I have a kitchen wall with a window on top, below the window are 8" concrete

I will be installing a kitchen sink and dish washer along that wall, so I
broke the wall on one side to run the 2" PVC pipe to a vent stack to the
right. *The PVC pipe run is over 4 feet long, and in order to run that pipe
and the one below for the dish washer, I had to literally break off one side
of that concrete wall, so that resulted in half the length of that wall
being supported now with just the outside face of the old concrete blocks..

Any idea what is the best way to patch it up? *Do I get 4" thick blocks and
built up the front side? *Do I frame 2x4s to support it? *Do I use ply wood
to cover the front side and pour solid concrete?

Thanks in advance!

MC-

Whether you need to "repair" the wall all depends on the "demand" on
the wall & the remaining "capacity" in the "chopped up" wall.

Keep in mind that my comments come from a guy experienced in wood
framed construction / plywood shear walls / seismic issues.

Being a master of "overkill" I guess I'd rebuild the course of the
wall where the pipes run, with 8" blocks with the "back face" removed
& appropriate cutouts made....

Once the "pipe course" was replaced, I'd continue rebuilding the wall
with 8" block with the back face removed.

Since the original wall appears to have been ungrouted, looks like you
really don't need a solid concrete wall.

I would suggest you estimate the amount of effort to cut & fit the
blocks vs forming up and pouring a solid wall.

Personally I'd prefer to piece it together & build it up out of blocks
rather than work and mess to form & pour. Plus I'm not a huge fan of
encasing pipes in concrete.
