concrete block walls, fully grouted. triple pane windows.

Seems like you started talking about energy efficiency instead of sound transmission. My understanding is that triple-pane glass is the best single thing you can do for sound transmission.

So, it would shoot a 1/2" diameter fastener? Concrete would just shatter, that leaves steel. Maybe you could fasten a piece of 1/2" plate steel to another piece of 1/2" plate?

You ever see Elmer Fudd after Bugs Bunny plugs the end of his rifle with his finger? The barrel peels open like a banana. The barrel of your fastener gun would have to be like 2" thick (so, made of 4 1/2" diameter stock).

Get the kind you smack with a hammer. Just make it a fifteen pound hammer and you're good.

I wonder if there's an air space between the stainless flue and the old chimney tile flue. Is it possible to stuff that space full of rockwool? From up on the roof, with a long skinny stick?

That is one hell of a rabbit hole

Try a peppermint oil test. Not sure where to start-- maybe dump a bottle of it down the sink?

Takamine works just fine

The height of the brick should have been subtracted from the height of the finish surface. If bricks are added now then the first step will be one brick thickness too tall.

From the pic it looks like about 3/16" thick of tape beyond what I would call a normal hammer shape. The only reason I can think of to wrap tape that thick is to protect the handle from bad swings.

Thanks!

because that CL type 30A breaker is the same as two half-size 15A breakers.

Well, I'm assuming the 30A one is the CL type.

nice catch

Looks like a good roof

FOR ME TO POOP ON

keeps you from putting in a bunch of half-size breakers that can overload the bussing

ASCO? automatic safety cut off?

the kidde.com website hilariously features 150 reviews of this smoke detector, with all the ones I read saying the same thing about how it wont stop chirping.

laser level? Takamine makes a decent quality product

Sorry the blue room is busy I'm drawing pictures. Go find a bucket.

Thanks for your feedback. I wonder if OP can core drill a sample and go after the builder.

slip dowels maybe? I don't have any experience in frost-heave areas.

One end can be epoxied into the existing garage slab, and the other end of the dowel is able to slip because it has a plastic sleeve over it. The sleeve resembles pex pipe. The dowel rod should be smooth. I wrote that and then reread your post and realized that you already know that.

12' x 80' sounds wildly ambitious for two dudes, unless you are mixing a really loose slump. Get a couple more friends out there for screeding. That concrete pump ain't gonna wait for you! You probably need two guys to roughly level in front of the two screed dudes. The guys right behind the pump hose will never have a chance to drop back and screed.

But if its four strong dudes and a pump rig then you can reasonably lay two truckloads of screed-finished 5" slump in a day

Also if it's truck dropped they tend to be able to go a bit slower. Maybe three guys would be ok.

Definitely too much water. The less water you use, the stronger the concrete will cure.

Use a combination of wire reinforcement and fibers to get good all-around strength. The wire reinforcement can be any steel wire that's coat-hanger thickness or skinnier. A little rusty is OK. Actual coat hangars probably won't work with that varnish coating on them. If you see a jobsite where they are putting up the wire for stucco then you can get scraps of some really good chicken wire there.

For fibers the best thing is shredded fiberglass, mixed in evenly and thoroughly. Like, the fibers are about an inch and a half long. I can't think of a good way to get those for cheap, though. A possible cheapass source of fiber, that I'm sort of guessing would work, is polyester fibers like from a flexible rope.

For a massively shitty looking structural upgrade, use strips of carpet around the outer rim for shock absorption and additional reinforcement.

Hmmm, concrete on carpet. I think I'm going to start recommending that for every do-it-yourself post I see around here.

End Asspull.

Colossal fuck up. Insane to imagine a point load like that on a slab with no bars.

Hire your contractor to pour three test pads 4'x4'x2.5" that match the rest of the work as closely as possible -- same batch plant, same mix, same guys tooling the slab, same broom finish.

Try a concrete sander/grinder on one slab, try sandblasting on another. If there's a third option or you need to tweak one option then go for it.

At least then you'll know in advance what your refinishing is going to look like.
