Fiberglass rebar applications in diaphragm walls (soft eye) and foundation pit retaining piles.

Tunnel Boring Machines (TBM) are widely used in tunnel projects, but TBMs are not well suited to work their way through Steel reinforced concrete structures, because of the resilience of the Steel. Steel ductility will seriously hinder the work of the rotary cutters by absorbing the cutter’s energy.


  • GFRP reinforced concrete launch box is a better option
  • Cuttability
  • Permanent application
  • 1/4 the Weight vs. Steel Rebar
  • Long-term durability
  • High end loading
  • Flexibility
  • Non-Corrosive and Unsusceptible to Chemical spills
