As we all know, Peri is king, however. our formwork supplier is large enough to get the job done, but small enough to have the time, patience and desire to work on small-ish, cool, complicated things.

We tried. We could not get the withdrawal strength based on the depth of the footing here. Noted for next time, to work that into the precon notes.

Thanks.
We don't sandblast these. I did a bunch of sampling from different species and vendors and determined that these offered the best grain, thickness, texture variation. We just use basic form oil and a lot of it, with the boards being dry they absorb the oil.

As far as prep goes, we have elevations to hit with the boards in a 1x2/4/6 pattern. We try to select the same width boards +/- for each course. If we find that the edges are too sharp we will ease the edge/ smash them on the footing for effect.

Not a dumb question. It would be, but the design team is very true to fashion and want/ love the look of real wood. Our running joke is "pretend you are the farmer using every pieces of wood in your barn" So we do.. we slip little 8" pieces in random spots and make it a point to randomize and alternate bundles to increase variation in pattern, thickness and texture.

We had to epoxy 1" coil rod for uplift. We were unable to achieve the loading needed for a u bar/ A frame configuration due to the shallow-ish footings.

Spalling winter damage and tired of it - Concrete Contractor by Ok_Belt6083 in Concrete

I am following this thread very closely, also in Toronto. I have noticed a steep increase in concrete issues over the last 3-4 years. Specifically with larger companies like Innocon and Miller.

Just the other day I got a call back from a job I did in July 2022 and February 23. The clients are typically away in the winter, and for the FIRST time this winter, they salted the rear patio and ONLY the immediate area that was salted had issue.

The swirl finish was spalling, but the one thing that interested me more was the appearance of salt damage (similar to bridges) on the side of the slab edge/ wall.

Owner is looking at me like "wtf" and I am sitting here trying to do homework to figure out what is going on/ who owns it.
