I have been asking alot of questions regarding some new partition walls I
have put up in my basement. I appreciate all the advice; even if I didn't
follow all of it.
I bought a tool at a garage sale that is supposed to let you hammer special
nails into concrete. I thought I would use it to anchor the bottom plates
to the floor. You get what you paid for... the nails just bend up. Oh
Well it is Sunday night, with no stores open, and I just can't leave thing
undone; so I figured I would make do with what I had. I drilled a 3" hole
through the bottom plate and into the floor. I mixed up some laminating
epoxy, poured some down the hole and coated a 3" bolt. Then I hammered the
bolt down. I know they use glue-in bolts on rock climbing routes, and this
is a rather less critical application. Ought to be good enough, wouldn't
you think? (Why didn't I ask about it BEFORE doing it? Donno.)
The concrete drilled alot easier than I expected, but I had a problem
getting the dust out. I duct-taped a straw to my shop-vac and that seemed
What is the proper way?
just fine. the stress is sideways on these bolts and they would
hold even if they weren't glued. naturally, solid is better tho.
i think the pros use a nail gun, or srill holes and bang a
concrete nail in. i'd be awful surprised if anybody
actually used bolts.
Sleep well, you've overkilled the daylights out this one.
Chemical anchors (epoxy adhesive) are the top of the line, state
of the art, cutting edge method of setting anchors in concrete.
Your application sure did not need it, but better safe than sorry.
Here is some more information:

There is more than one way to skin a cat! Epoxying in bolts is
overkill, but what the heck. Some other options are "tapcons" which
are specially designed screws which drill into concrete (you have to
drill a pilot hole first!), regular expansion bolts, rawl anchors (a
nail-like pin with a bump in it that wedges into a hole drilled into
concrete. You can even drill a 1/4" hole and pound in 2 16 penny
nails. Or, in cases where the concrete isn't drillable, you can use
construction adhesive to glue the bottom plate down. These are
non-load bearing partitions, mind you. If you are dealing with load
bearing walls, especially in a seismic zone, you will want to consult
your building inspector or other expert.
