Trains Workshop, Mestre

The futuristic RFI (Italian Railway Network) maintenance station in Mestre was designed to minimize the downtime of High Speed ​​Trains.

To make the washing and maintenance operations of the trains as fluid as possible, a structure has been created that allows trains to travel through the shed autonomously and for technicians to comfortably access all areas of the train, including the girth and roof.

250 meters of elevated track on columns were built for each of the 4 lanes of the workshop.

The 8,500 m² warehouse was fully fitted out with a removable rigid catenary, which allows the convoy to move without the towing of other tractors.

24 movable arms for each of the 4 internal tracks, equipped alternately with 12 motors, activate the displacement of the catenary once the train has reached the position, thus allowing to perform maintenance from above in total safety, through 7 service walkways elevated.

For girth operations, on the other hand, each raised aisle is equipped with an axle lowering system and Bertolotti opening tracks, which facilitate work on wheels and trolleys.

The equipment is completed by the mighty 10-tonne Demag overhead crane, with safety sensors.

In this regard, each track is also equipped with an individual safety system operated by sequential interlocking locks.

To connect the area to the railway network outside the shed, 5 km of tracks were laid, which create the access routes both to the internal tracks of the shed and to the two external tracks of the area used for washing the trains.

The internal installation was completed in record time in just 105 days!

The peculiarities of the Drytech Tank System contributed to this result.

The fact that the installation and injection activities of the Drytech System are parallel and independent from other construction site activities, and from the weather, has actually made it possible to eliminate waterproofing from the time schedule, accelerating the construction site as a whole.

Furthermore, the control of the shrinkage crack guaranteed by the Drytech Tank has considerably speeded up the casting operations.

AlpTransit Control Center, Pollegio

AlpTransit Polleggio Operation Center

The AlpTransit Polleggio Operation Center manages the railway traffic of the Gotthard and Monte Ceneri base tunnels.

Known as “The Periscope” for its futuristic architecture, the POC is one of the four SBB operating centers in Switzerland, together with the ultra-modern centers of Lausanne, Olten, Zurich.

Height and shape of the building are the architectural response to two functional constraints.

The POC marks and declares the entrance to the Gotthard base tunnel. It is a symbol.

To be perceived as such by the railway and the motorway it was developed in height.

The second constraint is the dimensional incompatibility between the control room and the type of an office building, which has led to accepting the contrast and expressing it in a radical way. Thus, the double-height slab of the control room is grafted onto a trunk of office space, arranged diagonally on the lot.

The AlpTransit Polleggio Operation Center therefore appears as a sculptural object animated by a twist between the two volumes.

Seen from a moving vehicle it transforms, changing its proportions and offering different states of balance.

Trenord railway underpass, Saronno

Then the excavation and casting of the Drytech waterproof concrete slab was carried out, resting on the bulkheads and prepared with the DRYset crack control elements. The whole operation took place in just three days, at the end of which the track was restored.

The procedure was therefore repeated on the other track. After another three days the line returned to full capacity, with both tracks open.

The excavation was then carried out under the slab, the casting of the platform floor of the underpass and finally the lining casting, directly against the micropiles.

When the concrete matured, joints, holes and programmed cracks were injected with DRYflex resin which, expanding, sealed them by pressure.

Drytech Engineering provided advice on aspects relating to waterproofing, collaborating with the structural engineer already in the design phase of the underpass.

Pedestrian underpass, Agnuzzo

The Drytech Tank System allows you to create waterproof underpasses without interrupting traffic and, above all, without the risk of damaging the waterproofing.

Commissioned by the Municipality of Muzzano, the Agnuzzo pedestrian underpass was built outside the carriageway, in Drytech waterproof concrete.

The joints have been prepared for resin injection with DRYset channels. The shrinkage cracks were checked with the DRYset crack elements.

The monolith was then pushed by jacks below the roadway, while the ground was progressively dug from the inside.

Once in place, the monolith was injected from the inside with DRYflex resin, whose elasticity and expansion qualities allow the waterproofing to adapt to the vibrations produced by higher traffic.

The ex-post waterproofing, by means of injections, on the one hand cannot be damaged during processing and, on the other hand, also allows to seal any cracks produced by the thrust stresses.

SBB CFS FFS train station, Lugano

An atrium that creates a new connection between the Lugano railway station and the urban fabric: a real portal that connects arriving and departing travelers with the rest of the city.

