Masonry Wall Expansion Joints
Masonry Wall Expansion Joints
(OP)
I have a building that is 117' long with a 8" CMU wall that extends 12' AFF to a bond beam and a pre-engineered building above that. I am locating joints in the CMU wall and wondered if the joint should extend down to the footer? The foundation wall is also CMU and is just down to frost depth that is around 30" below grade. It seems to me that it should but I continually get into disagreements with others that don't think it needs to. Which should it be?
Thanks
Thanks






RE: Masonry Wall Expansion Joints
For concrete based block (i.e. CMU) they are control joints - not expansion joints.
Concrete block shrinks.
