We have already paid for a design, prepared contract drawings,  so how can I allow your product to compete ?

  •  contract tender documents, under Special Provisions,  state that the  "municiipality will entertain a value added alternative bridge as a potential substitute to the contract drawings shown in line item___ provided that he proponents  alternative product includes stamped drawings by a third party engineering firm for consideration  by the municipality as it reserves the right to review equivalency  in its sole opinion and subsequently accept or reject the alternative without explanation to the proponent."
  • this allows transparency, competition at the tendering stage
  • still subject to review, acceptance or rejection
  • bid bond, performance bonds, labor and material bonds included as required
  • opportunity to save time and money


Other fiberglass composite manufactures use vinyl ester or polyester resins, why do you use epoxy?


  • we do not recommend vinyl ester or polyester based resins as they are inferior to epoxy and will fail prematurely
  • epoxy reinforced with fiberglass does not micro crack under SLS or ULS 
  • epoxy is even specified by the American Concrete Institute for injecting concrete to repair reinforced concrete failing in shear, tension, compression
  • during our testing vinyl ester or polyester resins (some reinforced with epoxy backbone) will fail at the connections due to dynamic loading fatigue
  • epoxy in our opinion is the only material that meets durability standards


What about Salt and de-icing materials?

  • unlike concrete our products are epoxy reinforece and immune to water ingress, salt and de-icing materials
  • the chemistry of our epoxy is not attacked by salt, de-icing materials


What about U.V.?

  • our epoxy resin system has been accelerated tested UV A&B Chamber and there was approx. one micron of loss which means excellent resistance
  • we do not recommend vinyl ester or polyester resins even if fortified with epoxy because they will fade


What about water ingress?

  • concrete absorbs water, our epoxy resin does not and is immune to water ingress
  • we do not recommend polyesters or vinyl esters products for bridge applications
  • our resin is a proprietary epoxy resin formulation that has been tested hydrostatically


Why can I trust fiberglass composite bridges?

  • Fiberglass has a long history since 1950's
  • Fiberglass composites have replaced concrete and steel in very demanding applications such as Pulp Paper, Chemical Treatment, Gasoline,
  • Advanced fiberglass is used in Aerospace, Commercial Airplanes, Ballistic, Implosion, Explosion applications
  • The first use of fiberglass for bridges is for earthquake or siesmic zones
  • The American Concrete institute has many documents and specifications for rehabilitating concrete with FRP
  • The Canadian Highway Bridge Design Code has Section 16 for Fiberglass
  • Concrete is poor in tension and engineers internally reinforce with rebar so Fiberglass also requires engineers who are skilled in the art and there are a growing number of civil engineers who have increased their skill sets


Why do you use wood?

  • Ministry of Transportation Ontario has written many reports validating it for highway bridges
  • wood is a structural element
  • wood is a one way plate, having about the same strength of concrete in the direction of the fibers
  • wood is poor in the radial direction of fiber and for this reason it is not a two way plate
  • the problem is that universities don't have a sufficient wood program compared to steel and concrete
  • concrete is poor in tension, so engineers internally reinforce concrete with rebar to make it a 2 way plate 
  • fiberglass composite is a two way plate and more competitive being 1/5th weight of concrete and 800MPa
  • wood without fiberglass requires twice as many steel girders as it only transfers loads to the steel girders
  • wood is extremely beneficial for frequency to be redundant
  • wood is a structural material, but also renewable, sustainable
  • fiberglass composite structures when they reach the end of their life can also be recylced


 Why would i choose fiberglass composite over steel?

  • pound for pound wood is stronger than steel,
  • steel beams, HSS elements are not manufactured in Canada & using wood promotes livelihood in Canada
  • steel beams require a coating system that usually lasts about 25 years and the cost of repainting on site is prohibiltive due to environmental issues
  • steel is one of the worst offenders for sustainability producing C02 Emissions
  • steel yields around 3% whereas fiberglass composite yields 9% and can be made to fail ductile
  • steel requires more engineering for torsion than fiberglass composite 
  • fiberglass is excellent in fatigue as long as the strain is below 30% at ULS and we are .005%  



Are you claiming that fiberglass composite is superior to concrete and steel?

Title:   ISIS Technologies for 21st Century Bridge Structures

Aftab A. Mufti

President, ISIS Canada, University of Manitoba

Winnipeg, MB



Modern and innovative technologies, developed as part of ISIS Canada activities, involve new building materials comprised of polymers and super-strong fibres, and innovative sensors incorporating fiber optics.



Innovative Structures, Bridge Decks, Columns, Beams, Barrier Walls



Canada’s infrastructure assets have an estimated value of $2 trillion. The cost of rehabilitating this deteriorating asset is an estimated $49 billion. It is implicitly understood that an effective rehabilitation program should not and must not be carried out using old technology.

ISIS Canada, A Network of Centre of Excellence is in a position to make substantial contribution toward this goal. This research organization intends to expend its resources over the nest seven years 2002-2009, advancing the widespread use of new technologies in infrastructure projects mainly by judicious and innovative use of fibre reinforced polymers (FRP’s) and fibre optic sensing (FOS) devices.


  • After 4 years of Research & Development Tesitng they concluded that fiberglass must be used if bridge owners are to make there bridges last longer considering the backlog of deficient, obsolete bridges


  • In the year 2000 The Canadian Highway Bridge Design Code published Section 16 incorporating fiberglass


  • We believe that conditional loads, not service loads cause concrete, steel to prematurely fail before the 75 year design life is realized, in fact most concrete bridges require rehabilitation within 25-30 years


  • Conditional loads being water ingress, one of the strongest solvents in the world, penetrates concrete causing de-icing materials, salt to saturate the concrete with chloride content


  • The solution is to keep the water, de-icing materials out which is why encapsulating wood with epoxy fiberglass laminate works in durability and capacity as a hybrid solution
