Can I use wafer board when I form up for my garage stem wall?

Doesn't sound like a good idea...Never seen it done...I'd spring for the
extra few bucks for plywood...

No- it wicks like a sponge, and has *no* strength- by the time you're
done bracing it you might as well have used 2x lumber.

Use 2x12's & decking screws. When you're done you have some great
shelving for your garage. A quick coat of oil & it comes cleans
up real quick.

Do you mean OSB? If so it will work but the pattern will telegraph to
the surface of the concrete. As long as it is below grade or you parge
it won't be a problem.


I hadn't heard of parging. In my area perhaps it is referred to as sacking?
I don't plan on parging. The OSB board has two surfaces. One side you can
see the chips. The other side has sort of a texture. I was thinking of
using the texture side. I would spray with concrete cure before I poured.

I used two inch lumber for my last foundation 20 years ago. They fastened
together with metal straps and wedges. The lumber got reused in the floor
of the house. No one does it this way any more locally. I can't buy the
straps anymore. I still have some wedges left. There also is no way to
reuse the lumber in this project though I have a lot of used 2X6's
available. Now they appear to use 3/4 plywood and metal clips at the top
and bottom. I could reuse the plywood to make cupbards inside the garage
later. I thought I could reuse the wafer board. If it can't be reused it
is so cheap I wouldn't care.

I'm w/ Jim. You didn't give any clue as to the size of the pour, but
unless it's tiny the lack of strength will either entail such an excess
of bracing you might as well have used all bracing material or you'll
end up w/ a bowed pour or worst of all, it'll blow out...

I'd follow the lead you outlined above or use the tubasickses you got on
hand if had enough for the job...

Pat, it is sad when people answer that don't know what they are
talking about. The OSB is plenty strong enough, though most
contractors stay with 3/4 BB plyform because you get more pours
out of it. I don't know that I would use OSB with the stem wall
clips, I just haven't used them. Contact the fellas at Ellis for
an answer. I'm old enough to have formed and poured plenty of
walls with 1x material, I've never seen commercial wall work done
with 2x.

Do not put curing compound on the forms. Yes, do put form release
oil on the forms (avoid getting it all over the rebar). Use the
waxy side of the OSB against the concrete and don't worry about
form release, though I would probably use it anyway.

If the walls are above 24", the forms require whalers and stiff
backs or you can create wood framed pan forms. You must have a
source for snap ties and camlocks in your area (some use button
head ties and wedge or Jahn clamps)

But OSB bending moment is only about half that of Doug fir ply from data
from Canadian plywood association.

Whether it's "stiff enough" depends on how well braced and how much a
pour, neither of which was provided. There's no doubt at all it'll take
more bracing to maintain the same form straightness w/ OSB as compared
to ply.

If you don't believe it, look up the bending moments data yourself...

This post helped. I learned Lowes is not the place to shop. I am thinking
of using 3/4 plywood and reuse it for cupboards inside the garage. I like
the looks of Jahn clamps and using a 2x4 whaler near the top and nailing the
bottom of the plywood to a 2x6 fastened to the footing. Masco.net appears
to be about 20 miles from me.
