| I am ready to pour or I think I am .I am working on my first ICF project[my own house addition] and would appricate any last minute advice before I pour. The pour would be the basement walls of a two story addition with ICF's up to the roof line. I am using IceBlock ICF's. The walls will be poured 18" above the first floor line. I have the forms and steel in place and am finishing up the bracing which will be approx 10 feet apart. Is this sufficent bracing? I am going to be pouring using a small concrete pump with a 2 1/2 " hose. The manufactuor says to pour 4 feet tall all around and then go back to the starting point and add another 4 feet on top. Is there sufficent time for the concrete to set before the next layer is added? I am afraid of blow outs if the first layer is not sufficently set, how does one know? I am a carpenter by trade and do have some concrete experiance with the old plywood forms. Based on my memory I remember alot more bracing and we poured concrete full height as we went along. All of the people pouring have little concrete experince, I am calling in my favors, so what would be the best use of manpower? One last question, how do you deal with the nay sayers? Since this is the first ICF project that I know of in the area[Long Island New York]the amount of negative comments has been overwhelming. Why don't you just use wood,you don't have any experiance with the product, you lose alot of room with thick walls,etc,etc, Any last minute suggestions before p-day [pour day] Thanks Philip Simon |

Philip:
10' apart, for a novice, does sound like a bit of a span for the bracing, we use 4-5 foot centers, and have a bit of expierience in waffle grids. Have you checked for all of your utility penetrations, squareness of building, and arranged for a couple of extra hands to show up during the pour? Philip, I spoke with Larry Simon prior to his pour, and he has explained that it was a big help. You can also call me at any time (number on website, I am in Ohio office). Ian also often helps with advice via phone, and his US expierience far outweighs mine, he is a good source for information as well. I would highly recommend the 15 minutes or so to talk to someone on this.

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.
