Absolutely right An HI.
I read the post and then just glanced at the photos, but in no. 3 you can see the sheathed wall structure and floor sheathing resting upon a 2x4 rim joist (?). The wall has been held back from the edge the thickness of the sheathing so that the outside of the sheathing aligns with the outside of the concrete wall.
The embedded x4s are obviously backing for something, probably either a deck (not a very good method, but likely because they didn’t extend the tyvek down over it) or for the exterior wall covering (in which case they might well have extended both sheathing and tyvek down .
Any wood embedded in concrete and left without a breathing space, especially wood exposed to the exterior, would have been better made of treated wood.
Now I’m curious about the 2x4 rim joist. Did they use undersized top-flange hangers and notch the floor joist over the top of the plate?
Ladder sills. Standard practice here, it is simply too dry in Alberta to be an issue.
What is a ladder sill?
A photo please Rick.
Yes I worked Calgary,in the Spring,Summer and Fall. Dry as a bone. Roofing large projects. I remember my perspiration would disappear. No sweet.
110 days I would be dry as a bone.
Muskeg ain’t dry Rick, ha ha ha ha. I worked Oil in the freeze ups.
That being said.
Love to see more photos as the home evolves.
Note that some of the 2"x 8" material is proud of the concrete.
Lobe to see them ladders Rick.
Ladder sills are very common and porcupined into place. Build a 8" 2x4 wall 2’ on center and install it at the top of the form. Use 3 1/2" galvanized nails inside the form installed half way to be embedded into the concrete to help hold it in place. Bolts are not required if this system is used.
Here is a photo of modern ladder sills being used in my area. Un-treated wood in direct contact with concrete above grade. This design allows the wood structure of houses to be fastened to the poured concrete foundation walls.
Prior to this design many houses were built with un-treated wood joists and beams embedded into the concrete foundation walls. I have seen houses dating back to the 1940’s with no deterioration of the wood. I have also seen many floor joist systems resting on top of concrete foundation walls with no sill plates and no means of attachment whatsoever, simply relying on gravity.

Thanks buddy.
Fasteners on the face of the board material. 2"x 8" , facing the concrete. No cut ends treated ?
They still use double plate the framing ? The ledger is like a rim joist so to speak. It sandwiches the concrete with a double sill plate on top.
They anchor the top plates. Normal fasteners ?
That is a great idea. No need for mechanical anchorage every six feet for the top plates.
That would have to be flashed well and treated wood used in Quebec.
Thanks again.
Love it.
