When finishing a basement one of
the most common questions asked is how to attach framed walls to concrete
floors. There are three common methods that I have used.
The method I prefer to use most
for attaching framed walls to concrete floors is to use a hammer drill and
Tapcon screws. I simply drill a hole through the bottom plate of the framed
wall, and into the concrete the necessary depth for the particular Tapcon
screw that I am using. Typically I use a 2-3/4 inch Tapcon screw. |
Another method for attaching framed walls to concrete floors is to use a powder
actuated tool. A powder actuated tool can quickly drive a concrete nail through
the bottom plate into the concrete floor. A powder actuated tool / nail gun
typically uses a 0.22 or 0.27 caliber shot load explosive.

The third alternative for attaching
framed walls to concrete floors is to use concrete nails with a framing hammer.
In my experience this method is the least accurate as the concrete nails
sometime wander from the desired locations, thus causing the wall not to be
perfectly positioned.
When framing basement walls, I
normally stick build them. Unlike framing a home or home addition, there are
inconsistent heights in a basement due to the concrete slab and deflections in
the various overhead floor joists.
|
Consequently, I fasten the bottom
plate of the framed wall to the concrete floor first. I then install the top
plate to the overhead floor joists, and finally I attach the vertical stud
members in-between the plates.
When attaching the bottom plate to
the concrete floor, I first apply a bead of liquid nails to the underside of it.
I then put it in position and attach it to the concrete floor via one of the
three methods described above.
