Tunnelling Reinforcement
Fibreglass reinforced solutions (GFRP), a well-established method for consolidation and reinforcement of the excavation face in underground construction, enhance soil stability and improve safety conditions. Our portfolio features a wide range of innovative solutions:
- Profiles and elements in fibreglass of different section
- The customizable anchoring systems P.E.R. Ground
- Glass fibre reinforcement nets
- Glass fibre reinforcing bars
Corrugated Fibreglass Hollow Sections
The corrugated fibreglass hollow sections, made from a polyester resin matrix reinforced with continuous unidirectional E-Glass type GFRP fibres, maintain the integrity of the fibres throughout their length. This uninterrupted fibreglass reinforcement significantly enhances tensile strength and pull-out resistance. The corrugated design also increases adhesion, and when combined with the high tensile capacity of the tube, ensures reliable stabilization of the excavation face.
