Wide corner with CMU


I'm going to build an island for an outdoor kitchen with 8x8x16 block, but there are a few corners that aren't exactly 135 degrees. Is it ok to just cut two blocks and have them meet at the correct angle? I know that means they'll both be "open" at the spot where they meet, and potentially in each course all the way up the wall.

IF it were mine, i'd alternate the blocks so ea course overlapp'd the 1 beneath,,, that way you'd not have to chance a vertical jnt opening & closing due to temp changes,,, i'd also fill the voids w/grout thereby ' welding ' the wall into 1 unit,,, IF it were mine, that is

I guess that's the question really. How to overlap blocks at a corner that's not 90 degrees. Or even close to 90 degrees. It's not exactly 135 degrees but its in that ballpark. Thanks!

A grinder on concrete blocks is just like a site measured cut on wood and more permanent. A mud joint is the best insurance for minor errors since the tradtional joint can be maintained.

Some block producers (few) make a 45 degree corner for 8" block, but you end up with a quarter bond, which is structurally sound and sometimes architecturally preferred.

Why not cut a bunch of pieces like this? You only need to fill one side, right?

If you want both sides, you could leave the square end in place, and cut the opposite side off short on the inside .... although it still would be weird-looking on the inside

That picture is great. This is going to be the back wall of an outdoor kitchen island. The outside is going to be stuccoed and the inside will be hidden under the countertop. This might be the easiest and strongest way. Thanks!
