Residence du Parc is located in a clearing in the Montagnola wood, on the Golden Hill overlooking Lugano.

A private park of 6,000 m2 with an outdoor swimming pool and views of the surrounding mountains.

The residence has two underground levels which house the garage on -1 and -2 laundries, cellars and technical rooms.

On the ground floor, in addition to the main entrance, there is the SPA and fitness area.

The location and development of the building adapt to the morphological profile of the land and relate to the neighboring maps to produce the maximum possible integration with the surrounding natural environment and with the solar arc.

Drytech has built the underground waterproof structures in exposed concrete and the swimming pools with the Drytech Tank system.

Waterproofing the underground level

With the Residenza Bella, Locarno has a new landmark that characterizes one of the main entrances to the city.

With the Residenza Bella Locarno has a new landmark that characterizes one of the main entrances to the city.

The facades punctuated by the grid of windows, the entrances created in the corners cut at the base, the suggestive stone of the facades which interacts vibrantly with the solar arch, the dynamic and surprising shape of the profile: everything contributes to the powerful originality of this residential and commercial building, designed by architects Filippo Floriani and Marco Strozzi.

But only by reaching the south side does one discover that it has an extra façade.
In fact, part of the roof is actually a series of semi-covered terraces interspersed with green pools. The tops of the plants emerge from the profile of the pitch, giving organicity to the structure.

Designed around the needs of those who live there, Residenza Bella of Locarno relies on careful construction, the choice of materials and the advantages of home automation for excellent energy performance, which also allows the management costs of the individual apartments to be contained.

The parking spaces are equipped with charging stations for latest generation electric cars and the Drytech Tank underground structure also guarantees impermeability to radon, for an architecture that manages to combine beauty, character and living well-being.

Drytech realised the waterproofing of the underground car park of the Schweizer Paraplegiker-Stiftung in Nottwil, on the banks of Lake Sempach.



Due to the presence of a significant water table, the large underground car park and all underground rooms were constructed with Drytech Tank waterproofing.

The car park of the Schweizer Paraplegiker-Stiftung shares an entrance with the underground car park of the “Sempachersee” hotel.

Car park D has 242 parking spaces on two floors, 31 of which are specially designed for wheelchair users.

As part of the construction of the new Swiss Paraplegic Centre, a practical and functional connection to the Guido A. Zäch Institute was also created.

The waterproofing of the Intesa Sanpaolo skyscraper

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

The waterproofing of the Intesa Sanpaolo skyscraper in Turin with the Drytech Tank system has made the perimeter joint between the raft and diaphragm watertight, among other structures.

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.

Waterproofing the underground garage

Architectural detail of the loggia of the Municipal House of Cadempino

Waterproofing the underground garage of the Cadempino town hall, designed by Antonio and Luca Antorini Architetti.

The new Municipal House of Cadempino is the seat of the city administration, but it is also many other things for the citizens. It is first of all a square, or an agora: in the Hellenic sense the main place of democracy, heart of the polis and seat of the assemblies.

This large open space, which from an architectural point of view communicates with the volumes, enhancing them through the contrast between empty and full, from an urban planning point of view acts as a catalyst and multiplier of meeting opportunities, both organized and spontaneous.

The square is also an arena: the steps that define the west side host the public for en plein air shows or events. The hope is that it will also be colonized and chosen as a wall by the kids of the town, but these are imponderable dynamics on which architecture can affect up to a certain point.

The space is delimited to the north by the large multi-purpose room and to the east by the municipal warehouse, while the main building, just set back, characterizes the square with a spectacular loggia that lightens its volume, and on which Lorenzo’s mobile sculpture vibrates Change.

The basement houses two car parks with charging stations for electric cars.

The entrance to the Municipal House of Cadempino is created in a deep setback compared to the main facade, which also in this case the void gives lightness to the structure.

The three levels of the main building develop around a tree that grows in a winter garden created in the center of the structure.

Vital fulcrum of the building, visible from each level at a different height, the cork oak takes on an engaging symbolic value, in which democracy can be seen as a good to be cultivated with everyone’s contribution.

The waterproofing of the underground structures of the Tissot Arena, starting with the underground car park, was realised with the Drytech Tank system.

The multifunctional sports and cultural complex is unique in Switzerland in that it combines a football stadium, an ice hockey stadium, an ice rink, a football training ground and a curling hall under the same roof.



In mid-2016, three more outdoor training grounds were completed to complete the overall stadium facilities. Inside, there are also large commercial areas, cinemas and a large multi-storey car park built with the waterproof concrete structure of the Drytech Tank.



The flexibility of the rooms also allows the stadium to host cultural events of all kinds, from concerts to conferences, allowing the facility to be used every day of the week.



In addition, Energie-Service Biel operates the world’s largest stadium-integrated solar power plant on the roof of the Tissot Arena.

Waterproofing of an underground wine cellar

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

For the waterproofing of an underground wine cellar, a total Drytech Tank was built, as the roof is also covered by the vineyard.

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.

Abdichtung historischer Gebäude mit Steinmauern

by
The interior of the new headquarters of the Dand Habitat Foundation in Basel, renovated by Kräuchi Architects.

The waterproofing of historic buildings with stone walls and their integration with new waterproof concrete structures is an issue that Drytech Tank solves with effective, integrated solutions.

The Dand Habitat Foundation, which builds quality and affordable housing in Basel, purchased nine historic buildings in Kleinbasel to make them its headquarters.

Basel-based Kräuchi Architekten designed the renovation by combining the various buildings, with their different levels and floors, into a unified whole, under the supervision of the Basel Office for the Preservation of Historic Monuments.

Drytech first sealed the perimeter of the stone walls with a horizontal chemical barrier to prevent rising damp. It then built a waterproof concrete slab and sealed the joint with the stone walls with injections of DRYflex expanding resin, ensuring the total watertightness of the basement.
