Thanks Mark,

No, those 6x6 posts support a small deck and roof up above, just outside the dining room.

So far, I've dug most of the trenches, built forms around them, and layed rebars. I 've got more than enough concrete mix to fill them. I'm just waiting for my concrete mixer which I ordered a week ago to get here.

I poured the footings over the weekend. I think I used about a yard of concrete on two separate pourings as I dug pretty deep. I didn't get the mixer yet so it was the old wheelbarrow......good thing I had a friend help me out doing the mixing...

I plan on just dry-stacking, re-barring the blocks, and filling most of the cores with concrete but is it necessary to mortar the first course onto the footings? I need to dead level the first course anyway so using mortar makes sense.

That giant bath tub situation is still up in the air....

"And for extra measure, to prevent eventual sinking or tilting of the slab, I will drive rebars into the existing rear and right side block foundation,"

I would advise against this. Keep the new slab and footings independent of the existing foundation walls. If not, any movement or settlement of the new works could damage the existing walls. Put a 1/2 layer of felt/fiber material against the existing walls prior to pouring.

Hi Neil2,

Thank you for your reply. What you're advising makes a lot of sense. I'm going to rethink this carefully.

More progress. During the week I mortared the first course to the footing and just yesterday I laid horizontal rebars and stacked the rest of the blocks.
I will toss in a few vertical rebars and fill most of the cores this week.

So far, this has been a great practice project for me before moving to the larger patio/WFO project.

Thanks again!

Do you guys think I should fill every core or can I get away with filling every other? I know the cores can use up lots of concrete. Thanks!
