Structural Repair and Strengthening

External Post Tensioning to Restore or Increase Capacity

Structures often require strengthening due to deterioration, overloading, construction defects, or simply change of purpose. DSI provides the engineered systems and field technicians to improve both concrete or steel structures. The pictures to the right show a football stadium walkway and seating support structure being strengthened with external Double Corrosion Protection (DCP) THREADBAR^® tendons. Also shown (lower right) are epoxy coated strands being utilized to strengthen a steel girder bridge.
