The Modest House Build Ep 2: Foundation Insulation and Backfill
HTML-код
- Опубликовано: 23 янв 2025
- In this episode of the modest house build, we start with foundation insulation and finish with backfill. We use the AMC Foam graphite EPS Halo insulation on the exterior to reduce thermal transfer and clean 3/4 stone for backfill. This reduces the need for compaction and is easy to work with down the road for the concrete guys.
Big thanks to AMC Foam for supporting us on this build.
RR Building Plans available here. If you are looking for this build specifically it will be on this page and available soon.

Video has gotten so much better who ever is filming is doing a great job. Thanks for giving Greg a mic. Do let Greg do more work and also take on his ideas bc I voted Greg’s way of putting up board first then going thru with the saw to cut off the extra, would of save on that battery. You guys are great love content.
love the safety squints at 6:45
It’s pure joy anytime I get to hop on a piece of machinery and move material. It really speaks to that inner child that played with his Tonka trucks and Tonka toys until dark. 😂
I don't know how much you pay Greg but he deserves a raise!
Buy Greg a house 😡
I'll 2nd that 😂😂
we found Gregs burner account lol
Kyle spends his life over complicating things (which i appreciate), but when Greg does it just 1 time, by suggesting a ramset, Kyle says, "no, we don't want to over complicate things"
I just filled in my foundation with stone. Use a slinger truck and I’m glad I did!
Haha Greg asking “I am getting paid..right?” And looking at the camera had me dyin’! Good job guys! My son liked it when you went to the gas station in the skidder.
I marvel at the thermal efficiency you put into your builds, in Australia my experience is that builders pay little attention to it, indeed many new homes are built with thermal insulation as an optional extra. I suspect many builders regard a blower test as something the Random Breath Test cops do to them on their way home from the pub
You guys are great. Seriously I'm envious of the program you guys got going
Liked the video after 30 seconds! Love the channel, big respect from 🇬🇧
Gotta love having the BP next door! That came in super handy!
QUALITY SELLS ITSELF
ALL DAY LONG!
☮️💜🇺🇸
Good work guys. Excellent channel. Been watching for ages and look forward to each new build or story.
30 + minutes of gravel moving..... Just for the commentary! Love the banter!!
This is going to be a great series
I agree with Greg, use atleast 1 ramset to anchor each panel. Dirt compacts and can shrink. Don't want gaps next to the CIP wall....
Anxious to see this build come together. This is close to what I’m wanting to have built.
Wouldn't it be a good idea to waterproof the cement wall then add the foam? Might even suggest adding a french drain around perimeter. Water always finds a way inside even with extra prevention.
Does that matter if it's under a concrete floor?
Slab on grade construction… water under the floor isn’t a problem
This is not a basement ,waterproofing the rocks (backfill)
When you say French drains do you mean footing tiles? Most of the time you won’t see footing tiles on short foundation walls like slab on grade or crawl spaces.
I'd be willing to bet that Greg was sore as hell the day after hand shoveling that gravel, 💪🏻
Greg is a Beast dude. He just shakes it off like the Superman he is. Did you see him Fly over that wall? It only took the “old” guy 2 mins to scale it After looking at it for 10 mins and psych himself out 👍
He is a ninja
Multimillion dollar company but no battery charger?? You guys are still awesome!!
yeah, I caught all of your RR HQ 2.0 build and saw you use the Halo Subterra styrofoam on the foundation of your new building; really seams like a great idea to block condensation and to insulate the foundation!
Right up my alley guys. I am just about retired and you are building almost my retirement place.
I don't know the details but i think you will have a thermal bridge on the front porch an on the rear porch corner where you have uninsulated foundations perpendicular to the insulated ones. It will probably have negligible effect to the overall performance but it is a cheap and easy detail to do.
Thought there same thing
Love this one. Just like watching Bob The Builder with those two Kubotas.
Good thing you guys are in Illinois. Once I get my piece of land expect a call. 💪🏽
Greg is the real Star of the show. Someone has an Instagram with everything Greg. Some funny stuff on there.
Did you mean Tik Tok?
@Highlander-ys2ei No
I was waiting for Kyle to have Greg cut the panels so that the logo's match on every seam. This will be a fun build to watch!
Gotta love those kubota’s!! I love mine!!
At 2x, you and Greg in both skid steers reminded me of the tire changing forklifts of “Cars” movie.
I would be concerned with the snow under/ mixed in with the gravel. When I was a concrete contractor in the eighties a Super backfilled a foundation that had about 8” of snow in January. The floors got poured and the building enclosed. In July the snow melted and all the slabs ended up needing to be hydra jacked to fill the voids.
