Proprietary Products

High-performance products and systems, in-house applications engineering specialists, and the ability to evaluate multiple options ensures the optimum solution rather than a one-size-fits-all approach.

DUCON® Micro-Reinforced Concrete Systems

DUCON

DUCON® is an innovative, high-performance system designed for extreme load resistance and energy absorption. DUCON® combines an infuseable ultra-high-performance grout with a densely layered MicroMat® steel reinforcement system.

Placement characteristics similar to concrete, combined with the ductility and energy absorption properties of steel, give DUCON® “moldable, steel-like” characteristics.

DUCON® System Features:
  • Very high flexural, shear, and compressive strengths
  • Extremely high energy absorption characteristics
  • Ductility characteristics similar to steel

DUCON® and MicroMat® trade names and patents are owned by DUCON GmbH and are distributed exclusively in North America by STRUCTURAL TECHNOLOGIES for strengthening and force protection applications.

V-Wrap Carbon & Glass FRP Composite Systems

V-WrapSTRUCTURAL TECHNOLOGIES’ externally bonded FRP systems utilize lightweight, high-strength carbon fibers bonded with adhesive resins. V-Wrap™ systems are typically used in force protection applications for standoff threats.

V-Wrap™ is extremely flexible in its application and can be used on nearly any type of structural member in order to harden, increase structural capacity and help protect against uplift, progressive collapse and spalling.

V-Wrap FRP Composite System Features:
  • 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

Tstrata Enlargement Systems

Tstrata Enlargement SysytemsSTRUCTURAL TECHNOLOGIES’ enlargement systems bond additional reinforced concrete to existing structures. Our systems are used to increase or restore load-carrying capacity to a variety of structures. Customized for every application, these systems are ideal for situations that require improved strength and stiffness.

VSL® Bonded, Post Tensioned Floor Systems

Bonded P-TAs part of its full line of Force Protection solutions, STRUCTURAL TECHNOLOGIES brings to its clients bonded post-tensioning (P-T) technology that can be used to meet force protection and progressive collapse requirements in new construction.

STRUCTURAL TECHNOLOGIES can provide feasibility analysis, design assistance and cost development for a full range of P-T products and solutions to enhance force protection capabilities of existing structures as well as new construction applications.

READ MORE
 
Enhancing new construction designs against progressive collapse:
  • Pre-stress force is ideally located for bending due to gravity loads and blast loads
  • Use of high strength strands improve a members ability to withstand a higher blast loadBonded PT can maintain continuity and prestress force if an anchorage is lost
  • For beams and slabs, bonded tendons can be profiled to counter the internal forces resulting from a lost column and to resist moment reversals that can occur during a blast event

Structural Technologies, LLC is the exclusive licensee of VSL® Post-Tensioning Systems in the United States.
