How have you tied inside to outside plywood?Yes but I placed the Ply inner foundation which is 6” shorter... Should I just leave that 18” tall ply inside the concrete ? Ply B in the illustration?
This is your first foundation?Plumbing is in.... Inner and outer have lots of 1x1’s holding the walls apart . Haven’t packed it yet
I LIKE THAT and it is very commendable... but realistically I think you will find that perfection becomes increasingly important as the job progresses.If I left the inside board there it should be ok wouldn't it? Although I don't know how much I could pack that dirt and keep it in place.
The whole thing is dead on to the `1/16"
You are doing something I have never see before but others like what you have, so I will be watching instead of talking.View attachment 599351 Looking at the link above....Ignore the 2X lumber.
The right panel is 24" and the left 18". Everything left of the panel is the slab which finishes out 6" thick. I still need to add some fill.
So to mono pour I am thinking I have to leave that left panel in, under the slab, to avoid caving.
The project is a 20'X12' foundation
Is this method going to give me problems?
In my neck of the woods it is code.I’ll drill in my anchors when framing ....something wrong with that?
