Clay, Take a look at the pictures provided. That is the end of the R-5 hangars (closest to Addison Road) where IAM poured concrete. As you can see, I don’t think they put any sort of joint between the existing concrete and the new concrete and it looks like its shoving and cracking. Do we have any sort if active warranty with them anymore? Joseph McAnally Operations Manager Addison Airport (972) 392-4861
