Thansk for showing in details this process! I am carpentry-framing student and we just finished the concrete foundation module. This is a great visualisation/recap of the prep/pouring process!
For what it’s worth… I’ve never used bag form, but I have had a lot of luck with this visqueen. The concrete cures a little slower, stays hydrated, a little better, so in theory it’s a little stronger and wicks less water.
Hi Steve, I am going to use "Fast Footer" with a stepped footing, for a slab floor on one side and a full basement of the other side and also for I.C.F.'s in the State of Maine, Liked#37 N Subscribed!!!
The fabric form is a cost savings feature as well in that it reduces labor needed for stripping and handling of form materials. It’s just abandoned in place after use.
Steve, Is it common for the electrical service grounding wire to be installed in the footing in residential construction as shown in your video? I know it happens in commercial buildings.
Very interesting product. I had a custom footing company many years ago and I would have loved to try this fabric form system. Seems like it would lessen the wear and tear on the basic 2x forms for sure. Great details with the rebar.
Depth of footing usually is a function of frost line to protect against heaving if the ground freezes. In the north part of the country clearly has to be deeper than in say Arizona where the frost line is very shallow. Clearly you also want to consult and engineer. Seem like they were using #3 rebar for the vertical segments. seems a little light since you'd think they will be using #4 for the vertical rebars in the wall. Usually 3" is the minimum coverage of concrete around rebar, seems a little thin with those chairs, but the height of the chairs wasn't disclosed. Especially with the J verticals UNDER the horizontal rebar in the footing. Regardless, My guess is the footing when mated with a huge concrete wall isn't going anywhere.....
Never move fresh concrete with the viborator and don’t let the concrete flow down the footing to a lower level. It is called aggregate segregation. Use the pump to place the concrete directly, that is why it is there.
Dang Steve I've detailed that J bar for so long i no longer rememered why it was there. I've never seen a detail about alternating their direction either. Thanks. Now i need to update all my details.
If you ever do any detail drawings for the engineering in a building, you're likely to see that alternating J-bar detail a lot. I still remember the days when they would call for a keyway instead of rebar verts! Ha
From my understanding, the Fast Foot product primarily allows the waterproofing of the perimeter foundation of a structure. Assuming the use of ICF, they will set upon that smooth, leveled footing surface? Fast Form also offers a supporting "foot" of sorts that will allow the installation of some ICF forms as part of the footing pour, I think. A snazzy system.
It's most often used to provide an earth connection for lightning protection systems, but it can also be the earthing system for the home's electrical installation. Rather than drive a single earth rod into the ground where it is subject to corrosion, the connection to the earth is made via the rebar and concrete footings over a large area. This protects the connection, and generally gives a better connection to earth. I do wonder though whether the plastic used to construct the forms is somewhat insulative and so negates the benefits. Googer Ufer grounding systems for more info.
The pipe is laid outside the footer and covered in gravel and filter cloth. You want to keep the clay soil far from your foundation because it holds water for a long time. Gravel and sand will allow the foundation to drain and shed moisture from the floor and walls.

That's a great idea and a capillary break for the masonry. The less moisture masonry can wick the better.

Really appreciate seeing these details and the pour Steve!

Recording in verticle mode with no FS expansion makes it almost unwatchable for me. JS

In MA it's required I'm told
Yea I saw that and was curious about it too

Beat me to mentioning that.
These are supposedly professionals but that's sure not.

Have a question? Why copper wire tied to the rebar?
I have the same question. @9:39

@@tlangdon12 Thanks for the info. You bring up a good question about the plastic being an insulator.
Good details
Steve, It looks like the video topic label got misspelled. FROMED vs Formed
wow cool
One more question: where is a pipe for water mitigation?
That would go on the outside of the footer after the forms come off.
The pipe is laid outside the footer and covered in gravel and filter cloth. You want to keep the clay soil far from your foundation because it holds water for a long time. Gravel and sand will allow the foundation to drain and shed moisture from the floor and walls.
Uh, i hate portrait video.
Another cool video. What is the copper cable running along the rebar for?
Electrical grounding for the building.
