ICF Inspections
ICF Inspections
(OP)
Hello All, just wondering what others do for ICF inspections. I've never had to provide inspections for ICF walls before...I have a small residential job coming up shortly where it will be required. Its a typical residential job and I am not too concerned with checking every square inch of the wall, but with the potential for larger jobs coming up I would like to set a precedent for my inspections. Obviously the nature of ICF construction restricts complete inspections once the wall is poured. Any input would be appreciated.






RE: ICF Inspections
Has anyone felt the need to check for proper concrete placement behind the ICF once the wall was poured? How do others feel about signing off on the final structure without ever seeing the quality of the finished work?

Infrared thermography can have some relevance to check for proper filling and consolidation, but unless you do something like hook a welding machine to the rebar and force a current through it all to heat it up, it will be difficult to get a good thermal signature....after all it is insulated!

Ron, you raise a good about about continuous supervision during concrete placement. For this particular job, I don't think it is warranted, but something I will keep in mind for larger projects (also, I've already missed my chance for that as the wall is poured). Majority of this project falls under prescriptive codes, and I doubt the City inspectors do anything more than glance at the rebar before concrete placement, if that.
If there were critical areas that I knew were most likely to have issues I suppose I could pull of a portion of the foam and look at the concrete - I just wasn't if that was standard practice among other Engineers.

allgoodnamestaken has a good point about gaps under window bucks and such. I would recommend probing with a very stiff wire probe.

- smoother aggregate in the mix, this made for a nicely flowable and easily pumpable concrete
- Added super-p to the mix as well for same reasons above
- poured and vibrated in 2 ft lifts
- For windows and mechanical openings, two 4"-6" diameter (or square) holes must be made in the bottom sill of the window buck, the first is to pour concrete in, the second is a inspection hole. Fill holes with the piece of insulation that came out of it. I sealed mine in place with spray foam.
And if you go along and hit the plastic ties with a hammer you can tell whether there is concrete or not (as previously mentioned by others)
