I am an interior field person for a large GC in florida.  However, I am now on a job at the begining phases and am fairly lost but learning alot.  Quality control is one of my responsibilities.  You can imagine how difficult that would be for me on a normal building just coming out of the ground, but this is an ICF building and I know NOTHING about this product or how it is installed.  

The links below (if I did it right) are of a corner where one wall is 6" of concrete and the next is 8" of concrete.  Apparently there are no ICF corner blocks made for this application and so they are all cut and then braced with plywood.  Walls are out of plumb everywhere.  I am wondering if this is a major contributor to the problem.

Please take a look.  I would appreciate any helpful comments whatsoever.

Jmcgorty,

We do this all the time (however, installers are not just dying to do it as it requires a bit of skill) -- see futurestone.com Academy at Nola Dunn for photos of this exact corner transition. From and installers view it's not as easy as typical corners etc. however, sounds like you may be working with a less experienced installer. I can tell you it's easy with NUDURA and quite frankly it should not be that difficult given proper blocking (and experience) with a subset of the competitors. Regards.

I guess I'm old school. I started using icf's before there were pre molded corners and still use this metod. Just take the 6" block and the 8" block and make a corner, foam together, make a corner support out of two 2x12's screwed edge to face and screw it to both block faces. Did your picture show corners that had been cut?

smartwall -- you may be old school and I applaude your ingenuity. We often make corners if they are 30 or 88 degrees or whatever, but why make corners when you don't need to? Regards.

Thank you for your replies.  The sales rep for this icf system has offered to visit the site and spend time educating the QC personnel.  I would like to hear what he has to say and am very curious what his opinion will be of the work that's been done so far.  So, I will give him that chance before I continue with any more pictures or questions.  It would be nice if it was soon enough to prevent some fires rather than losing time and money putting them out after the fact.  If he is not able to help, I'll be back.

Thanks again

For future reference, Polycrete Big Block uses no molded corners. The .16 inch steel webbing inside the foam panel provides sufficient structural integrity, so we simply cut back each panel on the inside corner to the appropriate distance with a circular saw and butt them together. In this manner, you can easily transition to different thicknesses of concrete. (By the way, we can make any size cavity from 5" to 12" today, and 16" is coming). 12' tall aluminum corner guides ensure perfectly pumb corners effortlessly. 

Here's a link to the drawing from our technical guide. Finally, Polycrete will never cut you loose on a project without complete technical support and training.

Texas, when a customer orders 28 corners and then digs a walk-out in one corner, he calls an says he needs three more corners I telll lhim he's not building Louis XIV furniture , put two straights on the corner and cut them to fit on the pattern I described. Sometimes it is necessary especially when the job is two hours away.
