What is a Post Tensioned Slab:

Post Tensioned slabs is the most commonly used solution for slabs all around Australia, especially for big developments, it is considered as the first option since it offers many benefits from bigger spans to less concrete and faster construction speed. It involves placing empty ducts and pushing strands inside these ducts which will be later stressed once the concrete has reached enough strength.