Watching Greg spread as much stone as he did by hand was insane. That guy is worth gold these days when it comes to employees. You just showed your new kx 80 excavator in a previous video. Put a four foot clean out bucket with tilt on it and you could have back filled all edges with stone and not killed Greg.
You should have a welder's hammer (the pick type) with you. If you cut the back edge that's flat, it becomes a very useful tool to use in the concrete phase of the work you do. Over pours, little edges, stuff you need to clean. Best tool.
This will be the series i watch to help me decide on how to go about building my own place.
Lol
Dude bring out your excavator . Set it up inside and bail it ii
It's like watching a video game with the two skid steers moving back and forth in double time!
Time for a wheelbarrow. or maybe two wheelbarrows. Thanks for the video. All good man. Congratulations on a very cool job.
I think Ive watched just about every show you guys have done and I love your work and your attention to detail in your explaining of it all. Thank you!!! But Bro why not use a gravel shooting truck on this one?
Why fill the foundation with gravel instead of dirt?
sawzaw with a chalk line on the outside would have been faster, but hinds site is always 20/20! The speed square worked real good lol
I figured you would have used an adhesive to hold the foam board to the wall.
Closely following this series.
A little spray adhesive will tie those foam panels in good. Imagine if you had cut that corner so the ends fall together on a 45 cut. It would have looked so clean.
sorry greg RRHQ has to get paid off somehow!!!, such an amazing volunteer.
It's awesome you guys are doing the site work also nice video you 2 do an awesome job
No weeping tile for drainage?
If it were mine,,,, id have added an underground shelter in the living area part. Could serve as storm shelter/gun vault, valuables vault etc.
What are the advantages to using post frame rather than traditional stick built on this particular project?
I'm curious about this as well.
@@Matt-mq1ep /stronger, thicker walls, just for starts
@@glennwest4438 Not sure if he said what the post thickness is yet, but I'd be curious of the load capacity of I assume 8 foot spaced posts vs 2x6 walls. Post frame also created more headaches if interior walls are framed in 16" oc like standard walls. I helped a friend do his and it was a pain. Not trying to be a dick, I'm genuinely curious of the overall picture.
@@Matt-mq1ep One just runs 2x4s horizon to wall stubs and put dry wall on it, Space it every 2 ft. Simple. Same as outside for siding.
I’d love if this is actually Greg’s house that Kyle gifts him right a the end for all his hard work and loyalty 👌🏻🤘🏻
Looking forward to this design. My wife and I here in Iowa been contemplating building a structure like this. I need a bigger shop and we are ok with no basement as we dont really use the one we have at current house.
Amazing video. Thank you guys so much
You guys are killing it again, boy that's allot of rock!!
What was your thinking on just filling with gravel instead of doing lifts and pack.
That is a lot of fill material for a house! How much did you raise the grade?
Greg was right again, use a saws all
Nah that wasn’t the answer. Precutting on the pile was by far quicker and cleaner
Look like Greg is the Snapper King. Reminds me of a lady that went on a chartered fishing boat with seven business men. Yeah, she came back with a big red snapper....
Should have removed the snow before spreading the gravel. If you place the concrete before it's melted, you have a good chance of having voids under the slab.
It did not get compacted properly in lifts either, so I'm sure there will be some voids regardless.
Its quantity is really negligible. It will drain into the soil eventually. What “bothers” me is the lack of any geo textile on grade inside the house foundation to separate soil and crush rocks, and the lack of insulation between the porches and the house foundation. The rest is to be seen. But by the meticulous process/labor RR used to build it headquarters I think that the building will be more than great.
@@Matt-mq1epthat’s clean 3/4 rock or sometimes called cm11. It reaches almost 100% compaction on placement. Really no need to compact. Similar concept to using pea gravel under pipes.
@@Matt-mq1ep stone does not need compaction
Clean stone doesnt pack
i have nothing against team kyle, but at this juncture i am firmly team greg.
22:27 Kyle, Chaney enterprises makes a concrete and aggregate calculator available for iOS. It is simple and accurate. I use it any time I have to calculate concrete or stone backfill.
Love the safety squints while cutting 😂
Most people would tamp down the gravel in lifts to prevent some of the settling.
An amazingly interesting video. 😮
My guess is they will build the structure now and slab will be poured after it’s all closed in. Lots of traffic on that gravel during construction so should be compacted enough by the time it’s ready for concrete floor
Love that butcher shop across the street
Make sure you backblade with the cutting edge to avoid wearing out your bucket.
1st time seem yoh building a house❤
Nice hustle guys.
I'm excited for this build.
I'd love to see cost info (approximate anyway) as you went. What did all the gravel cost? The concrete? Insulation?
why not a beveled cut on the foam board?
CRAZY amount of gravel fill, surprised customer did not want to use that already excavated space under the living area...
