Philip, can't seem to reply, so had to start a new topic
Philip, I just completed my first pour with icf's. I used a flat block vs the waffle type you are using. I braced at 4 to 5' intervals along straight walls and at all corners. The waffle type forms may require less bracing, I'm not sure, but I would be very nervous with bracing at 10 foot intervals. I spoke with several people, including Mark Ross. You can learn alot over the phone in 10 minutes, I think it would be worth you time to contact Mark or someone with experience with icf's.
It sounds to me like you're pour is very similar to mine. I also poured about a foot or so above the floor line. Here are a few things I would look/check for:
1). How are you installing you're ledger board? Make sure your pour is high enough to cover bolts by atleast 5" or so.
2.) Tape the top of the top row of blocks so concrete wont get in the grooves/teeth of the block. It's not fun cleaning every tooth/groove with a screwdriver.
3.) Since you're pouring above your floor, Mark all door openings and MAKE SURE you don't put concrete in this area, otherwise you'll be renting a concrete saw to cut it out.
4.) If you have any short offsets, brace them well!
5.) Make sure you have rebar on hand to set so that you're second pour has something to bond to.
6.) Make sure all holes are plumbed. I plumbed for everything I could think of and then I Added several more for the heck of it. I can fill them in if I dont use them.
7.)If your ledger board is already attached, hopefully it will remain relatively level through the pour.(next time I'll set the bolds then attach the ledger board later).
8.) Ask the cement guy to stick around for a few minutes if he can. You can use his hose to spray off the walls. They may get kind of ugly during the pour.
9) I had 5 guys on my pour, I wouldn't have wanted any less. Mark Ross told me that I would be very busy after the pour was complete and he was correct. You'll need to set re-bar and/or anchor bolts, make sure the walls are plumb, clean the walls, screed the window openings, and a bunch of other little things.
My first pour went very well. I had no blow-outs. I had re-plumb a few walls. I had several 2 foot offsets. At the very bottom of the wall where the pressure is the greatest, the wall pushed out about a 1/4 inch, the top of the wall was o.k., so brace those types of corners well.
I know polysteel is a different type of block than what I used, so it may react differently in the same circumstances.
Keep in mind that I am just a rookie. I've been on a dozen or so pours, but I've actually poured only one myself.
Remember, good preparation usually brings good luck!
Hope this helped.
If you have any questions feel free to call.
