For special requirements in the strengthening of structures made of steel and reinforced concrete, S&P has developed a special procedure to pre-stress FRP laminates and rods with up to 140 kN. The procedure requires appropriate planning, preparation and execution and is therefore exclusively applied with the support of S&P application experts. 

The pre-stressing system has proven itself worldwide and is suitable for a wide range of applications:

• Post-strengthening of overloaded structural elements
• External pre-stressing of structures with corroded internal pre-stressed cables
• Rehabilitation of coupling joints
• Limiting flexure and deflection
• Reduction of crack widths
• Relief of joints
