| Specifically, can it be used successfully to pour a stepped foundation, with the downhill part four blocks high? |

| Go to Fab-Form web site. Projects, down to father and 2 sons section, it shows a multiple step footing with fast foot. |

I am very sorry I incorrectly stated my question. I want to hear from those who have done the monopour method, ICF block AND fastfoot formed footing beneath, the pour doing 3-1/2 blocks depth at deepest, and 1/2 block high at highest.
What we would like to do, and we have done ICF work before, is do a stepped footing foundation whereby we pour walls up high enough to be then able to do the backfill of stepped parts and stemwalls, then do the basement floor slab, then work off the slab to do the rest of the build. |

| We've done a few. The only thing that is different from a normal step footing pour is the block-out at the end of the footing form. We use galvanized sheet metal to block the ends of the footings because whatever you use become part of the foundation |

2 things come to mind. Usually the step increment is 2', it could be more, however, 3.5 blocks is +/- 56", and that is a lot.
But a bigger issue is if you attempt to place that much concrete above a fabric footing, you may not be able to pour slooooooow... enough for the fabric to stay attached to the 2xs. You may be able to cap the footing, but the amount and timing will still be an issue.
If the project is large enough, you may be able to pour the deepest footing first, and get enough set-up time; the other choice is to use a faster setting mix. Discuss this possibility with the ready mix supplier. |

| Our normal step height is 4' for walk out basements. I have a customer doing one next week. |
