Drytech has designed a special waterproof pump shaft that allows companies to create pumping points inside the bed.

Drytech has designed a special waterproof pump shaft that allows companies to create pumping points inside the bed.

The wells are made in the Bedano workshop, in Switzerland, and shipped to the construction site, wherever it is in the world, where they are prepared by the Drytech technician.

This is the case of the construction site opened directly in the North Sea, where 36 pump wells were installed, subsequently sealed and incorporated into the bed.

Once its function is exhausted, the Drytech pump well is waterproofed both externally and internally.

Once the casting is complete, the joint between the well and the bed is injected with DRYflex expansive resin, which seals the element by pressure, wrapping around the entire thickness of the bed.

Any water flows inside the well are instead rendered harmless by the lid sealed with gaskets both on the circumference of the well and on each of the sealing bolts.

The use of the Drytech System resulted in a saving of several weeks on the time required for the construction of the waterproof basement.

Waterproofing: Drytech Italy

by
The main façade of the Vira-Mezzovico Aqueduct.

The waterproofing of the new Vira-Mezzovico aqueduct basin was carried out with a complete Drytech Tank, including a waterproof slab.

The new water storage and supply basin is part of the General Plan of the Aqueduct of the Municipality of Vira-Mezzovico.

Set into the mountain slope to minimize its visual impact, the Drytech concrete structure is entirely waterproof, both to the water present in the ground and to that collected in the internal basins. Even the slabs, covered by the lawn, are in Drytech Tank, therefore also resistant to root development.

The perfect correspondence between structure and function of the Drytech Tank makes it not only a solid barrier to water (the waterproofing is as thick as the structure), but also a durable system, because it is predisposed to extraordinarily practical maintenance. To the point that, specifically, any intervention does not require emptying the reservoirs or even interrupting the service.

The modernization plan of Aqueduct of Vira-Mezzovico also affected the water network, renewed for flow and efficiency in all its twenty kilometers of underground pipes.

Drytech Engineering collaborated already in the design phase with Lucchini & Canepa Engineering, for all aspects relating to the waterproofing of the structure.

Waterproofing the underground garage

The beautiful building designed by Gieffe Studio has a north-facing façade with completely windows

Waterproofing the underground garage of a beautiful building with a completely windowed north façade.
Rules are made (also) to be broken.

The choice of Gieffe Studio’s project is dictated by the shape of the site and made possible by the performance of modern thermal insulation systems and materials.

The three-family villa is set in a sloping plot facing north-west, with a 270° view of the Cassarate valley, which ranges from the Denti della Vecchia to Lake Lugano.

Gieffe Studio has therefore designed ultra-panoramic window walls for the living areas, recessed and re-oriented with respect to the front of the building, thus guaranteeing the interiors natural lighting and correct sun protection in all seasons and favoring the view of the mountains on the north façade and of the lake on the west.

At street level there is the garage, connected to the floors by an internal lift, and built with a 700 m2 Drytech Tank. The main entrance is located on the south side, at the height of the third floor.

The rationalist design is made organic by the warm travertine stone cladding and the changing reflection of the mountains and the sky that is projected onto the large windows and the elegant glass railings.
The cut and the different tones of the stones lighten the large continuous wall on the mountain side, harmoniously inserting the volume into the gentle slope of the land.

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.

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.

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.

Waterproofing basement garage

A brutalist structure in red concrete makes the historic seat of the municipality of Bioggio contemporary. Architects Bronner and Bruno.

Waterproofing of the basement garage of the brutalist red concrete structure that makes the historic seat of the town hall 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.

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

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

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.

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.

Waterproofing recycled concrete basement

by
A building that produces environment.

Waterproofing the recycled concrete basement of an environmentally friendly building in Stabio.

The Shield is the new frontier in construction, extending 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.

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.
