Prefabricated underpass, Crema

The railway underpass of Indipendenza street in Crema allows the passage of a road and a cycle path under the railway path. The work was carried out without interrupting the overlying passage of the trains.

The Drytech Tank made it possible to prefabricate the monolith near the tracks and push it to its final location with an excavation that gradually replaced it for the ground supporting the railway line.

Once positioned in place, the monolith was waterproofed in its critical points (cracks and joints) with DRYflex expanding resin injections.

Made ex-post, the waterproofing did not risk being damaged during the launching operations.

The expansion joints were prepared with DRYset injectable waterstop tapes.

The snow factory, Carosello of Livigno

Close to the Carosello 3000 station in Livigno Drytech has built the new 5,600 m³ water tank, which will feed the cannons for artificial snow.

The work, built in 5 months with a 2’175 m² Drytech Tank, is completely underground to have no impact on the Alpine panorama.

The practicality of the construction of the Drytech Tank makes the construction of these structures faster. Time is a decisive factor in any construction site, but it becomes even more important for applications conditioned by seasonality (the structure had to be ready in time for the opening of the ski season) and with a climate that reduces the useful building time to a few months.

Drytech Engineering has formulated a waterproof concrete suitable for environmental conditions, based on the characteristics of the aggregates present in the plant chosen by the Edil Dona company in Valdisotto, Sondrio.

The acrylic resin DRYflex, which waterproofs the details by pressure, is certified for use in structures in contact with drinking water, so it is safe for the environment and therefore perfectly suitable for use in a tank that feeds the guns of snow.

One of the main acceleration factors on the construction site is the control of shrinkage cracking.
In fact, the Drytech tank allows you to make continuous castings (the bed was cast in a single solution) because the cracks are induced by the Cracking Elements, which can also act as disposable formwork.

Industrial Water Clarifier, Genoa

An industrial clarifier receives wastewater laden with metals, hydrocarbons and other pollutants.

It separates these elements from water through mechanical and chemical processes.

It then conveys the clarified water to the sewage systems and retains the residual sludge from the purification.

The walls of a clarifier are therefore exposed to a series of more or less aggressive agents. Conversely, they must not release any material into the water, much less polluting.

The DRYflex resin – used to seal joints, crossings and cracks in the Drytech Tank – has this dual ability to resist aggressive agents (starting with salinity) and even be compatible with use in drinking water facilities.

It is important to emphasize that the resin saturates joints, cracks and crossings for the entire thickness of the structure.

In the case of the Genoa clarifier, the barrier opposite the water has a variable thickness from 30 to 120 cm, coinciding precisely with that of the structure.

On the other hand, the characteristic single structure of the Drytech tank allows direct and non-invasive access for any maintenance interventions, which are simple and immediately verifiable.
Moreover, without particular limitations on the use of the system.

As part of the construction of the Genoa plant, Drytech Engineering collaborated with the structural engineer already in the design phase, proposing solutions for waterproofing the critical points of the structure. Engineering also contributed to the definition of the recipe for controlled shrinkage waterproof concrete, based on the characteristics of the plant chosen by the client.

Corso Como Place, Milano

Corso Como Place represents the new frontier of smart building: a building model that combines energy efficiency and environmental sustainability with a new experience for users and an evolved concept of living well-being.

What makes the project even more special is that it starts from the renovation of a building from the 1960s.

The Pirellino, as it was called by the Milanesi, stands in the center of the new Milan of Gae Aulenti Square, Corso Como, Eataly and the Feltrinelli Foundation & Microsoft House.

An iconic and very central place, which has stimulated a revolutionary project.

Corso Como Place is a complete redevelopment project, symbol of an architectural and urban planning path that creates beauty without destroying the existing one, starting from the enhancement of the Tower designed by Francesco Diomede, Giuseppe and Carlo Rusconi Clerici, converted to modernity in the sign of innovation.

At its foot stands a Podium that draws an open square directly connected to Corso Como and the Porta Nuova district.

