RE: SOG foundations

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I should clarify, I was talking about exterior slabs – sorry. I thought this was in reference to Gail’s Wyoming deck project for some reason.

 

For a wood framed residence, yes, 6” separation to the mudsill. But that is done several different ways. Many times the top of slab is very close to flush with the exterior fin. Grade but a curb is built at the edges to lift the mudsill 6” above grade.

 

In the field, I usually see about 2”-6” of separation at the mudsill.

 

Site plans generally show to pad elevation and top of slab elevation. Grading plans should show the finish grade elevations at key points around the house perimeter.

a) I always call it out as 6”.  There is a blurb in the code (2304.11.2.2) that mentions this in regards to pressure treatment of sheathing and sill plates.

b) 2” – 4” from what I’ve seen is common.  I’ve never seen 0” on new construction, only after it’s been lived in and landscaped.

Typically on plans it isn’t shown, but when I have seen it, it’s about 2” to 3”.

 

In the field, it’s usually flush or zero.

When designing residential slab-on-ground foundations,  what is the typical distance between the top of slab elevation and the finished grade elevation:

 

a.  As typically shown on the plans

b.  As typically actually built
