Tstrata Enlargement Force Protection

Force Protection with Tstrata Enlargement Systems™

Tstrata Enlargement Systems™ consist of specialty designed reinforcement systems combined with high-flow Tstrata concrete to produce an additional reinforced concrete layer that is fully bonded to existing structural members. Our systems combine specific surface preparation, specialized materials, and pressurized formwork to produce monolithic concrete enlargements.

Force Protection Applications

Section enlargement and bonded overlays can be utilized to improve blast and progressive collapse resistance of a structure by:

  • Increasing flexural and shear capacity of columns, beams, and slabs
  • Increasing axial capacity of columns
  • Increasing stiffness or deflection reduction at service levels (slabs or columns)
  • Increasing strength/mass that improves a structural member’s ability to resist failure caused by blast
  • Increasing resistance to slab uplift
  • Preventing progressive collapse caused by column failure and/or slab uplift

Advantages

  • Easy integration with existing structure
  • Uniform appearance and repair schemes that blend well with the existing structure
  • High benefit-to-cost ratio (durable and cost effective strengthening solution)
  • Inherent fire-resistance capability
  • Can be used with other force protection solutions, such as DUCON®, V-Wrap™ FRP, and Tstrata Steel Plate™

Pressure sensors inside the Tstrata Pressurized Form Technology™ show high pressure is maintained after concrete placement to ensure superior bond to existing substrate and to minimize shrinkage.

Design Elements

Tstrata Specialty Concrete Mixes™

Tstrata Specialty Concrete Mixes™
Our designs utilize Tstrata Specialty Concrete Mixes™ to allow for improved consolidation in thin enlargements and congested reinforcement zones, as well as improved bond with the existing structure.

Pressurized Forms

Pressurized Forms
Our advanced form technology creates pressure to force the new concrete into the prepared surface, creating a monolithic interface between the existing substrate and the enlargement.

Steel Reinforcement

Steel Reinforcement
Our designs are reinforced with mild steel or post-tensioning to produce the required strength and improve serviceability performance.