The environmental sustainability of the buildings is guaranteed by the Nearly Zero Energy Building international standard.

The photovoltaic system chosen for the structures, the use of geothermal energy, which covers over 65% of the annual requirement, and the high-performance facades with automatic solar shading devices, allow very high energy performance and maximum reduction of CO2 emissions.

Furthermore, the choice of the Drytech Tank for the hypogeum ensured the impermeability of the underground structure not only to water, but also to radon.

A smartphone application allows everyone to customize their work environment, by intervening on lighting, temperature and shading.

Underground parking can be booked in real time based on the availability of free parking spaces and the IoT sensors (the Internet of Things) will monitor the noise level of the offices and the quality of the air, to ensure comfort and well-being for users.

With a role as a hub for green mobility paths and green areas, as well as a driving force for the redevelopment of the area, Corso Como Place represents a beautiful example of how architecture and construction technology can transfer a historic building into the future.

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.

Allianz Isozaki Tower, Milan

The Isozaki Tower, inspired by Constantin Brancusi’s endless column, has become one of the symbols of the city. Designed by the Japanese architect Arada Isozaki together with the Italian architect Andrea Maffei, the skyscraper is the headquarters of Allianz in Italy.

The building, which can accommodate up to 3,800 people, is the tallest skyscraper in Italy by number of floors (50) and according to the highest occupied floor criterion (with its 207 m).

Drytech has designed the waterproofing of all the structures below the project ground level. The fire-fighting tanks, the system tunnels, the multi-lancet windows and the lower sections were therefore built with the Drytech Tank technology.

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.

Sant’Ambrogio car park, Milan

In Piazza Sant’Ambrogio, in Milan, the construction company Borio Mangiarotti S.p.A. built a five-storey underground car park.

Drytech has designed a waterproofing system for the diaphragm, based on Injectable Waterstop Tapes.

By making the diaphragm waterproof directly, it was not necessary to create the lining wall, thus increasing both the internal volume to comply with the legal limits, and the surface, or the parking spaces available.

The Injectable Waterstop Tape for the joints between the partitions of the diaphragms is a Drytech patent that makes it possible to maintain the joint with ex-post injections of resin, performed in the event of any infiltrations.

The Drytech tape is laid with a special sheet piling which acts as a formwork of the diaphragm wall.

The diaphragm of the parking lot that flanks the Milanese basilica drops to a depth of 22.70 meters and the laying of a sheet pile of this size required special care by the company’s technicians, to ensure perfect alignment of the joints.

At the end of the casting, the sheet pile is extracted, equipped with a new belt and repositioned for the casting of the next septum.

The re-injectability of the DRYflex resin guarantees the possibility of carrying out maintenance on the diaphragm at any time, by intervening from inside the structure, without excavation or demolition and, above all, without having to close the car park.

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.

Hotel Hilton, Como

Hilton Lake is the largest hotel on Como Lake.

Opened in 2018, it has 170 rooms, two restaurants, a spa with indoor pool, a state-of-the-art fitness center open 24 hours a day and a conference area divided into 6 modular spaces and a total capacity of 300 seats.

On the elegant rooftop on the top floor of the building, guests can enjoy the breathtaking view of the lake directly from an infinity pool – created by Drytech in a single waterproof concrete structure -, from the adjacent lounge bar with terrace overlooking the city gulf. or, on the opposite side, from the solarium with hydromassage.

The project by architects Dario Pietro Cazzaniga and Monica Limonta started with the redevelopment and renovation of two existing buildings: a former brick weaving house, which houses the entrance, reception and lounge bar Taffeta, and a rear body that has been completely redesigned on the large floor-to-ceiling windows of the rooms.

The two main bodies are connected by a modern glass structure that houses the lobby and reinterprets the lakeside tradition of greenhouses and winter gardens.

The whole structure, including the 21 suites, was furnished by the architects Cazzaniga and Limonta.

A global approach that is reflected in the elegant architectural and functional unity of the project and which places the structure at the top of the Lake Como hôtellerie.
