Drytech Tank waterproof underpasses

The Drytech Tank System allows you to create waterproof underpasses without interrupting traffic and, above all, without the risk of damaging the waterproofing

The Drytech Tank System allows the construction of waterproof underpasses without interrupting traffic and, above all, without the risk of damaging the waterproofing during construction and over time.

Commissioned by the Municipality of Muzzano, the Agnuzzo pedestrian underpass was built outside the carriageway, in Drytech waterproof concrete.

The joints have been prepared for resin injection with DRYset channels. The shrinkage cracks were checked with the DRYset crack elements.

The monolith was then pushed by jacks below the roadway, while the ground was progressively dug from the inside.

Once in place, the monolith was injected from the inside with DRYflex resin, whose elasticity and expansion qualities allow the waterproofing to adapt to the vibrations produced by higher traffic.

The ex-post waterproofing, by means of injections, on the one hand cannot be damaged during processing and, on the other hand, also allows to seal any cracks produced by the thrust stresses.

Waterproofing the basement of the Swiss Life park district, designed by Remo Leuzinger Architecture Studio with an important urban planning role.

The Swiss Life housing complex forms an archipelago that defines and enhances the view onto Via Lepori, consolidating the character of the urban axis of the artery and, at the same time, opens pedestrian passages that make an important part of the park accessible to the public.

The three articulated volumes of different heights integrate with the original valuable trees, proposing an image of buildings in the park. The irregular pentagonal plan of the main bodies overcomes the rigor of right angles, giving organicity to the volumes and fluidity to the orientation of the facades.

Each unit corresponds to a “Hortus conclusus”. Built with woven chestnut slat panels and galvanized iron wire, these nest-gardens reproduce the quiet and intimacy of a cloister, inside the park-neighborhood Swiss Life.

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.

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.

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.

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.

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.

Rehabilitation waterproofing of a subway

by
DRYflex resin injections to waterproof a road subway, without having to interrupt the upper railway traffic.

The rehabilitation waterproofing of a subway was carried out by Drytech with resin injections from the inside, without impeding the normal upper movement of trains.

A waterproof underpass without having to interrupt the upper railway traffic.

The renovation of the Albairate road underpass was necessary due to the failure of the existing bentonite system.

The structure was restored with DRYflex resin injections in the movement joints and in the casting joints.

The underpass began to leak a few months after opening.

Drytech intervened from inside the building, without structural demolitions or external excavations and, above all, without limitations to the normal circulation of trains on the Milan-Vigevano line.

Like any Drytech renovation, this too allowed immediate verification.
