Description

The tunnel for the pressure water pipe of the hydro power plant station «Berschnerbach» (≈ 1300 m length) with a gradient from 20% (pipe gallery) up to 142% for the inclined shaft. The permanent inner lining sprayed concrete is only reinforced with the synthetic high-performance fibre Concrix ES.

Advantages of Concrix ES Solution:

  • Cost savings (no steel mounting, lower logistic costs, shorter construction time)
  • High performance (700 Joule after only 7 days – EN 14488-5)
  • No corrosion and thus lower future maintenance cost
  • Non-creeping-tested  and durability tested fibre
