cmu course layout???

You are right about the poor Wisconsin availability and creativity when it comes to block. Almost as bad as Florida and some other southern and eastern areas with a lot of unexposed concrete masonry. There are still some good architectural block made in Wisconsin.

In Minnesota, the cheap houses and townhouse development basements have gone to poured, but the better quality and larger homes are still block in the basements. Of course, the colored, architectural market percentage is still good.

We carry a lot of specials, but we also charge a premium for them. For example a 8x8x12 3/4 block(2 core) or 12x8x8 1/2 block(1 core), costs $1.56 VS $1.35 for an 8x8x16. DYI'ers often complain about this, but the reality is that specials are run once or twice a year and have to be stored until sold. That is why they cost more.

Personally, I cringe when I see anything smaller than 4" in the wall with brick, and 8" with CMU.

Don' know why ya wanna knock Florida block foundations.... Here's one my brother-in-law ran up yesterday. The mortar didn't arrive with the blocks, so he figured he'd just pour it as a dry stack.

I may have worded what I wanted to say wrong. I know that there are thousands of different block made. Varying length, height, width, textures, and so on. Around here we cut our block. If you need a 14" piece then you cut a 14" piece. In this area the corner/intersection straps are not used that often. Also most times an intersecting wall is not physically tied. Wall ties are left hanging out of the wall and the intersecting wall butts up to it. I know the use of pieces and how to tie walls/ corners together. But to order factory pieces for something (unless a job calls for a thousand of them) is pointless. Unless it is something you use all the time like a factory half.

The reason the mortar was not there is because the block he ordered were simple interlocking block that actually can give you lower strength than conventional block with mortar (whether you grout them or not). Obviously he was not planning on a head joint and the block with a recess for the bond beam are weaker when used in the rest of the wall that is not filled. - Just a way to minimize productions costs, but possibly good enough for the type of construction.

If you look at the block and the way they sit on the pallet, there is probably poor height control in manufacture that can be acceptable only if the walls use mortar and are covered.

Florida has some big producers, but is geared for a different type of construction that requires more strength in the CMU and better height control where exposed masonry is more common.

In Minnesota, the basement contractor are more critical than the commercial mason contractor that do only buried commercial work. A basement contractor orders and pays for the block and can do a job better and faster if the buys better block than the cheap stuff.

Florida has improved since I first wandered through the plants 30-40 years ago (when they only made 8 or 10 different block), but is still geared for minimal shapes avaialable for covered construction.

T'was a joke, Dick. One of my brothers-in-law is a lawyer, and the other owns a chain of fast food restaurants. Although a few of my masons might lay up a foundation that could resemble that pile on the pallet.

We too cut 98% of the time. And I see nothing wrong with it. But Florida lives with continually tightening codes, and more than a few communities now get very anal about "textbook" blockwork... as well as just about any other structural trade.

Some even insist that we use those "factory" rebar inspection blocks that come with a package of those silly little filler pads... as opposed to simply cutting our own.

And God forbid you get caught sticking a little filler piece in somewhere.

Hi Willie,

I like your graphic presentation for the CMU layouts on the first page.
Did you create these using Sketchup?
