Hi all, first let me say I'm really ignorant about this stuff...
Looking at two homes in Florida, one is a slab foundation and the other continuous footing.
Anyone know which is preferable (Florida gulf coast)? Here in NC I have a crawlspace.
Thanks!
The slab home also has a (theoretical) footing so I’m wondering if it’s just the terminology that’s confusing you?
Some slab homes have what’s called a monolithic footing that’s sometimes referred to as a “haunched slab”. You can look at and view photos/details of both types of construction, however each one is designed contingent upon the soil conditions and frost depth depending of the specific geographical area.
In your case in Florida, I don’t think there’s an advantage to one type over the other.
First photo is a haunched slab or grade beam foundation while the one on the right is a more typical footing/wall foundation.
Thank you! Yeah I think it was the terminology. One of the homes has this on the tax assessor/property listing:
Building Type: Single Family
Quality: Average
Foundation: Continuous Footing
Floor System: Slab On Grade
Exterior Wall: Concrete Block
Roof Frame: Gable Or Hip
Roof Cover: Shingle Composition
EDIT: I just answered my own question...slab on grade is the terrazzo floor (oops)
Been going to the gulf coast for more than 30yrs- at least once a yr. And I always snoop around at any new construction that going on.
Mono-slabs are not that common there; but the “continuous footing” style slab is. It’s a labor cost/soil condition factor. Mono-slab. as the name implies, is a footing and slab done in one process. The “continuous footing” style is a conventional footing, block stem wall, and a placed slab.
Now you have a complete explanation to your self-answered question.
My last home in SC (2400sq ft, one story) had a raised slab. Concrete foundations were raised about 2 ft. with the cavity filled with some type of sand (was a special type sand and I forget the name) then the slab was poured on top of the sand. There was also a brick facia around the outer edges of the foundation.

Yes, they would use “dead sand” or “concrete sand” which is quarry processed and the advantage is that it’s doesn’t compact or settle so it’s great for backfilling under certain conditions.
