NCMA Solutions Center: Is there a special detailing for combining clay & concrete masonry?

Yes. When using clay & concrete masonry in a single wythe, the banding details should account for differential movement (shrinkage of concrete masonry & expansion of clay) of the two materials.  Incorporating horizontal joint reinforcement, vertical control joints, and/or expansion joints are some of the things that can be done to prevent unwanted stress due to shrinkage & expansion that can cause cracking. For more information on banding clay & concrete masonry, see TEK 5-2A Clay and Concrete Masonry Banding Details.
