STRUCTURAL TECHNOLOGIES offers the most strengthening solutions available under one roof. Our custom-designed products add or restore load-carrying capacity for the most complex infrastructure challenges. Our products are fully integrated with our extensive engineering support services. This powerful combination translates into highly engineered solutions for our customers—which include owners, builders, managers, and designers of non-residential infrastructure.
STRUCTURAL TECHNOLOGIES’ proprietary products are used to increase the load-carrying capacity of reinforced concrete and other structure types, including masonry, timber and steel. These systems may be used alone, or in any combination - including other commercially available products to solve complex structural load requirement changes.
STRUCTURAL TECHNOLOGIES’ V-Wrap™ externally bonded FRP Systems utilize lightweight, high-strength carbon fibers bonded with adhesive resins. Our systems are used to increase or restore load-carrying capacity to a variety of structures. Low profile and flexible, FRP is ideal for applications with limited access, and/or complex geometries.
V-Wrap™ FRP Composite System Features:
- High tensile strength
- Corrosion resistant
- Installs quickly with no heavy equipment required
- Maintains shape and aesthetics of the structure
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:
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.
- Very high flexural, shear, and compressive strengths
- Extremely high energy absorption characteristics
- Ductility characteristics similar to steel
STRUCTURAL TECHNOLOGIES’ external post-tensioning systems utilize high strength prestressing cables, strands and steel bars, and are used to increase or restore load-carrying capacity to a variety of structures. Our engineers help design these versatile systems to reduce tensile stresses, cracking and deflection. By creating uplift or offset deflections, significant load capacity increases can be achieved while also minimizing and controlling crack formation.
External P-T System Features:
- Improves stress conditions
- Effective against crack formation
- Controls deflection
- Improves the strength of the structural elements
Structural Technologies, LLC and VStructural, LLC are Structural Group, Inc. Companies. VStructural, LLC is the exclusive licensee of VSL® Post-Tensioning Systems in the United States.

STRUCTURAL TECHNOLOGIES’ Tstrata™ 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, enlargement and overlay systems are ideal for situations that require improved strength and stiffness.
Tstrata™ Enlargement System Features:
- Pressurized forming systems for enhanced bond that ensures that the structure and enlargement acts as a single composite in order to achieve design strength capacity
- Different strengthening levels achieved by changing amount/layout of additional steel
- Improves the stiffness of the structural elements
- Controls deflection
- Produces fire proofed solution
