slab to brick to framing question for garage under construction

[tff]

My garage is in process.
The plan for the walls is to lay 2 rows wide, 3 courses of brick on top of the slab (monolith) around the perimeter. Then the framing would go on top of the brick. I think there will be some sort of straps that attach the frame to the brick.
However, i'm not certain how the brick will or should be attached to the slab. There are no anchor bolts present. Is mortar between the brick and slab sufficient or should i be expecting something else there?

I'd imagine mortar would work. Then set your anchor in the mortar

So were it my build, I would want some rebars, L-shaped, that are cast into the slab, and fitted into the brickwork.

Before that's finalized, I would epoxy some threaded rods into the slab, going up thru the brickwork, but which eventually will hold down the wooden wall framing. Their length would have to be calculated. It would be much tougher to install those after the brickwork is installed (need to go into a ~1 foot deep hole and blow out all of the dust and concentrate the 'poxy at the bottom)

"J" bolts in the slab placed to come between the 2 rows and high enough to go through the base plate.

Thanks for the comments. I may not have been clear. The slab is poured and a done deal. I’m in upstate SC so not hurricanes but tropical storms risk.

Do you have a brick ledge in the slab

What do your building codes require ? I would think that does details would have been in the permit application. I had to submit drawings with all of those details when I built mine and that was 35 years ago.

Really, how is it that this detail was missing during plan review?!!

You will have very little uplift resistance with brick only mortared onto smooth concrete.

Need to have j bolts embedded in the slab but it is now too late for that.

Consider 8x8x16 lintel blocks around the perimeter. This would allow you to drill rebar dowels into the slab at a 30 - 45 degree angle and tie them all together with additional horizontal rebar in the lintel voids. In the lintel voids you could place j-bolts as you fill the lintel void with concrete.

You could also form a 8" x 8" wall on to top of the slab instead of using the lintel block and just pour concrete with rebar and j-bolts as described above.

I talked to my county office today. In my area, slab to brick and then brick to framing with straps is acceptable per code. If i lived on the coast (of SC) it would not pass. Not the best, but it does meet code.

 

[kbs2244]

If the slab is already down use epoxied into drilled holes for the through bolts.

Your mason may do it for you so he can space them correctly.

I wouldn't anchor anything into mortar.

Have you asked the contractor? I would think the process is to do the brick work then layout the bottom wall plate and drill holes between studs then build wall, stand up then anchor through predrilled holes.
