How to Stud Walls to Garage Floors

Updated February 21, 2017

If you want to make more out of your garage than a big empty space, you may consider adding walls to the interior so the space can be divided. The best method for doing this is to construct stud walls and fasten them to the floor. One difficulty with approaching the task in this manner is that most garages have concrete floors, which can make fastening the wall to the floor difficult. You'll need to use the right tools and techniques to make a solid connection.

Drill 1/4-inch holes, spaced 8 inches from each vertical member, in the bottom plate 2-by-4 board of the stud wall.

Raise the wall and manoeuvre the wall into the intended position with the help of an assistant. Mark the location of each hole on the floor below the wall with a piece of chalk. Lower the wall and place it out of the way.

Drill 2-inch holes at each chalk mark with an impact drill. Place a masonry anchor into each hole and tap them completely in with a hammer.

Lift and manoeuvre the wall into position. Place a lag bolt into the first hole and screw it into the masonry anchor with a socket and wrench.

Place a shim between the top plate and the ceiling joist on the wall above the first lag bolt. Drive a nail through the top plate and shim and into the joist from the bottom side of the top plate.

Continue down the length of the wall, insert and tightening lag bolts, then shimming the top, until the wall is completely fastened in place.


Wear eye protection when working with power tools.
