Trenord railway underpass, Saronno

by

Then the excavation and casting of the Drytech waterproof concrete slab was carried out, resting on the bulkheads and prepared with the DRYset crack control elements. The whole operation took place in just three days, at the end of which the track was restored.

The procedure was therefore repeated on the other track. After another three days the line returned to full capacity, with both tracks open.

The excavation was then carried out under the slab, the casting of the platform floor of the underpass and finally the lining casting, directly against the micropiles.

When the concrete matured, joints, holes and programmed cracks were injected with DRYflex resin which, expanding, sealed them by pressure.

Drytech Engineering provided advice on aspects relating to waterproofing, collaborating with the structural engineer already in the design phase of the underpass.

Hotel Hilton, Como

by

Hilton Lake is the largest hotel on Como Lake.

Opened in 2018, it has 170 rooms, two restaurants, a spa with indoor pool, a state-of-the-art fitness center open 24 hours a day and a conference area divided into 6 modular spaces and a total capacity of 300 seats.

On the elegant rooftop on the top floor of the building, guests can enjoy the breathtaking view of the lake directly from an infinity pool – created by Drytech in a single waterproof concrete structure -, from the adjacent lounge bar with terrace overlooking the city gulf. or, on the opposite side, from the solarium with hydromassage.

The project by architects Dario Pietro Cazzaniga and Monica Limonta started with the redevelopment and renovation of two existing buildings: a former brick weaving house, which houses the entrance, reception and lounge bar Taffeta, and a rear body that has been completely redesigned on the large floor-to-ceiling windows of the rooms.

The two main bodies are connected by a modern glass structure that houses the lobby and reinterprets the lakeside tradition of greenhouses and winter gardens.

The whole structure, including the 21 suites, was furnished by the architects Cazzaniga and Limonta.

A global approach that is reflected in the elegant architectural and functional unity of the project and which places the structure at the top of the Lake Como hôtellerie.

Nuvola Lavazza, Turin

by

The Lavazza Cloud designed by Cino Zucchi Architetti and the historic buildings recovered by Cino Zucchi himself together with Picco Architetti, are an example of architecture that dialogues with the neighborhood, with time and with the environment.

Over time, the area affected by the intervention has hosted the activities of the Alta Italia Electric Company, Sip and finally Enel.

A historic production site surrounded by a boundary wall.

The large block was opened and transformed into a pedestrian square overlooked by all the spaces, both newly built – the new Lavazza business center – and recovered.

A place that becomes an integral part of both the road system and the life of the neighborhood, with the large square-garden and its premises and with the underground public parking.

The environment helped shape the height of the building, which varies on different sides from six to two floors, depending on the solar orientation and the surrounding buildings.

The metal pilasters and stringcourses form an external grid on the floor of the windows which, depending on the seasons and the same hours of the day, helps to shield or favor the penetration of sunlight.

The uninterrupted dialogue with the environment includes roofs covered by greenery, hanging gardens inserted between the offices and a sophisticated digital system that programs the environmental parameters – such as temperature and lighting – in relation to the times and methods in which the different spaces are used, so as to maximize living comfort and energy efficiency.

Vetropack water tower, Corsico

by

Drytech restored the water tower of the Vetropack plant in Corsico with injections of waterproofing resin carried out from the outside, without having to empty the barrel.

The fire-fighting water reserve was thus guaranteed to the continuous-cycle industrial plants and the company did not have to rent a tanker for the fire brigade.

With the Drytech system it is no longer necessary to dive into the barrels, with all the related logistical and safety implications.

For the intervention, Drytech technicians exploited a scaffolding already set up by a company to restore the external surface of the tower.

Normally the Drytech Rehabilitation System allows the practical use of aerial platforms, with a consequent saving on costs and time for setting up the scaffold.

Denitrification tanks, Bresso

by

The Bresso Niguarda treatment plant was equipped with a new denitrification basin of 10,800 m³.

Wastewater denitrification is a process for the removal of nitrogenous compounds present in solution by optionally heterotrophic bacteria.

The part of the plant where the process takes place is a rectangular tank divided into two chambers of equal size, connected only superficially, which allow the continuity of the treatment, even when one of them needs to be emptied for maintenance.

Being a single waterproof concrete structure, the Drytech tank has the advantage of allowing maintenance interventions carried out from inside the tanks and immediately verifiable.

Renovation with Ex-Post Drytech Tank, Italy

by

Due to an underestimation of the water table, the waterproofing of the underground in this prestigious residential complex was not planned.

Unfortunately, after the construction was completed, a peak of the seasonal water table flooded the -2 level, making the garages unusable.

At this point Drytech was involved to restore the underground.

The analysis of the structural and environmental situation by the Engineering has identified the best solution in the construction of an ex-post Drytech Tank.

The industrial floor built above the gravel filling was therefore demolished. The water table was brought under control with a well-point system.

We then proceeded to lay the cracking elements in the stalls and prepare the stalls / walls and stalls / columns joints with the DRYset Channel.

The numerous crossings produced by the well-points have also been suitably prepared for the waterproofing injection, once the concrete has matured.

The new waterproof concrete slab based on the Drytech recipe was then cast.

To ensure the height of the extrados, it was necessary to create the sealed platform and the industrial floor in a single fresh-on-fresh helicopter jet.

When the concrete has matured, Drytech has perfected the injection of programmed cracks, joints and crossings with DRYflex expansive resin.

Due to its elastic quality, the resin is re-injectable, so it guarantees the possibility of maintaining the system over the years.

The construction of the ex-post Drytech platform made it possible to waterproof the basements and to deliver the properties with the usable garages.

Intesa Sanpaolo tower, Turin

by

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.

Railway underpass, Vigevano

by

A new pedestrian underpass was built under the Vigevano station, which allows travelers 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.

Railway underpass, Albairate

by

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.

Prefabricated waterproof tanks, Loano

by

The fuel tanks of the service station of the new tourist port of Loano were built ashore by the company PB Lavori Marittimi of Ancona with the Drytech Tank technology.

The construction of prefabricated tanks has the advantage of a more practical processing and with a higher quality standard, since the jet in water often produces gravel nests, regardless of the expertise and care of the diving technicians.

Where transport does not constitute an obstacle, the prefabricated tank is therefore preferred.

The tanks were built on the dock of the shipyard area of ​​the new port of Loano and Drytech Engineering collaborated with the designer already in the design phase, for the aspects related to waterproofing and the problems of transporting the tanks.

Made of XS2 exposure class waterproof concrete (submerged constructions in a marine environment), the tanks were again injected on the ground with DRYflex acrylic resin, which waterproofed the joints and shrinkage cracks by pressure. We then proceeded to lift and launch by sinking.

The 4 tanks were then welded with a crowning casting. Also this joint, prepared with the DRYset injection channel, was waterproofed for its entire thickness with DRYflex resin. After emptying it was therefore possible to carry out the final testing.

The Drytech Tank as a whole, and the DRYflex resin in particular, must ensure impermeability from aggressive elements such as sea water.