That dirt is beautiful!!
I was really expecting a conditioned crawl space as well.
@@calvintittlemy thoughts as well. Must be a reason.
Are you not planning to coat the outside of the base with a sealant and drain matting? The biggest weakness in those foundations is the hole from the form bracing holes. Hydraulic cement and some tapping of the metal back into the forms will seal things forever.
Im wondering what the cost difference was from paying rental and installation of form boards, now installing insulation boards, rather than paying for icfs? And you get the 2 in one. And save for no stripping of forms.
I thought ICF's would have been a good choice for this too
I agree, icf’s seem like way less labor. Watching Perkins Builders do metal forms took forever
What about facilities under the slab ??? to do later on ??
Why dig out between footings? Made a hole that didn’t need to be made to then fill?
no water barrier on foundation?
Can build a post frame building with a basement? Thanks John
What is preventing the concrete ties from rusting and spalling the concrete given they are in a high moisture area? Plus huge depth of fill with ground bearing slab (not tied to the perimeter wall to suspend it), but with no compaction regime, what’s reducing risk of (differential) settlement and slab cracking?
It's a amateur oversight.
Ties should always be snapped off and sealed especially below grade where water can penetrate through the tie to the other side too.
Simple building better practices
I really thought you guys would have compacted the stone fill every couple of feet especially around the edges 🤔
How come you didn’t backfill with gravel on outside of building?
Great video guys .. could u build on of these homes with a basement..?
was a weeping system installed?
Hey Kyle, is the reason for all the fill because the grade from the street to the house was a bit downhill and you needed to bring everything up to make it uphill? Around here, a tri-axle full of 57s (25 tons) runs about $600, delivered, so those 12 trucks would be north of $7k, and that's not counting any stone that went under the foundation walls. And once all the fill gets put in and compacted, is that when the plumbing rough-in happens?
Why did the slabs need to be so far above ground level? It took a lot of gravel to fill???
What about Rock compaction?
That's going to be nice plus the chevrolet dealership is right there for easy maintenance of the HD
So i heard someone on a podcast say "if you are a carpanter and you are working without your bags on you are not a carpenter, you are just fing around" as a carpenter that finds himself doing that occasionally it made me laugh. Thought i would share.
Has anyone besides me had a problem with termites traveling behind the insulation? I had to cut insulation down to ground level and replace outer floor joists because of termites.
@terryquaintance3634 I have had the same issue but in remodels when I found the foam board riddled with mice nests
Serious question, is there no concern of voids forming after that snow that was buried melts?
This is going to be a great build, but the next evolution will be building over a basement. Now that Kyle and Greg have access to the rotator telehandler, placing trusses over a basement wouldn't be much harder.
We’ve done that a few times
How do you handle Damp proofing the wall?
I think I would’ve set up a table saw for the AMC foam board, just my thought.
Does that gravel need to be compacted one "lift" at a time?
Will it maintain it's intergety over time?
I'm glad it's not my foundation.
was thinking the same thing. i did 12" of gravel at my place and compacted it. for the garage, being a different height, we did a bunch of sand which we compacted as much as we could (not ideal placement, lifts weren't very flat), and letting it naturally compact over the winter before pouring the floor pad
I'd say those 10-12k machines rolling all around on it will be just fine. Sure a plate compacter in small lifts would be better, but with crush and run and those machines it will be fine. Plus there will be foam board and stuff on top of the gravel.
@@jakewhitaker2502 nope. Those are track machines specifically designed to minimize ground pressure.
Depends on the gravel, I've used some type of gravel before where compaction wasn't required. Because once placed it sits 100% compaction. You don't want to use it for a driveway material but for pad prep it works good.
@@ratoneJR stone does not need to be done in lifts or be compactec
Did they put up Concrete panels. or Filled panels with Concrete?. The outside Insulation soo easy to fit. And Greg in a T shirt while snow all around😁 gonna be another great series. Cant believe you said that Kyle, Youre a MAN working on a build site and said dont want to dirty my PRETTY Hammer!!!😁😆
Kyle is very protective of his ramsets
Sweet bowling shoes Gregory
A stone slinger truck would have save you a boat load of time with installing all of that gravel for your foundation. Are they not common in your area?
My thought exactly...
They are quite a bit more expensive than delivered gravel. Especially for 22 loads. I bet using the machines was more cost effective.
Leave it to go up to the house no wind in the bottom space
could they have dumped a huge pile of gravel in the center before the concrete was poured?
Kinda surprised you didn't put the stone in lifts and compact if it's for a slab.
Shouldn't you be packing the gravel every six inches of thickness so it doesn't settle when the concrete is poured?
Did i miss it or is there a rendering of the finished build?
