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

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:

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.

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 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.

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.

Load spreading pads protect the segments during installation on the feed front. The pads are made to measure, of elastomerised bitumen with the addition of SBS rubbers and polyester or fiberglass reinforcements. UAE - Abu Dhabi STEP T02.

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
