Post-Tension
Post-Tension (or Post-Tensioning) is a construction technique used to strengthen concrete structures like building foundations, parking garages, and bridges. Think of it like adding a strong rubber band inside concrete that gets tightened after the concrete hardens, making the whole structure stronger and more durable. This method allows builders to create longer spans with less material, saving both money and space. It's different from traditional reinforced concrete because the strengthening happens after (post) the concrete is poured, rather than just putting steel bars in before the pour.
