V-Wrap™ – Protection From Standoff Threats

A Fiber Reinforced Polymer (FRP) Reinforcing System, V-Wrap™ combines lightweight, high-strength fibers (glass or carbon) with premium resins to create an externally bonded reinforcing system that is ideal for application to existing structural elements.

Versatility and Ease of Installation

Force Protection UpliftV-Wrap™ is extremely flexible in its application and can be used on nearly any type of structural member in order to harden and increase structural capacity and protect against uplift, progressive collapse, and spalling. Because of its ability to harden a structural member without significantly increasing its size, V-Wrap™ can be used in confined space applications and on irregular member geometries. V-Wrap™ can also be used in conjunction with other systems such as DUCON®, Tstrata™ Steel Plate, and Tstrata™ Member Enlargement  to optimize a solution and increase cost efficiency.

Major Advantages of V-Wrap™ Include:
  • Increased flexural capacity of column, beam, and slabs in nearly any orientation
  • Ability to maintain column integrity through improved confinement
  • Spall protection for standoff blast applications
  • Ability to harden a structural member without significantly increasing its size
  • Speed of installation
  • Easy integration with other systems

 
Force Protection Applications

V-Wrap™ provides force protection at standoff distances for:

  • Progressive collapse caused by column failure and/or slab uplift
  • Spalling
