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.

Reka Village, Albonago

Infinity pool of the Reka holiday village in Albonago, overlooking the Gulf of Lugano

“Making holidays and free time accessible to all”: it was with this objective that the Swiss Travel Fund (Reka) was founded in 1939, founded by visionary entrepreneurs, trade unions and tourism and transport companies. At the time, travel and holidays were prerogative of an elite.

Reka was created with the aim of making them accessible to an ever-increasing number of families, initially with a targeted savings system, then by developing its own holiday offers at affordable prices.

Reka has expanded and reconfigured the tourist village of Albonago with an investment of 33 million francs, creating 49 apartments, two hotel rooms, a tavern/pizzeria, a panoramic swimming pool, a wellness area, a bicycle station, areas for barbecues and playgrounds, for approximately 270 guests.

Drytech created all the waterproof structures of the car park, underground areas, swimming pools and wellness area.

One of the symbols of the Reka village is undoubtedly the infinity pool overlooking Lake Ceresio, with an incomparable view that embraces the entire Gulf of Lugano, the iconic Mount San Salvatore and extends to the horizon as far as Malcantone. A privilege truly available to all families.

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.

Enzo Ferrari Museum, Modena

The Enzo Ferrari Museum in Modena is an engaging hymn to the myth of the car and the architectural manifesto of Jan Kaplicky: the Czech architect who founded the Future System in London.

The Mef can count on an area of ​​6’000 m², of which 4’400 are intended for exhibitions. The Museum is a car hood that emerges powerful from the ground. In Kaplicky’s style, the height is contained to establish a harmonious relationship with Ferrari’s birthplace, without however attenuating the evocative force of the new structure.

The exhibition spaces were developed in the basement, creating a waterproof structure of 5’850 m² with the Drytech Tank System.

Access to the museum is through an imposing curved glass wall, whose inclined plane is bisected by a series of fins that resemble the radiator of a custom-built car.

The exhibition spaces are accessed from the hall through two inclined platforms, going down to a depth of 5 meters

“Spaces defined by eight edges are not necessary, they are not mandatory”. One of Kaplicky’s famous phrases expresses well the spirit of the project, to whose sinuous lines the flexibility of the Drytech tank has been perfectly adapted.

The design phase saw an intense collaboration with Drytech Engineering to define the waterproofing solutions for the unprecedented construction details proposed by the particular shape of the basement.

Drytech Ex-Post tank for oil plant, Italy

A valve park sorts the crude oil unloaded from tankers to storage tanks.

In the specific case of the plant’s leaks in the ground, it was necessary and urgent to restore it, but without the possibility of interrupting its activity.

It was therefore decided to create an impermeable tank below the system of valves, which had been placed in contact with the ground.

With an almost archaeological approach, the ground beneath the plant was excavated by gradually inserting supports to the pipelines.

Then we proceeded to the casting of the drytech waterproof concrete slab and walls and, when the casting was ripe, the waterproofing injection of DRYflex resin in the programmed cracks, in the construction joints and in the crossings, including the pipe supports, which were left in place.

The intervention, designed and coordinated by Drytech Engineering, restored the system to safety and made it definitively accessible for maintenance.

Teatro Alla Scala, Milan

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.

Mantegazza Palace, Lugano

Drytech Tank system for the 5 floors of the underground car park of Palazzo Mantegazza, 15 meters from the lake, in the presence of a water table of 18.80 meters.

The basement was built in underlay, using the hanging formwork technique: after the completion of the diaphragm walls, the slab of the ground level is cast, leaving openings through which it is possible to dig up to the level of the slab -1.

Then the formwork already used for the zero slab is lowered and, once it has reached level -1, the new slab is cast on it. And so on up to the bed, at level -5.

The walls of the Drytech Tank are made directly against the diaphragm, obtaining both the lining and the wall itself in a single casting.

Hotel Il Sereno, Torno

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.

Branca Crescent, Melide

There are only two ways to build a waterproof structure directly in water: either the classic double tank, or the single tank of the Drytech Tank technology.

The undergrounds of the Villa Branca Residence in Melide, on the banks of the Ceresio, were built with this system.

A luxurious crescent consisting of 16 apartments and 5 penthouses, with terraces, roof gardens, whirlpools and parking below the lake level.

In addition to allowing underwater installation, the Drytech tank ensured compliance with the internal volumes envisaged in the project, being a single waterproof concrete structure.

Drytech Engineering has defined the recipe for waterproof underwater concrete. As the casting matured, the construction details were waterproofed with the injection of DRYflex resin, effective despite the presence of water outside the new tanks.

Port parking, Loano

400 parking spaces below sea level.

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

The expansion affected an area of 358,000 m² and involves the construction of over 1200 berths, with the possibility of mooring boats up to 50 meters in length.

The port and the city are served by a car park with 1,000 spaces, 400 of which are underground. Indeed, submarines.

The underground car park, built with the Drytech Tank System, in fact drops 4 meters below sea level.
