I am building a Barndominium with 2 zones of 1/2” pex radiant in slab heat. First zone 2490 SF 8 loops of 300’ and 1 loop of 200’ 10 loop manifold Estimated to need 68475 BTUs/HR Second zone 400 SF 2 loops of 250’ 2 loop manifold Estimated to need 9100 BTUs/HR I need help figuring out the...

I had 28 piers and work alone, so wetsetting them all wasn't an option. Not a lot of time to fuss with them while trying to manage the concrete truck and smooth the tops. I drill set mine, but Sturdi wanted $130 a piece, so I made my own.

I haven’t decided on the lift yet, but it will be a 12k two post. The install instructions I’ve found online state min 4” concrete under 10k, 6” over 12k. My concrete guy is going to cut in the expansion joints 12’x12’

VA - 24” frost line No, it’s a floating 4” slab with 6x6 remesh. Re: WSSIX99 - I’m pouring a 4” slab with 6x6” remesh. The 12k lift calls for minimum 6” slab. You’re saying just leave it all 4”, or pour it all at once just deeper for the lift posts?

12K lift. You wouldn't be concerned about the floating floor trying to float and the point load of the lift causing a crack?

I'm building a 48' x 64' post barn with a 4" floating slab - 6x6 remesh - 3500psi over 4" compacted #57. The lift specs say I need 6" rebar reinforced min 3000psi 4' x 4' for each of the posts. I plan to dig these 4' x 4' squares out a little deeper to allow for 6" concrete depth with #4...

I dont have a designer, but I can tell you having done all this work myself - you dont want any smaller than 16" piers. The sturdywall columns take up a lot of space and you dont wanna drill too close to the edge. If I had to do it again, I'd do 18" piers - and spend a little more time in the...

I’m in northern VA. Still getting quotes, I’ll put some pics and pricing up as I get it. The piers better not heave, kinda the purpose of digging them below the frost line. Agreed that slab will float in every direction. It will have to compress the 2” foam vertically or horizontally before...

Agreed. Piers won’t move, but the slab will no matter how much I compact. It’s over 36 yards of concrete! I will be compacting earth and 6” of gravel every 2”.

Depends on the insulation cost, but I’d prefer all 2”. At a minimum I’ll run 2” in 2 rows and gravel up to 1” insulation for the center. I don’t want any uninsulated areas

I don’t understand pinned vs moment connection. I can say that the slab is floating and provides no structural rigidity to the barn. Therefore I need it to float independent of the piers. My concern is when the slab and piers settle at a different rate, the slab will crack around the piers. I...

6 x 6 bolted to piers with sturdi-wall brackets and lateral cross bracing in all corners for lateral stability. Exterior gravel halfway up skirt to a couple inches below board/batten siding. Inside concrete poured to top of skirt board (which will be wrapped with 2” foam board down to earth.

Concrete estimates are coming in around $25000. I can only imagine what they’d charge for pier perimeter relief cuts X 28 piers 🤦🏻‍♂️

My barn is 48 x 64, the Radiantec folks said to do the outside 4’ with 2”, the next inner 4’ with 1”, the the remaining center no insulation. He said the heat loss through the center was minimal. As long as the insulation isn’t COVID priced, I’ll be putting 2” under the entire floor.

Yes, Kyle and Greg are my mentors. Sadly this video shows my connection issue but doesn’t address it.

I’m building a pole barn with 16” sonotube formed piers every 8’. My 6x6 posts will be bolted to the center of the piers, with a 2x6 rake board running horizontally between the posts at the bottom. I plan to cover the rake board on the inside with 2” foam board from the top to about 10-12”...
