I want to build a new home in the Orlando area. Some builders use a concrete slab. Others use something called stem wall. Which method is best, and why?

Thanks!

I am not sure what they mean by "stem wall". Stem walls are part of a concrete foundation and the structural wall rests on top of these short concrete extensions of the footings.

Are they talking about raised wood frame floor as opposed to concrete slab-on-grade?

In my experience, the raised floor may be more expensive to build, but if done properly will make living in the house more comfortable by separating the living area from the ground. That is, if you don't mind some flexibility and creaking in the floor...

Concrete, if done properly, is stronger and resists fire and termites.

One advantage of raised floor is allowing plumbing and wiring under the house in accessible area. That really helps for any repairs or remodeling.

Does that help? Let me know if stem wall means something else in Florida.

Thank you!  R.

Here's what the builder's rep told me about stem wall, but I would appreciate an unbiased interpretation. I don't get the sense that there is a raised floor.

Thanks!

A stem wall is a three step process, (footing- stem wall- concrete pour) whereby a monolithic slab is a one time concrete pour within batter boards.

A stem wall is more expensive and more time consuming. We prefer the stem wall foundation because of its strength and quality. If you get the foundation right, the rest of the house will come out much better. Monolithic is a cost saver, however it does meet all codes and is widely accepted. It's like the different between a Chevy and a Cadillac.  Both drive about the same, but the Cadillac just feels better.
