In order to reduce the construction time of tunnels and make segment installation easier, FIP INDUSTRIALE has designed a mechanical system for the longitudinal connection of rings (Biblock system). Site experience has shown that the use of this system can reduce the time of ring installation up to 10%. Biblock system is manufactured with special high-resistance, unbreakable and dielectric plastic materials. Each set consists of the following elements: two sockets to be cast in the segments concrete; one connecting pin to be inserted in the sockets during installation of the segment; one bushing - optional in some models - that accompanies the pin and acts as aligner. Due to accurate laboratory tests FIP INDUSTRIALE has been able to identify the most suitable materials and dimensioning to achieve the best performing mechanical characteristics. The Biblock system series is available for tunnels with various types of diameter. BOLTS FIP INDUSTRIALE can supply a broad range of bolts fo

Gaskets are necessary to guarantee watertightness of the tunnel and avoid water infiltration in the bridge segments. Almost 20 million metres of gaskets supplied for railway, underground, road and hydraulic tunnels prove FIP INDUSTRIALE technical skills and production capacities. FIP INDUSTRIALE gaskets are made of EPDM, CR-SBR, NBR and HYDROEXPANSIVE RUBBER. FIP INDUSTRIALE manufactures both compact gaskets with hardness from 50 to 80 Shore A, and foam gaskets with various densities. The gaskets can be supplied in continuous extrusion or in frames with 4 or 6 corners moulded to the profile. EPDM water-tight gasket. Durability and unchangeability over time of FIP INDUSTRIALE gaskets are guaranteed by the special rubber compounds used and by severe laboratory testing simulating actual service conditions. The dimensions of the gasket, the profile, the type of rubber and its physical and mechanical characteristics can be specified at the design stage based on the service conditions:
