I have nothing to say. As it turns out I have a fair bit to say. When I started it felt like I had nothing to say.
Slab poured beautifully. The finish work is beautiful. The retaining wall at the south side of the garage started to bow in the middle. They literally dug the concrete out from around the rebar, added a whole bunch more bracing, realigned, and then reloaded the concrete. Pictures are in the Pictures area. It's a thing of beauty.
On to yesterday's issue.
Current thinking is to remove the existing slab.
- Pouring a slab on a slab is not optimal. And then we'd have to raise all the plumbing.
- Pouring a thin slab (which it would be towards the NW corner of the house) is even less optimal. It'll crack. You just know it'll crack...
- We can remove the slab with minimal disturbance to the new plumbing and bad old stem wall.
So we get an estimate in the AM.
Assuming we go this route, not-with-standing the color of the floor, we have a couple of new considerations.
- The bad old stem wall is 8 inch block.
- The good new framing is 2 by 6 with drywall. The finished thickness is 6 inches.
- If the slab stops at the bad old stem wall, we have 8 - 6 = 2 inches of bad old stem wall that will be visible (either on the inside or outside) since the concrete slab is the finished floor.
So what to do:
- I suppose we can put down some 2.5 inch thick base molding
- We can frame with 2 by 8 lumber
- We can shift the framing so the finished wall before we apply base molding is at the inside edge of the stem wall.
- We can make the stucco thicker.
There are probably more variants, but those seem like the big four. CtC and the concrete wizards are sorting.
Another consideration is what is the new datum for the new floor coordinate system:
- Start at the high (NW) corner and hold level so the slab goes above the stem wall on the lower corners.
- Start at the low (SE) corner and hold level so the slab is below the stem wall on the higher corners.
- Find a compromise where the slab is above the stem wall in some places and below it in others.
I suspect the compromise is the best worst alternative. CtC and the concrete wizards are sorting.
Another consideration is where to put the score lines. The score lines are actually cuts in the concrete so it has a place to fail gracefully. Too many lines is expensive and weakens the slab. Too few lines and the concrete is left to it's own devices. The lines are pretty obvious, and are going to be dirt magnets so we need a balance. John (one of the Concrete Wizards) and I worked up a compromise with the prints and a pencil on the hood of the Volvo (the Volvo of buttery soft leather that was not a factor in our choice, but it is comfortable). We chose the Volvo since it was on the order of 150 degrees in the unrelenting sun of the Quail Manor and the Volvo was in the shade of DnT's carport.
The compromise is 20 blocks of roughly 7 by 6 feet as shown.
Now I have nothing more to say.
Probably plenty tomorrow. The block guys start into laying. Today they hauled blocks like nobody's business. Very very very hard work. With all our piles and footings there is no way to get a machine into the backyard. When the garage dries we will be able to drive through, forever. There is a garage door on the front and back. But nobody touches the slab until a week from now.
Tony, the owner of the block laying company, a third generation mason and character of the first order. Is missing. Tony returns. With enormous Circle K glasses of Gatorade and ice. For EVERYBODY. Tony is the hero of EVERYBODY. I'm thinking, now why didn't I think of that. Then I could be the hero of EVERYBODY. To late now. I'm the owner that wonders around, scowls and picks up rocks (of which there are an infinite supply) and throws them into piles that we are forever moving. The Brain Trust (Ann and Dan) want the rocks. Ann is SWITBO for a reason. So I move rocks of which there are an infinite supply.
Freaking Tony even bought me one. Bastard...
