Now ready for the concrete in the pole barn

[ovrszd]

That's a lot of people. Had a 8k sf slab poured a few yrs back with 4 guys or so. (laser screed and pump).

Think 3 guys did my 30x48 barn.

I recently drone shot a 100yd pad pour with 8 guys.

I am no concrete guy. I enjoy watching a crew that know what they are doing. Especially doing the finish work. The guys that just finished my shop pad (39ﾗ48) power troweled it for 2 hours.

Mine was a 36 x 48 with mesh and in floor radiant heating pex tubing tied to it. Underneath is 2” foam boards on a VERY level bed of sand.

Concrete was fiber engrained, pumped in using a pumper, finish trowled smooth and cut for expansion. Didn’t use rebar and there’s absolutely no cracks anywhere. I believe the key was adequate preparation & proper compaction to eliminate any settling.

I ran my electrical to boxes overhead and dropped them down wherever I needed them through the ceiling, rigid piping on the walls.

My concrete guy says rebar or mesh doesn't stop concrete from cracking. They help the two pieces from drifting apart.

Says slowing the cure process can improve your odds in limiting cracks. Cracking is caused by water evaporation which shrinks the concrete.

Expansion cuts are to control the cracks. If you haven't filled your cuts you might look closely at the bottom of them for hairline cracks. That's their job.

A solid base holds the pad at whatever elevation and grade it was poured at.

I asked a lot of questions.

Like I said in your other thread, take lots of pics!!
Here is my 40' X 60' for my red iron building, 66 yards!!
1st- site prepped
2nd- re-bar and wire (per engineered drawings)
3rd- finishing up the pour

I must have missed something.

WHY are you running conduit under your slab?

The walls are 16'. Easier and cheaper to run the conduit under the slab to reach the other side. Will take to much wire to go up a 16' wall then across the trusses and then back down 12' on the other wall. Not a fan of having all that romex exposed.

WOW...thats alot of concrete !! I do know red iron buildings take alot of concrete per engineered plans. Looks nice !!

It's actually cheaper to run conduit and individual wires than Rex.

So, assuming the source is 4ft high. 4ft down, 30ft across, 4ft up uses 38ft.

12ft up, 30ft across, 8ft down uses 50ft.

Saving 12ft of wire by laying 30ft of conduit? Not sure how that pays out.

Sometimes we just gotta do what feels right.

Like the way the angled rebar was laid in on the corners and pier / post

Maybe someone doesn’t like heights.....unless it has wings and a yoke.

Good explanation ! Makes sense to me. The soil is well packed so no fear of the truck rutting it up !

That truck weighs A LOT! I would go the route of placing after the truck backs out our you could have a real mess on your hands and a short time to fix it.
