Providing support while making masonry opening

#1 Post by AliInBaltimore » Wed Aug 26, 2015 12:40 pm

Not sure where exactly to post this question, but here it goes...

I had a mason make an opening for a window in our block foundation. I didn't see him using anything to support the weight above the opening. Also, the lintels weren't installed until the second day; i.e., the opening was left overnight without lintels. I asked him about it and he said something like the existing masonry has cured so leaving it like that for just a day shouldn't matter. The work looks great, but I was curious if in the future I should be more careful about this sort of thing. Thanks for any thougts.

Unless the wall is compromised, nothing is moving around in a 12-24 hour period.

Thanks. (I changed the picture to a better one of just the masonry opening without the window.)

Most homes are built with Bond Beams intermittently in the walls. This will stop most of the sagging or smiling as we call it. I'm a big supporter of Lintel Irons being applied during the resizing or cutting. Some guys will wait so they can cut the joints. I like them installed during the bricking process. This way they can be seen easily by any over bearing inspectors who show up unannounced!

yep, that opening looks great.
rebar reinforced concrete lintels.
