Q: Is it possible that a post-tensioned garage slab could literally buckle in half when the tendons are tensioned, or does rebar in the slab prevent that from happening? Also, why are these types of slabs so common in Las Vegas? Is it because of the soil?
Expansive soils can wreak havoc on conventional wire-mesh reinforced slabs. A California structural engineer explains why post-tensioned slabs have become a popular solution for building on problem soils.
