Post-tensioned concrete is a specialized approach within reinforced concrete design that allows structural elements—especially slabs and beams—to be pre-tensioned to resist loads. This technique enables longer spans, reduces concrete and rebar quantities, and improves overall structural efficiency and sustainability.
At McNamara • Salvia, we frequently use post-tensioning to create navigable parking garages, column-free residential and commercial spaces, and as tie-downs to resist wind and earthquake forces. It also allows us to realize ambitious architectural designs—including long spans, cantilevers, slender towers, and other innovative building forms. Beyond aesthetics, post-tensioning enhances durability and extends the lifespan of structures with demanding performance requirements or challenging environmental exposures.
