Teatro Alla Scala, Milan

by

As part of the renovation and expansion of the Teatro Alla Scala in Milan designed by architect Mario Botta, the waterproofing of the scenic pit was carried out, with 850 m² of stalls and 2,500 of walls.

The Drytech Tank System was chosen because it made it possible to waterproof the tie rods of the unloaded floor.

It also saved about 90 days of work for the entire calendar of works because the waterproofing activities are independent and parallel to those of the construction site and are in fact removed from the Gantt chart.

A further saving of time and resources derives from the fact that the elevations of the Drytech tank are thrown directly against the micropiles, making the lining and the wall coincide.

The new stage tower rises 38 meters and the stage pit is 18 meters deep. The new structure behind the stage allows you to manage the sets of 3 shows at the same time.

Sophisticated stage machines allow you to completely change the show in just 6 minutes.

Allianz Isozaki Tower, Milan

by

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.

Hotel Il Sereno, Torno

by

The symbiosis between Il Sereno di Torno and Lake Como began right from the laying of the first stone. The design hotel has literally risen from the waters of the Lario.

The charming country road that leads to the hotel is in fact not passable by heavy vehicles, so all the material for the construction arrived by lake on board barges.

The dominus of this complex construction site was the architect Fabio Curcio Valentini, construction manager and coordinator of the architectural project of Patricia Urquiola, who also created the contemporary interior design of the Luxury Hotel.

The construction was consolidated with poles placed in the water, and the area dedicated to the technical systems was obtained by digging into the granite rock without using explosives, up to a depth of seven meters below the level of the lake and creating the waterproof structures with the Drytech Tank system.

The old dock was incorporated into the new building of four floors above ground and two underground floors.

The lake-front wing towards Como hosted the underground garage and the heated outdoor swimming pool, also a Drytech tank and covered in Brazilian karst stone.

Giusti Wine Cellar, Nervesa

by
The Giusti Wine cellar in Nervesa della Battaglia designed by architect Armando Guizzo

The new Giusti Wine cellar in Nervesa della Battaglia was designed by architect Armando Guizzo to tell a story of ties with the territory and harmony with nature.

Ermenegildo Giusti is a convinced supporter of viticulture that respects the environment and people. Giusti wanted a winery that plastically expressed the values of sustainability and integration.

The cellar is two thirds underground, while the emerged part integrates with the territory, not only architecturally but actually: the undulating roof with its rows is not an aesthetic exercise, but rather an authentic wine-growing area, structured to support the weight of the agricultural vehicles and which produces bunches exactly like the surrounding rows.

Particular attention was paid to the roofing, with an in-depth study of the materials used for growing the vines. First of all, the natural soil that covered the area before the construction site was excavated was restored on the roof.

Below this original soil, several layers of different natural materials were laid, including expanded clay, which in addition to ensuring the growth of the vines, make an important contribution to the energy saving of the building.

The entire hypogeum was created with a single waterproof Drytech Tank.

Porta Nuova, Milan

by

The masterplan of Milano Porta Nuova was signed by the Kohn Pedersen Fox studio of London, while the executive plan is the work of the Arquitectonica IC of Miami and m²P Associati of Milan, for the commissioning of Hines Italia and Galotti SpA.

3,000 m² are destined for the Municipality of Milan to make it a cultural center. The four underground levels, made with the Drytech Tank waterproofing system, house parking spaces for 2,000 cars.

Drytech has built 43,730 m² of waterproof underground structures with the White Tank System, collaborating with the designers of Arup Italia in Milan and coordinating with the CMB company for the preparatory activities for waterproofing which, being parallel to those of the construction site, are in fact been removed from the work calendar.

he new car park of Marina of Loano, one of the most interesting tourist ports in Mediterranean, has 400 parking spaces below sea level.

The new car park of Marina of Loano has 400 parking spaces below sea level.

Loano is one of the most interesting tourist ports in Italy and the Mediterranean for pleasure boating.

The expansion of the Marina involved a surface area of 358,000 m2 and involves the construction of over 1,200 berths, with the possibility of mooring boats up to 50 meters in length.

The port and city are served by a car park with 1000 parking spaces, of which 400 are underground. Or rather, submarines.

The underground car park of the Marina di Loano, created with the Drytech Tank System, drops 4 meters below sea level.

Sant’Ambrogio car park, Milan

by

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.

Milan subway restoration

by
renovation of some sections of the Milan Metro

Drytech carried out the renovation of some sections of the Milan Metro, during the night closure of the service, therefore without interfering with the normal circulation of trains.

The interventions were carried out with injections of DRYflex expanding resin in the joints between the floor and the inverted arch, for the entire thickness of the concrete structure of the tunnel.

DRYflex Resin is effective even in the presence of pressurized water. This made the intervention possible despite the huge extent of the infiltrations.

MM Line 2 was built between the 1960s and 1970s without waterproofing, because the water table was much deeper.

The closure of Milan’s manufacturing activities in the 1980s reduced water consumption and caused the groundwater level to rise up to the Line 2 tunnels.

The infiltrations were controlled by pumping systems active 24/7, but in periods of heavy rainfall some sections were still flooded.

It was therefore decided the renovation of some tunnels of the Milan Metro, carried out by Drytech during the night traffic closure.

Trains Workshop, Mestre

by

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.
