News & Infos Shotcrete
Shotcrete is indispensable in underground construction. It can be applied flexibly even under most adverse conditions.
News & Infos Creep and initial strength
Thanks to short initial setting time, considerable ground pressures can be taken up within hours, whilst, due to its high creep capacity, overstressing of shotcrete is avoided to a large extent.

Shotcrete model
IGT applies sophisticated constitutive models for shotcrete behaviour in underground conditions which account for:

  • strength development over time
  • cracking under tension
  • bursting under excessive compression
  • increasing deformation under constant load (creep)
  • decreasing stresses under constant strain (relaxation)
The robust implementation of the shotcrete model allows its everyday application.