The icon of this project, which adapts the important urban hub to the increase in the flow of travelers and rationalizes their routes, is the large 1,600 square meter canopy suspended above the underground atrium.

The thin, airy roof creates a wallless atrium. From the train window you can thus admire a suggestive glimpse of the lake.

The atrium is lowered to the level of the main underpass, which connects the two parts of the city divided by the station, and through which you access the ramps that lead to the platforms.

The hypogeum is a waterproof structure made with the 2,700 m² Drytech Tank.

Intesa Sanpaolo tower, Turin

The Intesa Sanpaolo Tower in Turin confirms the coincidence between form and substance that characterized the entire work of architect Renzo Piano.

Just look at it to understand how it is made, how it works. Starting with the multiple relationships that he establishes with the environment, the city, the mountains on the horizon.

The east and west facades are characterized by tapered columns that support the 38 floors above ground, for a height of 166 meters.

A skin of mobile and transparent slats is suspended on these facades, which convey the air for cooling in summer and ensure thermal insulation in winter.

The skyscraper breathes and interacts with the environment, with the aim of consuming very little energy, which is moreover produced entirely from renewable sources.

The south side in fact entirely covered by a photovoltaic field of 1,600 square meters and the air conditioning system uses the heat exchange energy with the ground water. A rainwater collection system allows a saving of 48% of drinking water. Rain sensors and intelligent control units ensure controlled irrigation of green areas.

Lighting is also optimized through a louvered sunscreen system that modulates the amount of sunlight that penetrates the premises. At sunset the artificial lights come on automatically and gradually, according to the ephemeris.

The dialogue with the outside is not limited to the energy aspect, but also affects the social and urban plan. In addition to the offices for 2,000 Intesa Sanpaolo employees, the skyscraper has six floors dedicated to the public, with an auditorium, spaces for cultural events, a restaurant and a school. On the top of the Tower there is also the bioclimatic greenhouse and a panoramic café.

Started in December 2008, the first phase of the project ended in June 2011 with the construction of the foundations and the 6 underground floors with the top-down technique. Drytech has created all the tanks (internal and external) with the White Tank system as well as the treatment of the floor-diaphragm recovery joint along the entire perimeter of the basement, for a total linear development of 420 meters.

The underground floors house a car park with 300 parking spaces, technical rooms and the surprising underground garden, which also overlooks the kindergarten park.

At the foot of the skyscraper there is a park crossed by pedestrian paths that connect the surrounding avenues. On the large lawn, the kids give life to a theory of spontaneous and interminable football matches, making the doors with a pair of sweatshirts.

Railway underpass, Vigevano

A new pedestrian underpass was built under the Vigevano station, which allows travelers to safely access the platforms and connects the two districts on either side of the station.

The waterproof structure was designed and built with the Drytech Tank System, without interrupting railway traffic.

A suspended metal structure was created to support the tracks, closing one track at a time in rotation, diverting circulation to the others from time to time.

The underpass was made of watertight concrete based on the Drytech recipe, defined by Drytech Engineering on the basis of the aggregates present in the concrete mixing plant chosen by the Quadrio company.

The construction site did not affect the normal circulation of the trains and, in turn, Drytech did not interfere with the progress of the works, since its activities are parallel to the construction ones and are in fact removed from the work schedule.

Prefabricated waterproof tanks, Loano

The fuel tanks of the service station of the new tourist port of Loano were built ashore by the company PB Lavori Marittimi of Ancona with the Drytech Tank technology.

The construction of prefabricated tanks has the advantage of a more practical processing and with a higher quality standard, since the jet in water often produces gravel nests, regardless of the expertise and care of the diving technicians.

Where transport does not constitute an obstacle, the prefabricated tank is therefore preferred.

The tanks were built on the dock of the shipyard area of ​​the new port of Loano and Drytech Engineering collaborated with the designer already in the design phase, for the aspects related to waterproofing and the problems of transporting the tanks.

Made of XS2 exposure class waterproof concrete (submerged constructions in a marine environment), the tanks were again injected on the ground with DRYflex acrylic resin, which waterproofed the joints and shrinkage cracks by pressure. We then proceeded to lift and launch by sinking.

The 4 tanks were then welded with a crowning casting. Also this joint, prepared with the DRYset injection channel, was waterproofed for its entire thickness with DRYflex resin. After emptying it was therefore possible to carry out the final testing.

The Drytech Tank as a whole, and the DRYflex resin in particular, must ensure impermeability from aggressive elements such as sea water.
