Post-tension slab foundations use high-strength steel cables to keep concrete in constant compression — dramatically reducing the risk of cracks.
In this video, you'll see how these systems are built, how they differ from traditional rebar-reinforced slabs, and why post-tensioning provides greater durability, especially in expansive or shifting soils.
Topics covered:
• Why concrete cracks under tension
• How rebar compares to post-tensioning
• What 6,500 pounds of cable tension does to a slab
• The C-clamp analogy explained
Whether you're a homeowner, builder, or home inspector, understanding the principles behind post-tensioned slabs can help you spot quality construction and prevent costly repairs.
