Either way the content is excellent thanks Jeff.

Hey Jeff, Thank you for all of your videos. As a first time home owner on a strict budget, I just finished remodelling my pantry. Which involved framing a wall. Drywalling. Taping. Mudding. Repairing all the other walls. Plastering other walls. Tiling and grouting. All of this I learned from your videos. Thank you so much. And I look forward to more videos and more projects to do around the house.

This is great. Jeff is Gold. I used Jeff's dimpled membrane as a base, then the durofoam 3/4" rigid foam , then 1 x 4 strapping (full perimetre and 2' x 8' sections) then 5/8" OSB. all as my base. then built my walls on top of the subfloor. ALso insulted the concrete walls with 1" durofoam. glued and taped. all thanks to Jeff.

Nice to see this method is catching on.. I tried this 17yrs ago, but i went 1-1/2 foam lol. Pro tip- TASK has the most durable drill bits (i got them at Homehardware) purchase the more expensive one.. They outperformed even the Bosch bits

[@jbaccanalia]

Handy tip,, drop a piece of weed wacker line in the whole before the screw. It guarantees a snug connection and you can use epoxy screws instead of tapcons. I've done this job before and can verify it works. Don't frame under the floor. It'll just complicate things. Definately floor level first if you need to.

[@A65impalass]

When you said to screw down as you go or you'll end up with gaps...........only a man with personal experience would mention that lol. I know I personally can vouch for screwing up a bunch in my remodels.....but that's what teaches us right? Then we take what we did wrong and pass it along to help others. I love your videos and look forward to seeing them.

Great video Jeff. To me it really drives home regional differences in building requirements. In BC (Nanaimo) my basement only required a click lock vinyl designed to go direct onto concrete. In this area, the concrete is thermally stable year round within 2⁰C.

[@stevecloyes171]

Damn just when I need it! I need to finnish the basement since we're having another kid and i was in the process of researching suitable insulation for the subfloor and here it is. Im planning on putting a DMX down for water control and a moisture barrier, insulation and the osb, this is by far the cheapest option. im only doing half the basement for now and start to finish it should only cost about 4k, im pretty happy with that. Thx for the video.

[@HomeRenoVisionDIY]

Cheers and congrats on the addition to the family!

[@HighlandCowWoodworking]

Thanks

[@MitchOfCanada]

opted with no thermal break at all, have wood stove in basement so the concrete heats up and holds the heat, and in the summer i have a GIANT Cold sink keeping hole house cold (cold air return only in basement) works amazing! cool my entire house with a 5k btu window unit.

[@DrewWheeler-z6i]

Good idea to check floor for flatness. If high crowns or low spots , pour leveller prior any substrate installation. Laminate flooring or any hard surface flooring looks the best of floor is flat.

[@lucmackay6506]

Hello Jeff, thanks for the videos been helping my own renovations. I was wondering, could you lay the blue dimple membrane down tape seams (for vapour managment) then the durafoam (for thermal break) tape seams with out screwing to foundation, then lay down vinyl plank?

[@HunteroftheNorth]

We live in Barrhaven and I acted as general contractor when we finished our basement. I decided to just use a cork underlayment that had a vapor barrier built in, then put our laminate flooring on top... no proper subfloor over the concrete. That was about 5 years ago and haven't had any issues with moisture or anything yet. If I were to do it again I would probably do a similar type of subfloor like this just to have that bit of extra protection. Thanks for all the great content Jeff. Love that you're local

[@HomeRenoVisionDIY]

Cheers to Barrhaven!

[@cinders302]

Very good lesson. I've been kicking around how to best approach taking the chill off of an older home basement, and I think this is what will work best. Ideally, in-floor hydronic heat would have been first choice, but far too much labour and cost to get a concrete company in to cut grooves for install - plus there would be no insulation to keep heat from being lost to the 'dark side. Perhaps radiant Pex in the walls vs forced air blowing down from the ceiling as it is at present - wretched

[@khg8256]

I really appreciate your videos. I learn a lot. I was going to use Fomular 250 on the floor each board today US Home Depot $58 each. Durofoam at HD $17ish. I'm nixing that plan and buying this stuff. Thanks.

