Concrete-Free Slab Assembly: The Cons
We have been discussing the possibility of using a concrete free slab with our architect and builder. It seems like a great way to reduce our carbon footprint and probably give us a more forgiving surface to stand on.
However, they have some trepidation about it. I respect that there can be very good reasons not to do this kind of assembly, but I’m trying to understand what those might be.
For reference, this would be in an urban infill lot in Climate Zone 5. The soil conditions are a bit of a wildcard. There was a house on the lot for about 60 years, but it had a fire, was condemned, and was eventually buried on the lot. Gentle slope down from back to front of the lot.
Are there obvious conditions or scenarios where going with a concrete free slab assembly becomes a bad idea or too much of an engineering challenge to be worth it, practically speaking? What kinds of conditions would those be?
