Headwalls

Headwalls

Adfil Macro & Micro Synthetic Fibres can be used in precast headwalls to replace conventional steel mesh.

Through the finite element design criteria, fibre-reinforced concrete was able to match the required loadings, pressures and installation values required for these units. These products are under constant attack from water and slurry passing through them. Any breach in the structure of these products would leave them susceptible to the ingress of liquid which would eventually corrode steel reinforcement and cause the concrete to fail.

Advantages

  • Reduced manufacture costs
  • Reduced Transport costs
  • Reduced reinforcement storage requirement
  • Reduced Co2 emissions
  • Better energy absorption from the external abutment pressures
