Waterproofing infinity pool on rooftop

Hilton Lake is the largest hotel structure on Lake Como. The roof top is dominated by an infinity pool made of the waterproof Drytech White Tank structure.

The waterproofing of an infinity pool on the rooftop of the Hilton Hotel in Como was realised with a Drytech Tank made of waterproof concrete and then covered with stone.

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.

Waterproofing of the underground garage of Lavazza

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.

The waterproofing of the underground garage of the new Lavazza business centre in Turin is a Drytech Tank structure, which allowed the construction of the basement to be accelerated.

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.

Waterproofing the denitrification tanks

The walkway through the denitrification tanks made of the waterproof structure Drytech White Tank

Waterproofing the denitrification tanks of a water purifier is the most severe test for the watertightness of a system due to the particular aggressiveness of the waste water.

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.

Waterproofing of a pedestrian subway under an active railway line

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.

Restoration waterproofing of a subway

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

The restoration 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 restoration waterproofing 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 restoration, this too allowed immediate verification.

Waterproofing of tanks in wastewater treatment plants

The Rozzano wastewater treatment tanks of the Rozzano wastewater treatment plant are made of the waterproof structure Drytech White Tank.

The waterproofing of tanks in wastewater treatment plants presents a double challenge for watertight systems.

This type of structure must in fact guarantee double impermeability: to the external water table and, obviously, to the water treated inside the tank.

The Rozzano Purification Plant is also located on a narrow strip of land between the southern course of the Lambro river on one side and a canal on the other, in the south-east area of ​​the Smeraldino Oasis.

So the theme of the watertightness of the work is, if possible, even more sensitive due to the environmental implications.

Made by the Intesa Costruzioni company in collaboration with Drytech, the new purification tank was built in just 120 days with the Drytech Tank system.

The waterproof concrete was formulated by Drytech Engineering based on the characteristics of the system chosen by the construction company, with the aim of ensuring, in addition to watertightness, chemical resistance to urban waste.

Similar resistance is obviously required for DRYflex resin, which, being expanding, waterproofs joints, cracks and crossings by pressure.

The resin is injected along the entire thickness of the structure, so it opposes the water with a corresponding barrier.

Furthermore, the compatibility of DRYflex with drinking water – certified by compliance with BS 6920-1: 2000 – allows for guaranteed use in structures in contact with drinking water.

The new tank of the Rozzano Purification Plant, which came into operation in February 2019, has a capacity of 1,700 m³ and treats a maximum flow rate of 360 m³ / h.
