Post Tension Stress Cables, are a major support for the concrete slab construction. Before the concrete is pored the stress cables are fused at one end and laid in a wavey motion. 24 hrs after the poring process the cables are pulled by the onions at one end. This process is repeated a week later to asses the strength of the concrete. The pulling tension straightens the waves in the cable, to help hold up the concrete slab construction. On the image to the left we can see by the pink marks how much the cable has been pulled by.
