FIELD CUT CORNERS

WHEN A MITERED CORNER

IS NEEDED

1) Place a straight block on top of another block

and rotate to the desired angle. Take care to

place plastic ties in a position that will minimize

the amount of cutting.

2) When you are satisﬁed with the positioning mark

both block on the outside faces where they meet.

Notice in the example the block was positioned

so no plastic ties are cut. See Note B.

3) Cut both block and position in the wall. Take care

to ensure the block has been cut so that it does

not force the wall apart. It is better to be a bit

short than too long. See Note A.

4) Once wall is built, stitch and brace the outside

with plywood or dimensional lumber. At this point

some spray foam can be used to ﬁll in any gaps

as long as you have it braced together to keep

the expanding spray foam from pushing

angle apart.

5) Place concrete.

NOTE: Corner will have a very high load of concrete

during placement. Please take the time to brace the

corner properly.

Notes:

A) It is better to be short than it is to be long when

making cuts. If the cuts are short you can always use

spray foam once the wall is completely built, leveled

and plumbed.

B) Plastic ties can be cut if needed as the corner will be

braced with lumber anyway. We just try to not cut

through the plastic because it takes more eort.

C) When cutting remaining rows of block ensure the cut

starts at the same location as the rst row so that

interlock will line up.

D) Use spray foam only after is completely stacked

and prior to placing concrete.

Use screws long enough to pass through the

plastic ties completely. If your screws do not

hold they need to be longer.

Example is a

45 degree angle.
