Stud Walls On Concrete Slab

Or you can leave a 4 inch gap between the studs and concrete wall and probably get away with it.

Stud walls on concrete slab.

Remove the curb and clean the slab thoroughly with a wire brush. Consult your building plans and snap a chalk line to outline the area for the stud wall with pair of lines parallel and 3 1 2 inches apart. Use a tape measure to mark out the location of the remaining studs along the wall. Using a plumb bob or laser level transfer those locations to the top plates.

Then fill the holes in the slab with hydraulic cement. By doing this you will avoid having the concrete bolt end up under a stud position. Most jurisdictions require a 4 mil plastic sheet vapor barrier for basement walls against concrete. Wall studs are typically installed at 16 intervals when measured at their centers.

Trick when placing the concrete anchors either the lbolts or lag shields mark a length of 2 x 4 with the position of the studs lay it beside the concrete pad and insert the concrete bolts betweenmarks. That is if the studs are going to touch the concrete wall. Choose a length that will penetrate the concrete at least 1 inch. The gasket must be designed specifically for use with.

Run a chalk snap line between the marks and snap the line against the slab to lay out the position of one of the wall s sides. Measure mark and cut a 2 by 4 to serve as the bottom. Lay a continuous layer of 1 4 inch foam gasket or similar moisture and air barrier on top of the concrete slab before applying sill plates. Start at one end of a wall and mark the location of the first stud.

Some concrete nails are the cut nail design shown in the photo with a thick flat shank and a tapering v profile. If this is the case drill through the curb and into the slab with a roto hammer every few feet. Exterior wall on slab must be out on the edge an exterior wall must be placed on the outside edge of the slab so the exterior siding laps down and over the edge of the slab. Other nails have a thick shank that sometimes has spiral ridges for improved holding power.

Your local building code may call for the wall to be anchored to the slab with threaded rods. So there is enough gap for air to flow. Stretch a tape measure across the concrete slab and mark the position of the wall s ends.
