Bentonite or vulcanized rubber hydroexpansive gaskets can be used for traditional tunnels and for other structures, some of which can be complementary, like for example canals, dams, underpasses.

FIP INDUSTRIALE manufactures flat jacks for the activation of the coating of "active vault" segments, in the enlargement of tunnels with traffic.

FIP INDUSTRIALE guidance rods permit the correct positioning and circumferential centering of bridge segments. They also speed up the installation of every ring. They are glued to the short side of the bridge segment. Guidance rods manufactured in special unbreakable high-yield resistant plastic material and are therefore capable of withstanding high shear forces.

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

FIP INDUSTRIALE supplies and designs different types of inserts that can be fitted on every type of segment: Threaded inserts permit easy handling of bridge segments during erection; Inserts for injection facilitate injection of mortars or similar products at extrados level. Our range of products also includes combined inserts; Grounding inserts ensure the creation of an electric bridge, if required. Other types of special inserts have been designed and supplied in the past subject to prior specific examination. A type of combined insert.

For every project, FIP INDUSTRIALE always supplies the adhesive with the most suitable characteristics to meet site requirements. The broad range of adhesives for gluing gaskets, guidance rods and load spreading pads includes single-component, single-coating adhesives and thixotropic epoxy adhesives serving both as glue and as levelling agent for the groove concrete surface. Gasket gluing tests on concrete.

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:

They include a broad range of connection systems for bridge segments, gaskets, guidance rods, adhesives, packers, lifting-injection and grounding systems. FIP INDUSTRIALE can design, develop, test and supply any accessory for bridge segments, in every case in which tunnels are mechanically excavated by means of TBM mills which results in the use of prefabricated bridge segments. It can also supply flat jacks, bentonite or vulcanized rubber hydroexpansive gaskets for any type of tunnels and other structures which do not imply TBM mills TYPES: Watertight gaskets Adhesives Load spreading pads Inserts Biblock systems and bolts Guidance rods Flat jacks Hydroexpansive gaskets