[@jackknife89actual]

Question: would the joint between the wall and the floor be a gap in the thermal / moisture break? Would it be a good idea to leave the plastic, lap it over the foam insulation, and tap it down?

[@job2k6]

I'm in the process of stripping my basement down to the studs. In the kitchen and bathroom, the concrete floor had 1x3 strapping (maybe the proper term is sleepers?) with 2 or 3 layers of OSB on top. Everywhere else is laminate or carpet directly on the concrete. I'm going to be following your advice when putting down the new sub floors.

[@themodernhippy8946]

Works this work over the dimpling so you have thermal and moisture protection.

[@HomeRenoVisionDIY]

yes you can add that but at that point you get pretty high and it might be better to use the dricore insul armor. dimpled plastic plus this insulation board is still cheaper but if you are using a floating floor then insul armor is a better option due to its compressive strength. if you need a nailing surface like me then the home made option is better. refer to my previous video. kzbin.info/www/bejne/aV61eHutoaeqf6M

[@JSLEnterprises]

It should be noted that this subfloor system is only effective for newer construction homes that have 8mil poly under the concrete and closed traversing drainline to the external weepers (meaning extemely minimal water penetration under the slab that would wick). Older homes with clay drain and slab on wet clay, you NEED to use the equivalent of Foundation Wrap (dimple board) under the subfloor you construct, just as he mentioned.

[@BobbyLips]

I have an older home (early 60's construction) and gave up long ago on having a modern finished basement. I do want to have a decent basement floor with good lighting for some hobbies though. I wish I would be able to use this solution.

He mentions that at 3 minute mark. But thanks for the extra details.

[@tangodown2721]

How new are we talking like 2010 or in the last 5 years

[@BobbyLips]

@James Karrie I thought dimple board is only good if you have moisture or maybe a lil water from cracks. With the torrential downpours of the last 5 years until I can reroute water I would need something that would dry out and not be ruined if water entered the basement.

[@ravenstarver1360]

@@BobbyLips yea if you have major water problems DMX dimpleboard won't save you. But it's great for an older home that simply wasn't made for a finished basement and doesn't have major foundation problems.

​@@HomeRenoVisionDIY You rock Jeff! Thank you. I am planning an extension, and in one of your other video's, you pointed out that times have changed in the construction industry. Finding a contractor who can pick and choose what jobs he wants, and then if you do find one if they have the experience to do it right is an issue, so learning to do a lot by yourself, means you most likely will be more willing to do it carefully. I wish I had the skills to put in an ICF basement and 3 storeys above it, as a stick build but high R value walls, outer insulation envelope added. I guess once the more skilled part of the build is done, I can return to DIY'er mode to finish up the interior. Your video's are so helpful. I see you have over 2 million subscribers now as well.

Impeccable timing, I am gearing up to finish my 2400 sq ft walkout basement and was trying to figure out what to do for the floor. I am also on top of a hill with great drainage (if my basement floods I expect to see an ark floating past the house). One thing I was curious on is whether it would make sense to use floor leveler prior to putting in a subfloor? Whoever poured the slab in my basement must have been in the dike business as the floor has a hefty slope from edge to center.

[@HomeRenoVisionDIY]

slopes are all relative. measure the slope over 4' and then go shopping for flooring that has agreeable specs. All floors have allowances for slope and it differs from 1 product to the next. your concern may not even be an issue that needs solving. If your slope is so bad that you can't find a product then consider carpet as an alternative or you will have to install leveler. Cheers!

[@CP-mb7ly]

Concrete leveler is super easy to install - drill, mixing paddle, bucket, and a good (long) level to figure out divots/bumps helps! (Jeff here has a video on it, look for it in the channel!)

