<p>This Architectural Drawing is AutoCAD 2d drawing of Post tension slab details in AutoCAD, dwg file. Post-tension concrete slabs are used <strong>to create a monolithic (single pour) slab that is stronger than a traditional slab without reinforcement</strong>. This is achieved by laying out high-strength steel cables in a crisscrossed grid pattern throughout the foundation prior to pouring the concrete.</p>
