I subscribed to your channel when I saw the ACH value of one of your latest buildings was 0.23, super impressive. That ACH value made me interested in ICF because it made achieving such low values possible with little effort. I will like you to go into details the steps you took when building that house to achieve such a low ACH value. I am very interested in the ACH value you can achieve if you really focus on getting the lowest value. Hope to meet you one day, stay blessed.
Hi Daniel! I’m glad the video helped you realize how easy it is to achieve an air tight home. That was my goal! I will make a video someday on how I achieved that number. It wasn’t that hard.
@@topbuilders3440ACH air changes per hour and is a measure of how many times the air within a defined space is replaced. The lower the number of air changes, the less energy is required to keep that air at a comfortable temperature. If you cool/heat a house with a lower ACH the temperature is maintained for longer because that cooled or heated air is trapped in the building.
In the planning ahead department, knowing the block dimensions for corners and full blocks, couldn't the footings be designed to land on the proper 2" increment? This would minimize any funny cuts.
Kody can you do a video on the attachment of interior finish trim around windows and doors. The way i see it now there is not enough material on window buck to catch a 4" or 6" trim piece around windows or doors.
Hi Dan. 4” trim is easy to attach. The buck is about centre of the trim after you account for the window jamb and the insulation gap, etc. Now if you want to install big trim like the 6” you mentioned, then here are a few options for you. For me I would just keep the standard block and glue the trim to the drywall. There’s no shooting in an ICF so all you need is attachment so the glue can set. All these other options add time and money, You can decide to add extra lumber to the buck so it has 3” of wood all the way around… OR… router 1/2” deep on the inside and remove that foam so you can install strips of 1/2” plywood around the buck , flush with the foam. Then drywall. Now you have lots of attachment in behind.
Hi Kody.., 👋 Can you also do a segment instructing how to do an ICF floor system integrated into a wall solution..??? 😉 I'm referrng to the image in the large poster at the back of your shop toward the left.??? 🤔 It has a car on an elevated ICF floor slab..!!! 👍💯😎 Thanks..!!!
Hey Kody, great to see you back to making videos more regularly. I think I'm finalized on using Nudura. The ability to ship more in less space is a big deciding factor. My only issue is I want to use the Fox blocks bucks. I want to eliminate the thermal bridge. Do you see any issue with using the Fox buck with the Nudura block?
I’m sure you can mix the systems but I don’t know enough about the fox bucks to give you a definite answer. I’m guessing that if the total wall thickness is the same with both block then it should work.
Kody if I am doing slab on grade with a frost wall 42" into ground with ~1.5 to 2' out of ground how do you stagger rebar? Is it same way as if you had a basement?
Yes exactly. Rebar placement would be the same but because you have fill on both sides of the wall it doesn’t matter if you bar is to the inside or outside anymore. I would keep it the same as a basement.
Great suggestion. My first ICF home was built in 2000 and the installer convinced me the ICF wall must terminate flat on the sill. I argued and argued, he went flat and I ended up with frame and stucco gables. Dorks!!!
The scabs are fastened to the snap-ties that are embedded in the foam, I think every 8 inches - which are then fastened to each other "through" the concrete via the slide-in webs. The webs are variable size to allow different core depth.
I’ve never tried. My one supplier ran the math and said it’s honestly not worth it. Below grade where you need more strength you almost can’t put enough helix in the wall. Let alone the expense. Maybe it has its place if you want to do a 4” above grade wall where there’s no room for rebar and a place to run a vibrator down when pouring.
@@uptokode helix micro rebar has received engineering approval and been installed in concrete for millions of cubic feet of walls. Consider doing research on a product before dismissing it.
such a problem , in cold regions -15, there is waterlogging of the walls inside, the solution is to remove the inner layer of foam, and if you do not remove the foam layer , then the water separator and forced ventilation ... good luck to you!!!!
I built ICF in Florida back in 2000. Lived in the home for 10 years with no worries about termites. The outside was finished with stucco though, which probably mitigated the issue.
We pour a 10 ft wall in 2 stages but all in the same day. You pour the 1/2 half and then come around an top up the 2nd half. For additional floors or wall height then yes we set up another 10’ height (or whatever it needs to be) and pour on top of the concrete below that’s been sitting there for a week or so. The key is to leave rebar dowels sticking through the 1st pour so the 2nd pour can be bonded to the 1st and it keeps all structural integrity.
Great question. You can use drywall anchors. And if you do find a plastic tie all the rest should be 8” spacing. That’s the most common. There’s the odd ICF block that has 6” centres.
I assume this: You don’t want the seems between vertical layers to line up. Alternating from short and long corners just helps all the other block to not line up between layers. Keeping the forms stronger. 3yrs late lol.
I wondering the same thing? If you don’t look at the big picture it can seem expensive but certainly not when you factor in all the steps that ICF covers at one time. Factor in overall efficiency and it will begin to make sense
You can add it to the 2nd or 3rd, depending on wall height. Also, if it goes in the 2nd row it may interfere with window/door bucks. If I've understood that all correctly...