I used 1"x4x8 sheets of R5 foam that had a ship lap edge so I didn't tape them, then 5/8" T&G OSB before I framed my walls, then 2"x4x8 sheets of R10 on the walls, then framed my walls on top of the subfloor, ran my wires and installed Roxul R14 batt insulation between the studs, Roxul Safe n Sound between the floor joists, brought 4x12x1/2" sheets of drywall down the stairs and hung that on resilient channel on the ceiling (rooms were 11' wide), then drywalled my walls and finally installed laminate flooring with foam backer on the subfloor. The floor "floats" a bit in some places because I didn't screw it down but it's not bad because the walls hold it down for the most part

[@dberg519]

Thanks Jeff, I love your videos and they've helped me a lot through my basement finishing! I'm just about to get to the flooring so this video was perfect for watching today 😊

[@ewetoobblowzdogg8410]

I'm from up north too. Builders there put the moisture barrier over the interior studs before drywalling them. In the south, building science has taught us to envelope build with the moisture barrier completely enveloping the outside of the building before siding. No basements down here though.

[@ZipKickGo]

Any material touching concrete or exterior walls Needs vapour barrier to prevent mold or rust. Anything with moisture and having no air gap or separation will mold.

[@HomeRenoVisionDIY]

the rule is simple. moisture barrier goes on the warm side. basements are always cold. Cheers!

The advantage with dricore is the channels underneath for airflow. These panels flat against the floor eliminate that? I guess I see in this instance it looks like the walls were already there anyhow, so they can’t be placed on top of the floor over the pink foam board stuff to create that air channel along the floors and up the walls as you show in another video?

[@mitchsteinwedel9268]

the only thing I am worried about is in northern climates we put vapour barrier under the slab so if you are putting rigid closed cell insulation and then a subfloor you are trapping any moisture in the slab which will cause a few issues.

[@dropndeal]

You mean Northern climates like where Jeff is? That would be Canada😂

[@matth8229]

Yeah it's always a bad idea to double up a vapor barrier, which this essentially does. If doing this it's probably best do just forego taping the seams.

[@av1204]

the pieces that are weird angles if you wait to tape them down you can trace them to the osb and no need to measure :D

[@HomeRenoVisionDIY]

in some cases but the 2 sheet goods are a little different in dimension.

[@dfs7979]

I was going to do this with my basement remodel but then decided against it due to the extra thickness - would have had to rebuild the stairs. Ended up using vinyl plank but selected a foam underlayment which keeps everything quite warm. My basement is dry so that will be your #1 consideration. It's also important to flatten your slab for any flooring other than carpet otherwise you will be flighting this all the way.

All 3 combined and I should be able to maintain the aprx 7ft celiing height. Do you have concerns, comments, suggestions on this approach? Lastly, I cannot find a place to purchase the 3/4" DuroFoam you are using in this video. Where does a guy find it or is their an alternative brand to recommend?

[@arlo100_at_jahoo]

Make sure you're drilling your pilot holes deep enough. In the video he mentions the exposed part of the drill bit should be a little longer than the screw.

For starting from scratch (i.e plain concrete everything basement with no framing or subfloor system), what is the reccomended order of operations between subfloor and exterior wall frames? I have the skills needed to build everything in question but I definitely could use more time researching proper water management to make sure its actually done properly. Your various videos on the subject have been a big help

[@ReinierKaper]

Walls first, floors last. Typically only when building up (e.g. on top of joists) would you do subfloor first, simply because it's easier that way. So for your basement, frame out all the walls first, fasten them to the concrete and joists, then you can do the subfloors. You could also drywall first and do floors after, that doesn't matter too much, but because mudding is messy it might be nice to de floors after that.

I like this video. I find the instructions for this system simple and it looks quite easy to do. I need to go to the store and look at this product. Until then...my question... If there are some minors imperfections on the basement concrete slab, when the OSB 4 x 8 sheets are laid over the durofoam and screwed in place, will the durofoam compress a bit to accomodate for these imperfections? Thank! Keep up the good work!

Great video and good to finally find someone offering advice for the Canadian climate. I think I have just found my sub-floor solution for my detached garage. We need some extra space so I'm planning on insulating my single detached garage to turn into a small gym. I'm in Ontario and been struggling to find good advice which is suitable for our climate. Is OSB a good/cheaper alternative to drywall for using on the inside walls of a garage?

What's the best subfloor solution for older house basements (pre 1970's) with walls that have had moisture issues?

What's a similar product i can grab at lowes or home depot?

How do you get water/moisture to flow with no texture or gaps between the foam board and the concrete?
