Foundation Walls

[gregb]

If there is a concrete slab foundation, ergo, there must be foundation walls.

Sorry App601. I was replying to Tom. I just check slab and concrete.

Can you show me where is the foundation wall in this example of a typical concrete slab construction?

Damn right. But the slab itself is not a foundation. The footer and stem walls are the foundation.

The weight bearing portions, mostly perimiter. The example is a monolithic slab, but it still has a foundation wall. Its just not very high because of no frost line.

Damn right.

Please go to the above link and show me the foundation wall

That is not a wall It is the footer that is part of the concrete slab

These are foundation walls

Please also read this about Slab on Grade Construction which is typical in PR

http://www.ecohome.net/guide/slab-grade-technical-guide

And this was extracted from this page

Slab-on-grade construction is a somewhat uncommon method of home building that replaces the conventional foundation wall and basement with a concrete slab that rests directly on grade. The technique lends itself to most types of terrain, with the exception of heavily sloped sites.

To summarize I will continue to write None or N/A for foundation walls unless I find a house with a basement which in fact I did one several years ago and I wrote RC

I think there is a massive amount of hair splitting going on in this thread. Slab on grade is "unconventional"? I agree, and it would not meet Southern Building code, or any other. That's why they have footers and stem walls made of reinforced concrete to support weight bearing walls.

Tom This is typical in Puerto Rico The slab in on grade but the footers are below
That is why I write 'none" in Foundation walls and explain in additional comments what are foundation walls
However it appears nobody agrees with me

Best regards
