hausdok Posted April 19, 2011 Report Share Posted April 19, 2011 Couple questions for you brethren that have worked lots of masonry. Large house - nearly $1M - 10 years old. They used real stone cladding on the lower part of the front walls. There aren't any steel lintels and it looks like the stonework might be resting on a masonry ledge with an overhang of about an inch and a half. There isn't any evidence of weeps or flashings at the base of the veneer. I examined and scanned the interior walls very closely for any hint of moisture intrusion and saw none. The base of these walls is pretty thick, so I intially thought that the foundation extended the full height of this stonework and that the veneer is fully grouted and mortared directly to the face of the concrete; however, after checking the tax assessor's site I think I was wrong. The only photo in the tax file is a fuzzy black and white of the front of the house. It shows that at the time the photo was taken the EIFS lamina had already been applied and that the front stoop and the stonework were not yet completed. One can clearly see in the photo that the lower part of the walls is covered with what looks like a layer of black building paper. I suppose it could be a coating of waterproofing over concrete but one can see where it looks like they still had a piece of paper to apply at the corner of the garage when the picture was taken. It's hard to tell whether the stonework is being installed on top of a concrete shelf or is being applied lick-n-stick fashion the way that faux stone veneer is installed. I think that because of the average thickness of this stone and the fact that I can't see any wire lath, that it's resting on the ledge with some overhang and they simply did so without any weeps or flashings. It's a tough nut though. Wish the photos were better or I'd had as-builts on-site like I normallys see when I do these high end homes. I thought I'd pass it by the brethren to see whether folks concur. The second photo below gives you an idea of the average thickness of this stonework (Please don't comment on the cracking, I've got that handled.), the third shows a section of the wall and the fourth shows the bottom of the stonework where it overhangs the edge of the foundation. No sign of any weeps or through-wall flashings and it looks like they might have had a 2 by 4 against the face of the ledge as the stones were mortared in place. Mike, you're a former mason; Kurt, you live for masonry and Bill, you've seen this stuff when it's been a couple of hundred years old. In addition to the lack of flashings and weeps and the issues that can cause, are you guys seeing anything else here that I need to be concerned about? ONE TEAM - ONE FIGHT!!!
