how high can you go with an icf wall before you should split the poor into two different pour days.  i.e on a 15 foot wall, pooring 6 ft first, waiting a day, then pouring the other 9 feet, or if you had the right scaffolding, could you pour all 15 feet at the same time, @ 4 ft passes?

All the same day using 4" lifts around ought to do the trick.

if you have the proper height scaff. do it in one pour at the 4ft., or less, intervals. the problem with pouring one wall in two different days is that you can end up with a 'crease' in the wall where the first pour stopped and the second one started. If you don't have the first pour perfectly straight and plumb, that can happen. Do in in the one pour, use extra braces if you have them, and take your time. I have done many gable ends that are around 15-16 feet high with no problem!!

we do 20 foot walls regulary with no scafolding at all. :) and yep all in one day. 4 foot lifts. and our crews avg around 30-40 cubic foot and hour. :) they have done more on thicker core walls like 6 inch core or more.

 

 

Not to hijack the thread but how would you handle a 2 story tall living room walls. The walls are about 20 ft high, rest of the house has 10 ft walls on the first floor and 8'4" on the second.

CFL-ICF,

How do you get the hose and man up on a 20' wall without scaffolding?

 

Thanks,

NLC; pour heights are strictly mandated by the block you use and the slump you pour, along with your experience and comfort level. We have many customers that pour 18' in one pour, at lifts of 6' to 10' which are mandated by there level of experience.

Esperience will always dictate how comfortable one can go up but the block.  ICF block, bracing and ACI standards dictate  as well.   ACI, as previously stated in this thread, calls for no more than a 4 ft. lift an hour.   Have we done more, sure.  Do we teach others to do this, no.
