Tunnelling breakthrough made easy with FRP rebar

Retrofit structural solutions based on CFRP
ASTEC Carbon Solutions is a range of 3 products based on the same innovative composite material: Carbon Fiber Reinforced Polymer. ASTEC CFRP offer amazing properties: 4 times the tensile performance of steel for only 1/4 of the weight.
In the past 20 years have emerged new structural applications for Carbon fiber based elements:

  • External Bonding Reinforcement (EBR), where a carbon laminate is applied on the surface to increase the flexural and shear strength of the member.
  • NSM (Near Surface Mount) applications, where a carbon rod or tape is inserted in a cut groove with cement grouting or epoxy adhesive. NSM offers a gain of 4.8x the flexural strength compared to EBR technique.
  • External post-tensioning applications, where a carbon rod is installed below a concrete member thanks to state-of-the-art splicing system.
