Masonry Wall Design: Single-Wythe
Moisture penetration through exterior walls is a concern on every project (or – it should be a concern on every project!). Single-wythe concrete block construction does a great job in preventing water from entering the interior of your building but there are several important “belts and suspenders” that should be included in your design to make sure your masonry wall does the best job possible.
So, what do we consider a single-wythe wall? There are three major types of masonry walls built in Florida. The very best masonry wall to prevent water passage (we call it The World’s Best Wall!!) is called a double-wythe cavity wall and contains a drainage/air space between two separate wythes or “layers” of masonry. Water that makes it through the first wythe runs down the back side of the wall and is discharged to the exterior through flashing and weeps.

When my daughters were in high school, they went to a school that had a “Six Inch Rule”. Boys and girls had a 6” rule of separation. Now, as most of you fathers of daughters know, six inches is simply not enough!
A distance that can be critical for a masonry contractor is the distance from which masonry should be viewed to determine its acceptability. If we have reached the point of trying to view the masonry from a certain distance, we already have a problem.

What can I do about congestion? The short answer is take an anti-histamine and call your doctor. Oh, not that type of congestion! That’s a sinus problem and all in your head anyway!
Congestion in a concrete masonry unit (CMU) wall creates frustration and aggravation for the mason. This leads to lower productivity and the possibility of mistakes by actions or omissions. Add it all together and you have created the potential for a less than expected quality product.
“Congested” is defined as something being too full or overcrowded. There are several ways that CMU wall can suffer from congestion. The main contributors to the clutter in the CMU wall are the mechanical, electrical, and plumbing trades. Masonry is the only one of the three major wall types that is expected to accommodate their “stuff” as we build the wall. Wood and stud walls are built and then the MEP folks do their rough install. On the other hand, we (masonry) are expected to install piping, boxes, conduit, holes for duct work, etc. the accumulation of these things created congestion.
