The oval structures were formed inside and sprayed and cut to shape, with massive cost savings compared to traditional form and poured concrete leaving. The architectural landmark with fascinating curved forms is a salute to the advantages of shotcrete design.

What is shotcrete?

Shotcreting is “the spraying of concrete via air or hydraulic pressure.” In the USA, where the process was invented, shotcrete is commonly called Gunite. Since its inception in the early 1900s, shotcrete application has advanced and can be achieved by two methods:

  1. Shotcrete: Using mechanics and hydraulics to force wet concrete through a hose, where compressed air increases the shotcrete’s velocity at discharge.
  2. Dry Shot or Dry Spray: Using compressed air to blow a dry mix through a hose, where water is then added at discharge.
