The FAMA Anti-Seismic Device was first installed in 2016, in the Thessaloniki metro project in Greece. It was officially presented at WTC 2017 in Bergen, Norway.
The special features of the anti-seismic device are:
1. Timely analysis of technical characteristics of products
2. Quality assurance plan
3. Data sheets
4. Technical reports of qualification tests
5. Product Drawings
6. Gaskets and accessories installation manual
7. Case histories

10. Site start-up assistance
11. Measurement of test rings, formwork and segments
12. Control of product behaviour
Crack Inducer is a device produced in plastic material designed to be easily and quickly fixed to the segment reinforcement cage prior to its positioning in the formwork and then be incorporated into the finished segment.
The purpose of the Crack Inducer is to cause controlled cracking in the segment concrete by generating weakened areas in the segment section at a specific location.
In this way it helps to avoid cracks in the concrete in areas of the segment considered critical.
The Crack Inducer is equipped with a position adjustment system to ensure alignment with the intrados and extrados surface of the segment.
FAMA has committed to finding a solution that may counter the negative impact of contaminants and aggressive agents contained mostly in the tunnels for drainage of urban water and wastewater.
FAMA has therefore designed and developed PROTEX which is an innovative system for the protection of the segment and hydraulic sealing of tunnels in contaminated environments.
The system consists of an HDPE layer on the segment intrados which is integrated to the anchored sealing gasket, thus providing a complete protection and sealing of the segments also along the joints.
PROTEX also includes a sealing gasket positioned on the extrados which provides, with the gasket positioned on the intrados, a double sealing level and prevents the risk of the surrounding soil erosion in the long term. The use of the double sealing includes the adoption of a cross-gasket to confine infiltrations. This represents a further innovation as the cross-gasket is anchored to the concrete as well.
At last, the extrados surface of the segment is protected against external agents by a coating treatment.
PROTEX is an innovative solution consisting of five levels of sealing that allows completion of the tunnel lining during the installation phase, eliminating all the laborious secondary activities performed until now in the tunnel to obtain its sealing. At the same time, costs and construction time are reduced in the short and long term.
The durability of the work is thus ensured through the protection of the concrete and hydraulic sealing from inside and outside of the tunnel.
AI FOR PROCESS CONTROL
A solution to integrate all kind of tunnels with the fiber optic cable monitoring system augmented with AI Process Control.
A solution for pipe jackings tunnels, which avoid the welding procedure during the construction of the tunnel.
Special system for adjacent ring connection, including steel tie rods embedded into the segments and connected in series by means of special centering pins that also ensure the correct alignment of the segments.
