To existing house with a crawl space from concrete all around, there is added (later on), as we call it, extension room which is around 8×8 ft and laid on 5 piers circa 18 inch above the ground.
I will ruin existing “extension room” and make another one 9×12 ft, more solid and better insulated.
-My biggest issue is footing and foundation.
-no way to get truck-mixer
-I prefer to make wall instead of piers 12 ft away from house
-concrete wall is 1.6 cubic meter, so way too big for 2-bag electric mixer
-concrete MUST be made with 2-bag electric mixer, so must invent something
-one or two persons available
WAIT DO NOT RUN
-to make a wall I have to invent a new way to make concrete foundation, so here it is:
1. pour footing 16 in wide and 12” height, let it cure, which can be done with small mixer
2. make fence for foundation 26 in height (vertically), and partition it by vertical plywood walls in 10 sections so each section is 144/10=14.4”
3. pour the first section at top of footing and remove first plywood fence, pour second section and remove second fence, …
4. I got 10 piers adjacent to each other.
5. all piers are interconnected by dense distributed rebars (lots of them) to prevent that any piers move itself
6. put pins at top of each pier.
7. pour rest 12” height wall on top of 10 piers as one strip. This will also keep all piers not to move. So piers are locked at bottom, top, and rebars through all piers.
Am I getting patent from you?
Or
Might be piers will be better choice.
House is at North side of Lake Huron – Canada (Great Lakes zone).

Wouldn't it be simpler to use ICFs, which would both reduce your concrete requirement and make it easier to do multiple pours?
(Good luck on the patent. I have 13, and all of them involved much more "invention" than splitting a pour like that.)
Thank you Dan for reading about my problem. I just joke about the pattent, but have to invent something above what is known to me so i can use my little concrete mixer. By the way i am mechanical eng. so everithing in construction is new to me. I know what is ICF (foam wall-insulation) but how it can make me possible multiple pour. Can you please be more specific?
Do you think that my plan with multiple pour can work, and is it better than to make 3 piers 12" dia at 6 ft distance between piers?
Thank you
So what is the reason you can't get a mixer truck?
There was an interesting post by Brownbag on another forum that talked about how DIY concrete in your little mixers will not have the same strength as truck mixed... something about air entrainment, don't remember.
truck is not available in the region

That concrete strength is higher when pour is made by truck than when it is made by hand can be long story.
Concrete truck is a business and concrete they deliver is JUST ENOUGH quality and strength, otherwise the trucker is out of business soon because of high expenses and competitions. He always look to make money before make a concrete.
Making concrete by hand people mostly want to spare money so they buy cheat and not good enough. Add to this fact that concrete made by small mixer is too slow pour, so cracks comes.
But some make it by hand because they want more than truck offer and who can make me sure he added air entrainer e.g. 8% but not 4%. How I can know he did not use the cheapest available cement for the mix?
Especially in North Canada, air entrainer is a must if one want to avoid scalling of the concrete.
Hand made concrete is normally much better than truck ever can deliver just because one can closely and surely control the content of the mix and components quality too. The only problem is that hand made concret is slow pouring so no large project is possible, as house foundation is, withuot several electric mixers and around 5 guys. This can jack up the price to heaven.
Now it is why I am looking for a way to pour slowly and still make it good. This invention will be nothing short to invention of personal computer.
You've got a big opinion of yourself for an "invention" that's not much different from what I saw used in Mexico 15 years ago (and which I presume was used for decades before that).
(And, in a not-insignificant way, I helped invent the personal computer.)

Was that as part of the potatoe VP's or the global warming VP guy's teams ?

If the system is in use that means it will be OK to go? Am I right?
Sorry guys did not want to bother you. Patent is just a joke to make it all non-formal.
It worked, in Mexico, on caliche soil which is quite stable in that climate. And these guys knew what they were doing.
Building technology is changing so quick. New kind of concentrate, new solution everyday. For me ur idea is fine and it should work, at least it's worth trying. http://usedconstructionmachinery.blogspot.com/
