I have a shop with concrete foundation. I am planning to build a little office where one wall is against and secured into current shop wall.
In that case, do I still need to bolt the other 3 wall bottom plates into the concrete foundation? My concern is the potential crack in the future if I use power actuated gun.
The office is 10’x30’ dimension.
If you mean just set it on the floor and use pressure to hold the bottom of the wall in place? No I would not even consider that. It needs to be held in place in some manner.
Concrete screws will work be considerate of the length you use. They are made to go only 1 1/4" into the concrete. Usually any longer than that, they will shear off and do you no good.
Drive pins work really well, strong and pretty much fool proof. Drill a 1/4" dia. hole and drive them in. One at each end of every plate, 4 ft max in between. I place them in every other stud bay myself.
