plates and that build subfloors in each room?
I prefer to build my walls on the subfloor
ruclips.net/video/v9-VKJ7to50/видео.html
Yeah I don't know whats going on.. going to anchor your bottom plates into these semi lose panels? Probably could work but I would rather ramset pressure treated bottom plate with a gasket to the concrete
I did 2x4 perimeter sill. Then I framed my walls on that and nailed up to the joists. I hung my drywall using a 2x4 spacer so the drywall is only on the framed wall, not on the sill. Then I filled in with subfloor and T&G plywood with tapcons.
Dricore 2x2 panels (be it plastic or 1/8" foam) are both terrible. Any moisture will be wicked up by the osb, and in any heavy cases, the plastic glued to the bottom will actually poole moisture in the divets holding the panel up. Mold growth then becomes excessive, and it will happen within a year or two unless your basement slab is completely void of any water traversal.
Thank you 🙏

What’s the better option?
Plain dimple Matt and use a more robust thicker lvp
The answer is to seal the concrete slab and done! No more pesky mustiness.
After buying our home we noticed that a sump pump was installed for the front of the house and not the back and since we have a finish basement we have water coming in through the back and wetting our rug floors , I would like to install the dimpled subfloor but I’m worried that I’m going to have to raise the base board heaters and that’s going to cost more when hiring an electrician. Does any one have any ideas on how I can get this done with out having to raise the baseboard heaters ?
even if you had to raise them, you would be able.to do it without an electrician.. turn the power off, unscrew them, and raise them.. if the wires are that tight, they're already wrong..
that said, fixing the water intrusion is more important than fixing the floor .. you can't just hide the problem.. fix it right first so a heavy rain doesn't ruin your new floor.. many times it's as easy as adding a downspout extension or cleaning a clogged gutter .. good luck !!
My contractor was supposed to put radiant floor heating in the slab portion of the house any didn't and I don't think he even put any of this material in. I wanted radiant floor heating because I'm disabled. That isn't the worst thing that he did. There's a long horrible list. It's hard when you're disabled to make things right for yourself when other people don't do what they're supposed to. And I didn't know what to look for I thought I did but I did not. And everybody was telling me he was a great guy even though I was telling everyone all the things are going wrong. It made me feel like I've crazy snot now I have a house is not finishing work he did is falling apart. So where is the list of the contractors that won't leave you in a mess like I am? I am the United States.
All you do is paint a liquid vapor barrier on the concrete and lay your carpet, will be fine for 15 years. I do this all day long. LVT is 5x the cost of carpet.
Humidifier
This video makes me want to only polish the concrete floors.
carpet is by far the worst option for basement floors. Too many i've seen with serious mold/mildew issues and moisture-related problems. Carpet harbors that moisture i would always recommend a floating floor option. Laminate worked great in my previous home but to me vinyl is the way to go for basement floor finishes.
Yes, I agree completely. Sometimes carpet in basements is not an issue, bu many times it is. I also agree with your take on luxury vinyl flooring, both plank and tile versions. Vinyl is completely free from organics, and it's flexible so it can easily handle less-than-flat concrete floors.

Yep avoid carpet on basement floors !
Does cushioned sheet vinyl need a subfloor also?
21 like you 👍👍👈🌹
People, just use an average vinyl plank and use a 3 mil plastic underlayment and you are done.
Given the grading of basement floor. Self leveler is easy to pour and then agreed foam and flooring. Who cares if the self leveling cracks,the foam will cover
No polished sealed concrete??🤦♂️🤦♂️
I was done when you said luxury vinyl vinyl flooring being the cheapest you can get
Not only that but it usually has lifetime
Wait a minute. He lauds the flexibility of LVP and then goes right into telling us to put down a rigid subfloor that needs to be leveled. Did I hear that wrong?
For everyone scared of the word "luxury", the plank can be had for 2/sq ft. Or less.
Luxury vinyl is an oxymoron lol
Unfortunately, unless you build or buy new, yours moving into a house thats already finished. And the only fix is to rip it all out and start from scratch, which costs tens of thousands of dollars Our house is 14 years old with carpet in the basement, and we dont seem to have any mold or musty issues. But I have no idea whats below it either
Same with me, I have had carpet in a basement bedroom for 10 years and it has no musty smell. We remodeled the room in an old house which had no vapor barrier or insulation in the slab. I did upgrade to a more water impervious pad but not a problem at all with smell and we even pulled up some of it at one point for another repair and no mold/mildew.
Really we are probably going to replace it for just the amount of wear we put on it. And it doesn't cost much to replace. So maybe in 30-40 years it might get musty but i would never keep carpet that long.
I am sure these panels have a situation in which they are good but not this blanket always use advice.
If only they built basements in a way where they never cracked 😂
im 2 mins in and what he said is not correct. you never need a subfloor you only need a good vapor barrier thats all. you can also seal the concrete itself.
I had this playing at 1.75 speed and still the guy was sounding too slow
Anyone who wants to walk around barefoot or have a home theater in their basement is gonna do carpeting, the dismissive “I don’t like carpeting anywhere in a house”, 🙄
this video is just wrong
Take a look at WarmlyYours, an American company that offer some of the best in floor heating systems.
