Supporting interior walls on ground level
Supporting interior walls on ground level
(OP)
Hello all,
What is typical practice when it comes to supporting an interior load bearing wall...does it sit directly on top of the grade beam with a slab on grade stopping at each face of the grade beam or does the slab run over the grade beam and the wall sits on the S.O.G? Does it differ at door locations?
Thank you!

quicker
less ingress of moisture
it is also stiffer.
That said, the amound and type of insulation under the slab sometimes dictates the detail.

Few concrete finishers are able to get slabs perfectly flat or even close.
If one is building a load bearing wall that is "up and down" with the variations in the floor and the framing contractor doesn't cut every stud to ensure the top of the wall is flat, the the problem can propagate right through the structure.
If the concrete contractor takes the proper steps to ensure a nice flat pour, then a thickened slab is probably the way to go.
For my money, however, I go with the block as the masons will string the course in order to make sure the course is perfectly level and straight. As I mention before, if in a garage type area that may be getting wet/moisture, it is nice to have wood or metal framing up off the floor a few inches also.
I won't deny that the thickened slab is the cheaper alternative.

Usually the framing contractor is the second guy on the job and having the slab pour often means that the plumbers and sometimes electricians will have to have all their installations in place prior to the framer starting. This can lead to mistakes if the plumbers and electricians don't have a good set of plans.

Yes, slab flatness is a construction issue for the framer. Be tough and make the finishers do it right.
