The waterproofing of cellar and walls in contact with the ground

by
Designed with the expressive power of a sculpture, the Chienbergreben private house in Gelterkinden follows the slope of the land, on the border between the town and the agricultural area.

The waterproofing of the cellar and the walls in contact with the ground was realised with the Drytech Tank waterproof concrete structure, in perfect coherence with the villa’s architecture.

Designed with the expressive power of a sculpture, the Chienbergreben private house in Gelterkinden follows the slope of the land, on the border between the town and the agricultural area.

The underground structures were built with the Drytech Tank System, which made them impermeable to both groundwater and slope water.

The adoption of the Drytech System, which provides for a single waterproof concrete structure, has allowed the project to respect the figure that defines it architecturally even in the underground part.

The entire structure of the building is in fact made of exposed concrete with disposable horizontal formwork: inside as well as outside.

Waterproofing of the communal car park

by
The dialects connecting the three buildings of the Baden Ruetihof residential complex

The waterproofing of the communal car park of a residential complex was realised with a Drytech Tank designed according to the different loads insisting on the slab, at the buildings or green areas.

The movement joints placed in correspondence with the load changes to avoid cracks were sealed with special DRYset waterstop tapes, injected with DRYflex expanding resin, which made the justs themselves waterproof for the entire thickness of the underground structure.

The three buildings that make up the residential complex crown the communal garden, which also houses play areas and green spaces. The arrangement of the three bodies allows each residential unit to have a view and independence that guarantee absolute privacy.

Thanks to the southern orientation of the living spaces, the lounge areas and the elegant loggias and terraces guarantee optimal exposure to the sun.

The underground garage of the SPZ complex made with the waterproof structure Drytech White Tank

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.

Waterproofing underground atrium of railway station

by
The large canopy protecting the underground atrium connecting Lugano's railway station to the city.

Drytech realised the waterproofing of the underground atrium that creates a new connection between the Lugano railway station and the urban fabric: a veritable portal that connects arriving and departing travellers with the rest of the city.

The icon of this project, which adapts the important urban hub to the increase in the flow of travelers and rationalizes their routes, is the large 1,600 square meter canopy suspended above the underground atrium.

The thin, airy roof creates a wallless atrium. From the train window you can thus admire a suggestive glimpse of the lake.

The atrium is lowered to the level of the main underpass, which connects the two parts of the city divided by the station, and through which you access the ramps that lead to the platforms.

The hypogeum is a waterproof structure made with the 2,700 m² Drytech Tank.

Waterproofing of a automotive plant

by
The new Gleason headquarters in Studen

The waterproofing of the basement level of a large, modern automotive plant was realised with the Drytech White Tank system.

The building is used partly for offices and partly as a large production area for the Studen branch of GLEASON-PFAUTER Maschinenfabrik GmbH.

Technologically sophisticated gear hobbing machines for the production of precision gears for the worldwide automotive industry are manufactured here.

The large volume is flooded with light and has flexible space management.

Drytech Tank waterproofing has reduced the construction time of the industrial complex.

The waterproofing of the Intesa Sanpaolo skyscraper

by
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 Läderach chocolate factory

by
The Läderach site is bordered by a river, which is why the basement was built with the waterproof structure Drytech White Tank.

Drytech carried out the waterproofing of the new extension of the Läderach chocolate factory, which was built near a water course.

Since 1999, Läderach (Schweiz) AG, which has long since gained a worldwide reputation, has expanded almost every year by adding extensions, extensions and basements to its headquarters in Ennenda.

Leuzinger Architektur AG from Glarus designed and realised all the new buildings.

The latest is a new four-storey production hall, on the ground floor of which a new staff restaurant has opened.

Waterproofing of a pedestrian subway under an active railway line

by
A new pedestrian underpass was built under the Vigevano station, which allows travellers to safely access the platforms and connects the two districts on either side of the station.

Drytech carried out the waterproofing of a pedestrian subway in the Vigevano station built under an active railway line.

A new pedestrian underpass was built under the Vigevano railway station, which allows travellers to safely access the platforms and connects the two districts on either side of the station.

The waterproof structure was designed and built with the Drytech Tank System, without interrupting railway traffic.

A suspended metal structure was created to support the tracks, closing one track at a time in rotation, diverting circulation to the others from time to time.

The underpass was made of watertight concrete based on the Drytech recipe, defined by Drytech Engineering on the basis of the aggregates present in the concrete mixing plant chosen by the Quadrio company.

The construction site did not affect the normal circulation of the trains and, in turn, Drytech did not interfere with the progress of the works, since its activities are parallel to the construction ones and are in fact removed from the work schedule.

Waterproofing of Tissot Arena

by
Vista aerea della Tissot Arena di Bienne, con lo stadio di calcio, la pista di hockey e il centro commerciale.

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.
