bhapgood Posted January 3, 2014 Report Share Posted January 3, 2014 our nonprofit completed a building 3 years ago. There are exterior wall redstone blocks that are moving out from the building. One of them is at the corner above the pergola, 3rd row from the top. The other is straight up from the entry sidewalk on the 2nd row from the top. The one on the corner has moved out about an inch and the other one has moved about 3/4 of an inch. I believe water is working in through bad mortar joints and freeze/thaw action is pushing them out. I don't know for sure it is just my theory at this point. Pics included. We are trying to figure out how to fix the root cause instead of just the symptoms. Anyone recommend someone to advise us in Colorado (near Glenwood Springs)? Click to Enlarge 30.04 KB Click to Enlarge 38.47 KB Quote Link to comment Share on other sites More sharing options...

kurt Posted January 3, 2014 Report Share Posted January 3, 2014 No coping. It's running water, look at the white stains in the first pic. Call Garet Denise Cornerstone Building Inspection. Quote Link to comment Share on other sites More sharing options...
Scottpat Posted January 3, 2014 Report Share Posted January 3, 2014 I agree with Kurt... It also looks like the mortar is cracking in several areas in the first photo. Garet would be the one to call to take a look and figure it out. Quote Link to comment Share on other sites More sharing options...

Garet Posted January 6, 2014 Report Share Posted January 6, 2014 bhapgood, Congratulations, you've already figured out what lots of builders refuse to believe: 1) water can enter masonry construction and 2) freezing water causes damage. I'd be happy to help, but with a 3 hour drive each way that would be an all-day job for me. For that much money you could probably just have a competent roofer install coping over the top of the walls to keep water out. Quote Link to comment Share on other sites More sharing options...