Hi, I'm in the process of building our house. No engineerings been done, just 20+ years in construction and research to help get to this point. I tend to over build to make up for lack of technical knowledge so I've used heavier bars and thicker footings. Me and my wife have already poured a monolithic slab above grade 20" and planned on ICF. My original design has me overhanging ICF 2" off the slab as sort of a drip edge and eventually a stopping point for a stone veneer skirt. It also helps hide some of the formwork issues we had on the stem walls. My question is, should I have any issues with the 2" overhang? The foam is 2-5/8" so i will still have 5/8" bearing on the slab. I'm hoping this isn't an issue prior to pour day or on pour day. Any advise is appreciated and because of your experience I felt it was a worthy question for my 1st ever comment on UA-cam. Thanks!
I can’t see there being an issue with the foam overhanging that 2”. Every horizontal break needs a drip cap so the water doesn’t follow its way back underneath the foam and toward the slab. The metal lip of the drip cap is what allows water to break off and fall away.
What is the max wall height you can pour in one shot? I see a lot of 'builders' breaking up the pours (one pour for each floor). That seems like a waste of time/money, but I can see how stacking would be easier.
I want to build my new apartment complex out of ICF but there are so few options for architects and builders here in Houston, TX who can reliably get it right. Any contacts in this area?
I hope you can get it built the way you want it. I would start by phoning a rep from Nudura, Logix, Amvic, Fox or any manufacturer. They will know some people. If you find yourself a practical engineer or architect they will realize this system is super easy to use
No wall is exact and you did not show a wall from ground up that may be in the middle of the lines, let's say if a home owner wants to build the basement walls but leave the house to a contractor who built it to the plans and your way was not quite to the plans. most beginners would not know want to do with a wall that didn't line up because they built it to match the plans proper.
You can make the dimensions exact but sometimes growing or shrinking the building slightly allows for a much easier install. But if dimension was your priority you could do it. Might just take additional time to scab a “vertical joint” as we call it. You have a valid point though
We’ve offset the 2nd floor back from the main floor walls so I don’t see why you can’t over beyond the main floor to the outside. For our situation, the space from the bottom of the floor system to the bottom of the windows (54” high) was the header or lintel that allowed the 2nd floor to span over the main with no support. You’re going to need an engineer
This is off topic but I have a question. Has anyone ever measured the temperature of the concrete in a ICF wall? The ICF wall is sitting on a concrete footing. In colder climates, how much thermal transfer is there from the concrete footing up the concrete? If the footing is 50 degrees fahrenheit, that would the temperature of the concrete be above ground?
Do you think ICF is a beyineer DIY project? If yes, why most ICF video done by contractors say: ICF is not a DIY job? If no, then what is the use of posting how to videos? (Apart from generating income for poster)!! Can you make another video explaining whether ICF is a DIY or not?!
Would love to see how to check for level and level the blocks after the 2nd or 3rd row as I know that can be an issue if your footings aren't dead level. Maybe that's the better route, is to ensure your footings are all dead to rights level.

Hi, Kody. Thanks for the video. Did you screw the scabs on cut ends to the foam or to something solid inside the foam or inside the form?
The scabs are fastened to the snap-ties that are embedded in the foam, I think every 8 inches - which are then fastened to each other "through" the concrete via the slide-in webs. The webs are variable size to allow different core depth.

How do you feel about the Fast Foot monopour system? Can you do a video on that?

@@uptokode Yep, it's by a company called Fab-Form.

Never seen or heard of this before. You definitely need good ventilation and fresh air in the building but it never gets into the walls.
Do you have a paetron account or link?
Obviously termites are not getting through poured concrete, but I have heard they like to eat and tunnel into this foam. What are the facts please??
I think they make ICF that is termite resistance and If you put a good barrier I think itd be hard for termites to get into the foam
I don’t know the answer to this. I keep getting more questions on it so I best do some learning.
We don’t have termites where I’m from.
@@uptokode yes please do. Big swaths of the USA are termite areas.

@@uptokode awesome thanks Cody, i was thinking if all else fails ill use 8" tapcons haha

Maybe a magnet to find the drywall screws. You could then measure 8” to your desired location.

How long does it take to build an ICF house if all equipment are on site and the weather is perfect?
That depends on a lot but no more time than any other build. It takes care of more steps at one time.

I’m sure there is. Ask you local ICF distributor to start. I like Nudura so check out www.Nudura.com.

How much overlap you need for bars in vertical directions? For example for second floor walls over first floor wall.
The rule is 40 times the diameter of the bar you are using. We just go 2 feet to keep it easy.
If you were building a shop/garage or other tall wall (say 16-20’) would you pour it in one shot?
I like to pour 10 feet at a time. Hard to vibrate much taller than that. But I know guys who would pour those heights in one shot.

Why not cut your blocks to have a common vertical seam for the side that didn't come out to a standard length?
That’s a good question

In colder climates, how much thermal transfer is there from the concrete footing up the concrete? If the footing is 50 degrees fahrenheit, that would the temperature of the concrete be above ground?
