I'm about to do a 14'-6" high Nudura wall, and I know that this is pushing it!! Reason being: we have a frost wall, the main floor, and the ledger for the second that all needs to be poured as one so that we can form the second and third floors from the floor system (OWWJ, 3/4" plywood, etc.)
Just wondering if anyone on here has any experience with ICF walls @ this height, and would love to hear any tips or stories from past pours. Everything is on a 20"W footing W/ piles underneath, we'll be using a continuous kicker (we usually don't for a 8-9' wall), and 12' ICF braces with small 2x4 extensions. The top row for this pour (one with ledger in it) will be braced from the outside as we have to make room for 2x10 ledgers...
It's going to be interesting, but I think that with about 5 lifts out of the pump truck and some over-bracing we can pull it off.
What  do you think?

How thick is the concrete in the walls? 6", 8", or what? How much rebar is in the walls (vertical and horizontal spacing)? Are you planning on consolidating the concrete internally with a vibrator? If so, do you have one that is long enough?

Should not be a problem----------poured 22' a # of times. Just go through the steps.

If you have a window or door start there. Gravelling can be a problem.

We just poured a wall exactly like that last week without a problem. If you follow what Nudura recommends, you will be fine.

I used Reddi Form which is a screen grid ICF for my tall pour.

We had a building 33 feet to the eave and 45 to gable with a total of 700 lf of wall.

We poured the 33 feet in two lifts from a 61 meter boom truck at the rate of 10yds every 13 minutes.

Our biggest problem was keeping the concrete trucks coming fast enough.

No blow outs and no problems.

Screen grid ICF's are not well understood, but they are fantastic. Saves 33% on the concrete and a lot of time.

And three times the voids

I know of one contractor that poured to a height of 18' with NUDURA with zero problems. Many other people poured to 14-15' with no issues what so ever. Pour slowly and be sure to keep an eye on the wall, but I am sure you will be fine. Very strong block

Just noticed the original date this was posted. Looks like I am little slow on this one - hope the pour went well....
