Does anyone know the name of the CMU type that has a section of the block missing on one side to allow forming before pumping with grout? (unable to pump from the top.)
Please explain how you pasted the block pictures in your message - it is really COOL! (Cool: a word in use during the decade of the 1950's meaning neato, keen, crazy man, out-a-sight, its-the-bomb)
Wow! Images are what's been missing all along. I have ignored some postings because without a picture I was not sure what was being asked. You have broken new ground here.
