How long after installation is the stressing done?

Our PTI certified technicians will be on site to stress the tendons when the concrete strength is at 1500 psi or 7-10 days after the concrete was poured.  All of our tendons are marked, tensioned using calibrated stressing pumps and rams, and the tendon elongations are verified to be in accordance with the design requirement prior to being cut and patched.
