Double T Anchor
Non-corrosive, easy to install anchor for stabilization of parking garage flange movement.
Fortec Stabilization has performed full scale testing of the new Fortec Double Tee Anchor to repair an active parking garage with typical flange failures. The parking deck’s Double-T beams are 60-feet long, 8-feet wide with a 4 inch, non-topped deck. The Fortec Double Tee Anchor is formed using carbon fiber in a U-shaped polymer composite, precured and surface prepped for installation.
As owners and operators of parking structures know well, standard steel welded flange connections typically fail. Load forces cause premature failure of welded flange connectors either in the connector or more commonly in the concrete flange surrounding the connector. The welded connection is too rigid and causes fatigue failure in the weld or cracking of the concrete surrounding the connector’s embedded anchors.
Current composite and steel repair methods also create a rigid joint having similar failures to the original connectors. Without allowing for a nominal amount of movement or flex, the connection is prone to failure. The lack of ductility in these repairs repeats fatigue failure in the concrete or the connector. Fortec Double Tee Anchors significantly reduce movement of the concrete beams while allowing for a small amount of flex in the joint creating a load transfer system through the carbon fiber and arrest fatigue stress in the concrete and the connector.
Fortec 5680-BD Kevlar®
Kevlar® aramid fiber fabric for crack repair, segmental seam repair, waterproofing and structural reinforcement.
Fortec 5680-BD Kevlar® is an aramid fiber fabric system comprised of highly durable 5,680 denier Kevlar® yarns, producing a superior and dense weave. The system is designed for heavy duty crack repair, crack control, and structural strengthening of concrete and masonry structures where durability, impact resistance and protection of water intrusion is needed. The system of Fortec 5680-BD Kevlar® textile used with Fortec Lo-Mod 526 Flexible epoxy resin is the best alliance of strength and bonding that seals out moisture, transfers loads and allows temperature and stress related movements to occur without brittleness.
- 0o and 90o, equal bi-directional strength
- High bond strength
- Conforms to irregular surfaces
- Easy gun-applied epoxy resins
- Strongest duty Kevlar system available
- Excellent crack control

Fortec Carbon Tow Sheet
Unidirectional Carbon Fiber Textile or Tow Sheet for structural reinforcement and containment. Available in 150, 300, 600 and 700 GSM
Fortec Carbon Tow Sheet is a flexible, woven, unidirectional carbon fiber textile with a lightweight scrim on both sides designed for use as an externally applied reinforcement for strengthening concrete, timber and masonry structures. Fortec Carbon Tow Sheets are typically field installed using either Fortec #4550 LPL or #1276 LPL Hi-Modulus Fiber Matrix epoxy resins to form an inexpensive carbon fiber reinforced polymer (CFRP) system.
- Reinforcement & strengthening of irregular shapes
- Column wrapping
- Cantilever retaining wall reinforcing
- Supplementary reinforcing of beams & slabs
- Inert reinforcement in highly corrosive environments
Corner Strap Fiber Reinforced Polymer
The pre-preg, pre-cured corner straps are designed based on steel plating systems.
They follow ACI design guideline in being slightly less than 90 degrees. (The function of bend amount is to carry load around corner.) This has the advantage over wet lay up systems in that the bend is certified in factory. The corner product represents a low profile bearing tendon to distribute load horizontally.

The corner product represents a low profile bearing tendon to distribute load horizontally. Corners can be produced in various plates or solid carbon,glass aramid or grids.Tensile strength and modulus are a function of tow size and layers.
Key Features and Advantages
- Low profile and can be installed behind brick facade or other building facades.
- Legs or overlaps can be added to extend loads
- Parge coats and painting can be used for aesthetics
- Installs in same fashion as straight carbon plate or grids
- Reduces or illuminates contractor error in bending FRP to far to carry load
- Peel-ply technology on both sides for increased bonding capabilities

- Moisture Insensitive & low temperature cure
- #4550 LPL Fiber Matrix Structural Epoxy
The Grid Stitch is the premier Crack Repair product on the market. Tested at over 6700lbs of tensile strength, the Grid Stitch is ideal for applications including walls, columns, bridges, parking structures, and any other surface with lateral expansion cracking.
The Grid Stitch installs in minutes with a single saw cut per stitch and application of the epoxy.
- 15 Stitches in kit
- 4000 Structural Epoxy wit Mixer
- Purdy knife and gloves
This is a new type of anchorage system, called “staple” anchor as a means of anchoring externally bonded fiber-reinforced polymers (FcRP) sheets into concrete. The staple anchors are designed in two different types: flat and round staples. Both the types of anchors are provided as prefabricated elements formed by strands of carbon fibers that are inserting into epoxy filled holes in the concrete, and an external part that is also impregnated and connected eternally to the bonded FRP laminate. They appear in different shapes and sizes and they also have different processes of installation, but they share the same aim: enhance the bond of externally bonded FRP laminates into concrete.
The staple system was rigorously tested at the University of Miami in a variety of configurations and conditions.
