For anyone following this thread here's what I ended up doing: I modeled up the templates and 3D printed them out of plastic to align the anchor bolts together. Then I had my buddy waterjet cut that same template out of 1/2 inch steel plate (its what they had around). I then used the 3d print...

There’s no “proper way” both ways have perfectly sound reasoning to them. If the subgrade isn’t flat you’re going to have voids whichever way you do it. I got my sub grade and the foam within 1/2 inch which took a lot of work, but will save you a lot of headache in the future. They’ll always be...

If you spend some time getting at least the footer flat it’s not too bad to insulate. Where I live the frost is 4+ feet so I wanted to protect the outside edge from frost heave. I would have done a conventional foundation but already had hammered out feet of hard granite to get it where it is...

I’m using fiber glass rolls in mine. When I finish it I may put a layer of rigid insulation behind the walls.

For anyone who looks this up later for refence gets how I ended up doing mine. All parts were later taped together with pex stapled to them. I put foam where I could get it flat enough to not rock or create voids. Any place that ended up curved I left alone.

I ended up spending a lot of time smoothing out the bottom of the thickened edge which I did insulate. I got the first few inches of the slope flattened out too and may run a piece up it but not going quite all the way to the top. I will include some pictures once it’s finished so the next guy...

Agreed but they can be limited, especially with heated floors where the slab is the warmest part of the building. I wanted to figure out how high the risk is of putting down possibly poorly unsupported foam and if the benefits would outweigh that.

Same!!! Lot of people smarter and more knowledgeable than me on this forum. They way I see it the more information I can get the better.

For those of you with thickened edge slabs single pour slabs (Alaskan slab), did you put foam board down in the footer or haunch? From my research I've seen it done both ways. I'd prefer to put foam board down over the whole thing as I want to minimize any "thermal bridging" where my radiant...

Looking for pictures of your frost protected shallow foundations or “Alaskan slabs” before the concrete. The flat part under the slab isn’t much of a concern, but I’m laying XPS over the sloped sides of the haunch and was wondering how meticulous I really need to be with it. All the diagrams I...

I have my shop site prepped and ready to pour the slab, and while going through the engineer’s notes, I noticed this section: “All footings and slab are to be treated with a termite control pesticide.” This caught me a little off guard since the structure is steel and concrete. I’m wondering...

@rmack898 Wow thank you that picture was helpful in more ways then one. I have the same slab style as you with the thickened edges and the 4 ft blocks for the columns. What size mesh did you use?

Yeah all bolted. The welded option was slightly cheaper but I wanted to do it myself and didn't want the headache.

I've taken your advice before, and I'm glad I did because it saved me a huge headache. The broker told me to I'd be fine unloading the building with my tractor. You recommended getting something bigger. I ended up borrowing my neighbors front loader with forks and that was able to unload the...

Mistakes happen, but I'm definitely trying to avoid something like that. It's not gunna be a good day if I have to bring the torch out.

I just got off the phone with the engineer who put together the plans, he said that epoxy would be fine if the holes were at the same depth as he specified for the L bolts. It might be easier to measure and drill the holes afterwards. One less thing to worry about with the pour.

My original plan was to 3D print some fixtures to hold them, and hold them off the ground with some rebar.

Yes I will be putting it up myself.

For those of you who have a red iron steel building, how did you set your anchor bolts? I was planning on making a fixture to hold them in position and have the concrete guys pour around it. The concrete guys want to wet set them, which I am a little skeptical of considering there's a short...

Must have been a miscommunication, you guys convinced me to NOT to worry about it and place my vapor barrier underneath the foam.
