System Stressing and Grouting

Our highly trained field leadership provides expertise in all areas of post-tensioning installation services– including stressing and grouting operations.

Tendon Inspection & Vacuum Grouting

Working under ANSI guidelines, STRUCTURAL TECHNOLOGIES uses a statistical approach to random sampling during investigation. Using non-destructive Ground Penetrating Radar (GPR) and field layout drawings, we can locate existing post-tensioning tendons for inspection. The use of a borescope allows for detailed visual inspection and captured video footage can be shared with the owner and the engineer. Where voids are found, they are documented and filled using one of several grouting methods:

  • Vacuum grouting
  • Vacuum-assisted grouting
  • Pressure grouting
