Does anyone know a good calculator for figuring out the length, width, height of a concrete block wall with mortar? I haven't been able to find one and so far not having any luck.

I'm just basicly wanting something that can calculate the number of blocks and show the final LxWxH of a wall with X number of rows of block based off standard block sizes, I'm planning on using 8 in thick blocks. I don't want to cut any blocks at corners, so just need to know what they'll naturally end up being taking into account the mortar. I'm going to be ordering pre-cut metal sheeting to go around the outside of the wall and don't want to worry about having to trim of 1/2 inch of metal around a 12 x 12 x 9 ft square.

Thanks

Buy corner blocks.






Just buy them



Thays all I have to say about that
 
Mortar is usually 3/8” to 1/2” and I believe CMU’s are exact dimensions (not like lumber). So every block is essentially 8.5” high and 16.5” wide when accounting for mortar.

You’re not going to bulls eye a measurement, especially if you’re not an experienced mason. It looks easy on YouTube, but it’s not easy to nail it. And it sound like you’re aiming to nail it.

I’ve never worked with metal sheeting for a siding, so I don’t know if it’s like any other siding. My guess is it is, so you need an air gap between the block and siding. Remember to account for that.

I appreciate the advice and help.

I'm building a metal building for a workshop and inside of that I'm building an office space, restroom and a gun room/storm shelter. I'm going to have 1/2 height liner panels along the inside walls of the building and order enough liner panels to trim the outside of the office area. I'm worried about how the blocks will line up with the metal panels. I'm planning on covering over the gunroom/shelter with 3/4 flooring along with the top of the office/bathroom. I know I can always just cut the wood parts to length so that the flooring over the wood framed office and the gunroom are flush with one another. The metal is what I'm worried about the not lining up.

Maybe I could just order some kind of L shaped trim piece to go around the outside and not have to worry about it? I was worried about it being a possible cutting hazard antime I was working around the edges, but I'm planning on installing railing around the edge anyway so once that's up I wouldn't be able to get to it anyway.

As far as the air gap the building company said they have plastic pieces that match the pattern on the panel, you fasten those pieces to the outside of the office space at the top, middle and bottom and then fasten the panels to them. They said they have people use them all the time for that but that most people leave the top of the rafters open and either blow in insulation or lay in roll type and run their wiring in from the top just laying it across the rafters. I'll hit them up and see if they have a trim piece that will work, thinking it through I'd be surprised if they didn't since they said they had trim for a door or window.
