The railway underpass of Indipendenza street in Crema allows the passage of a road and a cycle path under the railway path.

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 f the railway underpass of Indipendenza street in Crema were prepared with DRYset injectable waterstop tapes.

A brutalist structure in red concrete makes the historic seat of the municipality of Bioggio contemporary.

Work of the architects Lorenzo Bronner and Luciana Bruno, the intervention added a large external staircase to the eastern façade, incorporated into a thin reinforced concrete frame that recalls the Venetian red of the nineteenth-century building.

A perfect connection between past and present, reiterated and at the same time modernized by the deep frames that define the window spaces. The constant module of the openings on the facades of the original body becomes asymmetrical and intermittent on the new facade, yet recognizable in the grid hinted at by the occasional openings.

The clear stringcourses of the original body connect to the frames of the glass walls that incorporate the new external staircase, establishing a further connection between the stylistic features of the two architectures.

In continuity with the concrete wall, the architects Bronner and Bruno designed a podium in which the large basement garage for police vehicles is located. The podium slab is covered with a large grassy surface that interacts with the brutalist façade.

Two external staircases in the same color as the structure allow access to the entrance level. The footboards of the steps were waterproofed with the Drycoat covering which, thanks to the flexibility of the quartz colour, made the stairs perfectly in tone and integrated with the rest of the intervention.

Industrial Water Clarifier, Genoa

by
An industrial clarifier

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.

The Scudo, Stabio

by
A building that produces environment.

A building that produces environment. It is the new frontier of construction, which extends the concept of sustainability to the regeneration of biodiversity, establishing an active and osmotic connection with the context.

The Scudo di Stabio by architect Giuseppe Rossi is Minergie-P-ECO certified and is the first residential building in Ticino built according to the Swiss Sustainable Construction Standard (SNBS 2.0 BUILDING – GOLD certified). For the innovative choices that characterize it, it was selected among the finalists of the Active House Awards 2022 in the Netherlands.

A sustainability that starts from the volumetric compactness of the structure, functional to the energy efficiency of the building. The construction consists of two systems. The first, in recycled reinforced concrete, concerns the basement, the ground floor and the central distribution volume.

The other consists of the two wooden macro-volumes, dedicated to the apartments distributed over two floors. Vitro-photovoltaic tiles are set on the suggestive cork roof: a renewable energy production system that combines functionality and design and makes the building self-sufficient.

The project also involved the outdoor spaces, planted with native hedges that attract birdlife with berries and acorns.

The vocation for dialogue with the context is also expressed through the promotion of shared and green mobility, thanks to the availability of electric bicycles and car parks with charging stations for cars.

Enzo Ferrari Museum, Modena

by

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.

Grand Hôtel des Iles Borromées, Stresa

by
La façade Art Nouveau du Grand Hôtel des Îles Borromées

In September 1918 a 19-year-old American soldier was wounded in the trenches and spent his convalescence in Stresa.

That boy is called Ernest Hemingway and, fascinated by the beauty of Lake Maggiore, he set part of his novel A Farewell to Arms – A Farewell to Arms, 1929 – there, making the Grand Hôtel des Iles Borromées famous throughout the world.

It is just one of the many connections with history that have built the legend of the great hotel, inaugurated in 1863.

With the opening of the Simplon railway tunnel, Stresa became a privileged destination for elite European tourism and, in 1919, was included in the sixth route of the Orient Express: the one which from London reaches Istanbul through Italy, via Milan, Venice and Trieste.

The Simplon Orient Express soon became the most successful route and getting off at Des Iles gave wealthy travelers their first evocative impact on the Bel Paese.

In over a century and a half of history, the Hôtel des Iles Borromeés has been able to adapt the concept of elegance to the evolution of times and tastes, without distorting its inimitable Art Nouveau style.

The new Spa was inaugurated in 2022, with wellness programs, saunas, Turkish baths, salt rooms, as well as indoor and outdoor swimming pools and hydromassage tubs, all made with the integral waterproofing of the Drytech Tank.

The speed of construction of the Drytech system allowed the Bellani company of Arona to remove the waterproofing activities from the work calendar, delivering the new structure in time for the opening of the grand season.

Drytech Engineering also designed the solution for a sensitive structural detail such as the passage between the internal and external swimming pool, subject to significant temperature variations depending on the season.

Ra Curta Residences, Montagnola

by
Ra Curta residences Project A++, Lugano

The project of the Ra Curta residences was born from the conformation of the land on which it stands.

The emerging architectural elements follow the natural morphological elements of the lot, so that the project is strongly rooted and in balance with the context

The translation of the blocks downstream and the different heights lie harmoniously on the natural terrain, guaranteeing maximum privacy and visual channels to the lake.

The 4 blocks that are mirrored, accentuating symmetries and proportions, are crossed by two stairways that become urban connections between the streets of Montagnola.

Large terraces emerge from the ground like horizontal blades, the edges of which are made of different materials that form suspended frames and light eaves.

Particular attention was paid to brightness, while still maintaining a high level of privacy.

Drytech created both the hanging swimming pools and the underground waterproof structures, including the long and elegant access corridor to the private garages of the properties.

Drytech Ex-Post tank for oil plant, Italy

by

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.

Beata Vergine Hospital, Mendrisio

by
The superficial grid of the Mendrisio regional hospital brings together the different distribution of spaces

The Mendrisio regional hospital is located in an area on the edge of the historic centre, characterized by the presence of buildings surrounded by majestic gardens.

The positioning of the hospital expansion aims first and foremost to strengthen this ensemble through the definition of a public space: an urban park capable of offering a spatial quality to the buildings that stand on this place.

The main architectural choices of the new wing, such as the porticoed ground floor and the design of the facade, derive largely from the particular condition of a hospital building surrounded by a public space.

The semi-underground rooms, the underground ones and the extension of the garage with 127 parking spaces created under the new square were created with the Drytech Tank system.

The facade seeks an adequate response to the public situation of the building, allowing an open view towards the outside but at the same time closure and appropriate discretion for those looking from outside.

Through the twisting of standard aluminum profiles, a precise identity is given to the building. This surface grid makes the different distribution of spaces unified.

Corso Como Place, Milano

by

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.
