About Fyfe Tyfo® Fibrwrap®

Since 1988, The Tyfo® Fibrwrap® Systems have been tested and proven for effectiveness and durability. Over 500 structural and material tests, both destructive and non-destructive, have been performed on the Tyfo® Fibrwrap® Systems. These include full-scale structural testing for a variety of design goals, long-term environmental durability testing, and in-situ testing of actual installations. The result is reliable composite strengthening systems that have demonstrated intended design performances.

The Fyfe Group is comprised of engineers, designers, material specialists, material manufacturers and project support personnel. Working together, this team provides innovative construction products and technical support to meet the needs of engineers, contractors and owners.


Tyfo® Fibrwrap® FRP Composite Strengthening

5 Step Process to Deliver a Successful Project

Step 1:


Working together as a team, Fyfe engineers are able to provide you with a preliminary design at no cost.
Step 2:

Product Properties

An extensive range of certified products are available to choose from. This helps to optimise your project’s requirements.
Step 3:

Testing and Certification

When providing structural retrofit, you need a dependable solution. Tyfo® Fribrwrap®system complies to the ICC-Evaluation Service under sections ICC AC 125 and 178, as well as CodeMarkproviding proof that our FRP system fulfils the relevant clauses of the New Zealand Building Code (NZBC).
Step 4:


Having products you can depend on provides peace of mind. Having a pre-qualified and annually audited application company ensures that the application is carried out correctly. Concrete Solutions®is annually audited and can boast over 200 Tyfo® project
Step 5:


Collectively bring together the criteria of Steps 1, 2, 3 and 4 to provide quality assurance.

CodeMark Certified Product

Tyfo® Fibrwrap® Systems are CodeMark certified which means Tyfo® conforms to relevant standards of the New Zealand Building Code. CodeMark also includes a wide range of strict quality controls to ensure certified Tyfo® FRP systems will meet durability requirements of a minimum of 50 years as stipulated in the New Zealand Building Code, giving engineers the confidence to specify them.

CodeMark provides the building owner or specifier confidence that the system is compliant with the New Zealand Building Code; has been tested by an independent evaluation service for its manufacture, design, installation, inspection and durability having an annual audit.

Tyfo® a lightweight tension member for columns, beams, walls and slabs

Seismic Retrofit

The Tyfo® Fibrwrap® System is an ideal method to improve the seismic performance of buildings including URM structures. The high strength to weight ratio of composite materials allow for significant increase in performance, while adding minimal dead weight to the structure. Additional shear capacity, flexural capacity and rotational capacity can be added to columns, beams, slabs and walls. The Tyfo® Fibrwrap® System can also be designed to act as a drag strut or provide member-to-member shear transfer.


  • In-plane shear strength
  • In-plane flexural strength
  • Out-of-Plane flexural strength
  • Shear transfer between wall panels
  • Ductility
  • Axial strength

Uses may vary depending on application area, check ICC documentation for tested areas.

Structural Upgrades

The Tyfo® Fibrwrap® System can be used to improve the load carrying capacity and structural performance of both reinforced concrete and masonry walls of a building. Additional shear and flexural capacity can be added to beams, columns, slabs and walls. The system has been used extensively for civil infrastructure such as bridges, tunnels and elevated roadways worldwide. It allows for increased load ratings, rehabilitation of corroded or desressted members, extension of service life and even construction error remediation.

The Tyfo® AFP System can be used to provide UL tested hourly fire ratings when required.

Tyfo® Fibrwrap® Anchoring Systems

Tyfo® Anchor

The fibre anchor concept was invented ( US Patent #7,574,840 B1) and developed by Fyfe Co. LLC in order to improve the performance of various Tyfo® Fibrwrap® System designs. The low profile, non-corrosive fibre anchor is manufactured using the Tyfo® SCH (primary carbon) and SEH (primary glass) fibres combined with the Tyfo® S epoxy.

Testing has been conducted by The University of Canterbury New Zealand, The University of Texas at Austin, The University of California at San Diego, The US Army Corps of Engineers, The University of Washington, Washington State University, The University of Patras, Ain Sham University in Cairo and The University of Toronto. Our research continues at these and other universities in order to improve and refine these designs and details.


  • Develop tension forces though obstacles
  • Develop tension and shear forces by embedment
  • Improve structural performance of beam and wall shear designs
  • Improve structural performance of beam and slab flexural designs
  • Prevent pull-out and/or de-bonding at ultimate loads

Tyfo® Rehabilitation of Existing Structures

Alkali-silica Reaction (ASR)

Concrete Solutions® has successfully rehabilitated structures containing ASR such as bridges by applying Tyfo® wet-lay fabrics for providing confinement and preventing water from entering into the concrete.

Structural concrete repairs have incorporated the use of Tyfo® products due to their unique properties of being light weight, non-corrosive, applied to the structures exterior and are relatively easy to apply. These properties enable an array of rehabilitation applications including; additional reinforcement to badly spalled concrete, ASR confinement and preventing chemical attack. Rehabilitation is not just limited to concrete structures but has also included steel and timber structures such as bridges and wharf piles.

Tyfo® PR Jackets and underwater applications

  • Thoroughly tested at independent laboratories
  • Can prevent the onset of corrosion when applied to new structural elements
  • Can be installed below the water line
  • Excellent long-term material properties in water
  • Can be used on circular, square, rectangular, hexagonal, flared and alternative shaped cross sections
  • Cost-effective
