Märzenkeller, Austria Projects Description The old gallery system (≈ 2000 m length) had to be repaired/stabilized. Originally steel fibres were planned. But since the gallery will be partly open to the public and sticking out steel fibres can cause injuries, the designer decided to switch to the synthetic high-performance fibre Concrix ES. Advantages of Concrix…
Hydro Power Plant Station «Berschnerbach», Berschis (CH) Projects 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…

Excavation, shotcrete infill – Biology Centre University Vienna (AT) Projects Description The excavation stabilisation made with discontinuous bored pile walls with shotcrete infilling for the new Biology Centre for the University of Vienna. The originally planned reinforcement for infilling was AQ 65 steel mesh (332 mm²/m), which was totally replaced by using macro fiber reinforced…
Exploration Tunnel Feldkirch City Tunnel (AT) Projects Description The construction of the 1212-meter-long exploration tunnel Tisis, as part of the Feldkirch City Tunnel project in Austria, was initiated by the Allianz EKS Tisis Jägerbau, Strabag, State of Vorarlberg. To fulfil its safety function after excavation and also as part of the permanent inner shell, macro-fibre…
SiSto Carpeting Tunnel (CH) Projects Description The construction of the 2036 m long road safety tunnel Crapteig started 2018 and finished 2022. The use of synthetic fibre reinforced sprayed concrete for the initial protection and for the sprayed permanent inner lining allowed a progress of 24 m/week compared to the originally steel reinforced (mesh) solution…
Cable Ducts (NL) Projects Description Various sizes of prefab cable ducts produced by our partner Strukton Prefab in the Netherlands. These duct elements will be used for installing high voltage cables and they are only reinforced with synthetic macrofibres Concrix ES or Concrix HS35 depending on element thickness. Our customer appreciates our on-site service, the…
Stein (CH) Projects Description In the vicinity of Stein, Switzerland, a roundabout constructed with macrofibre-reinforced concrete stands strong after 12 years. Unlike asphalt, this resilient solution resists deformations from heavy traffic, showcasing its durability, cost-effectiveness, and eco-friendliness. The accompanying images testify to the enduring strength and economic viability, highlighting the lasting benefits of fiber-reinforced concrete…
Vlaardingen (NL) Projects Description In diverse areas of infrastructure construction like roundabouts, the use of macro-synthetic fibre-reinforced concrete is proving to be the best measure for saving costs, time and CO₂ and at the same time not having to accept any qualitative or technical disadvantages. Our powerful macrofibre Concrix ES blended with our natural microfibre…
