Quality Control

Quality control is a very important part of post tensioning works. To have a good post tensioning job we have to control the following:

  • The selection of materials
  • The accurate and precise installation of unbonded strands and tendons and as per the approved drawings by the engineer
  • The installation of bursting steel.
  • The callibration of stressing jacks.
  • The acceptable elongation of strands and as per the design requirements.
  • The tight sealing of caps.
  • To test the strength of strands and tendons according to ASTM (American Society for Test and Measurements) requirements.
