How to secure half wall to concrete floor.

As you tighten the nut it draws the bolt upward and spreads the anchor out which makes a very tight fit in the concrete. Other nails have a thick shank that sometimes has spiral ridges for improved holding power. If the floor is less than four years old drive specially hardened masonry nails through the bottom plate into the concrete. One half inch of penetration prevents shifting so drive 2 inch nails.

The idea is to drill a hole in the cement then drive these down. Be sure to wear safety goggles when hammering masonry nails into concrete. Setting up a wall on a concrete floor presents a bigger challenge than merely nailing into a wood subfloor. Fortunately there are plenty of solutions.

One method that works extremely well if the floor joists and half wall line up to install 1 2 plywood over the wall and down past the subfloor and onto the floor joist. Another method is to run the half wall 4 4 outer post down into the framing and to bolt it to a joist or similar blocking and use 2 1 2 through bolts to attach 4 4. They can be used in concrete block and brick. I m using 3 8 diameter bolts that are 3 long.

In this video i show you the method that i use to attach basement framing to a concrete floor. I use tapcon concrete screws to secure the wood to the floor. Concrete screws come in 3 16 and 1 4 inch diameter in lengths up to 3 3 4 inches.
