Floor system on Slab foundation
Hello everyone, quick back story. I’m building a home at a estates that’s close to a riverbank. So because of potential unstable soil you need a Engineered Raft Foundation. And to cut back on overhead costs we decided to go with a Engineered raft Slab Foundation instead of a dug basement, and then we started looking at Radiant heat to put right in the slab which ended up being to expensive.
So here is my question, we need to go with forced air and we have a Slab foundation. At the current moment we are thinking of putting a open web engineered floor truss on top of the slab so we can run ducting. Is there any other options we could do that would be more cost effective.
PS. Many might suggest a crawl space but we have already had the slab engineered
