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.
