Waterproofing buried podium

by
An architectural detail that alludes to the battlements of the ancient city walls and breaks up the composed monumentality of the building.

The waterproofing of the partially buried podium of the Torricella-Taverne school is made with a Drytech Tank.

The construction of the Torricella-Taverne nursery school is part of the overall reorganization of an area in which the construction of various public, scholastic and sporting works is planned.

The Celoria Architects studio has translated the constraint represented by an existing wall into a resource, which, by touching the individual elements present in the area, defines their mutual relationships.

The wall has in fact become the main subject of the intervention, constituting the base of the building and the site of the pedestrian walkway that leads to the school and connects to the sports fields via a ramp.

The three remaining sides of the podium are underground and house the technical and service rooms in a waterproof Drytech Tank structure.

The planimetric organization of the building interprets the functional indications relating to school buildings, with the aim of optimizing circulation spaces, reducing distribution to a minimum and eliminating corridors.

The abstract composition of the volume is however softened by the introduction of some elements somehow extraneous to this composed monumentality, which allude to ancient bastions characterizing their formal expression. 

Even if the final touch of tenderness to the Torricella-Taverne nursery school is given by the row of small colored scooters parked under the loggia.

Waterproofing underground tunnel

by
Cunicolo AIL Agno-Bioggio

Waterproofing with the Drytech Tank structure of an underground tunnel that runs alongside a river and at one point passes under the bed of a tributary.

The AIL Agno-Bioggio tunnel for high voltage systems runs alongside the Vedeggio river for 4 km and, in a central stretch, is also bordered by the Prati Maggiori canal. Precisely at this point the route of the structure crosses the Riale Roncaccio drainage canal.

To overcome it, the tunnel dives further below the riverbed up to -5 meters from the ground level. Due to the particularly delicate position exposed to multiple water pressures, this section of the tunnel was created with a total Drytech Tank: foundation, walls and slab.

The Drytech Tank structure of the AIL Agno-Bioggio tunnel has a thickness between 30 and 40 cm and the joints have been waterproofed with injections of DRYflex expanding resin.

By sealing the entire thickness of the joint, the resin also protects the reinforcing bars, because it keeps water completely outside the concrete. In the event of any infiltrations, the system provides practical and easily manageable maintenance from inside the structure, without interruptions to the service.

The real possibility of carrying out maintenance contributes to the main quality of waterproofing: which is to prevent water from entering for the entire life of the work, i.e. for 50 – 100 years in the case of civil engineering structures, as prescribed by SIA 272.

Waterproofing the double underground gymnasium

by
The CPC double gym in Chiasso is the victory of lightness over weight, interaction over separation, flexibility over rigidity.

Waterproofing the double underground gymnasium, designed by architects Baserga and Mozzetti in fair-faced concrete.

The CPC double gym in Chiasso is the victory of lightness over weight, interaction over separation, flexibility over rigidity.

The duality between the podium and the covering volume of the room is defined by a detachment, produced by a punctual support on all four sides.

Through this suspension, the monolithic volume appears very light, to the point of seeming to be held back – rather than supported – by the four lateral Vs.

The detachment connects the interior space with the urban and natural elements that surround the gym. An interaction that places it in the context of the school and cultural campus, weaving various relationships with the peculiar elements of the place.

The building reacts to different situations and topographical differences. To the north it has an access terrace, in relation to the school buildings and access from the public car park. To the south, a flight of steps in relation to the small garden.

A delimitation of the road field and the existing square to the east. Finally, it is at the same level as the m.a.x Museum and the Spazio Officina, sharing their public vocation.

The podium is a Drytech tank. The insulation of the internal facades is protected by an exposed wooden strip in the lower part and by an acoustic paneling in the upper part.

From an energy point of view, the building meets the criteria of the Minergie standard.

Waterproofing a five-storey underground car park

by
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.

Waterproofing a five-storey underground car park below the level of the lake, with a water table of 18.80 metres.

The underground parking garage of Palazzo Mantegazza in Lugano was built on the lakeshore underwater, using the hanging formwork technique: after the completion of the diaphragm walls, the ground floor slab is cast, leaving openings through which excavation is carried out down to the level of 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.

Waterproofing of the underground gymnasium

by
The new underground gymnasium of the Massagno school, made with Drytech White Tank waterproofing

The waterproofing of the underground gymnasium of the Massagno primary school with the Drytech Tank structure made it impermeable to both water and radon.

This is the story of a beautiful elementary school from the 1960s that wants to continue to be beautiful in the new millennium. Where beautiful means adequate to the needs of modern pedagogy.

With this objective, the project by the Durisch + Nolli and Giraudi Radczuweit Architetti studios proposed the integral maintenance of the body of the school designed sixty years ago by Arch. Finzi, updating it through a process of reorganization, adaptation and expansion.

The spaces have been rethought on the needs of contemporary teaching, which requires larger classrooms to allow for dynamic teaching, with flexible spaces divided into different areas of activity.

The school complex was then expanded and completed with the construction of a double gymnasium and a canteen for pupils and teachers.

The double gymnasium dug into the ground made it possible to maintain a proportionate volume with the school building.

The hypogeum consists of a 4,000 m² Drytech Tank structure, impermeable to both water and radon.

The roof of the gymnasium, on which the new school canteen also stands, is a completely accessible space: a large public square also for the use of the population.

Among the different access routes to the level, the long staircase perfectly camouflaged in the architectural lines of the south facade stands out for its architectural quality.

The complex is presented as an open system connected with the city, with which it dialogues and interacts beyond the educational function.

The outdoor public spaces are in fact characterized by a great variety of themed places: from the birch park to the basketball court, from the lavender hanging planter to the long pool / fountain that borders the canteen square on one side.

But the school-city integration is confirmed by the extensive mending of the pedestrian connections that characterize the urban fabric of Massagno.

The area is permeable and inclusive and invites to be crossed because it offers direct and safe routes.

The school becomes a daily presence for the whole community.

Waterproofing of the underground passage

by
Insertion of waterstop tape in the cut made in the existing wall

The waterproofing of the underground passage connecting the new body to the main factory was realised with DRYset Injectable Waterstop Tape for movement joints.

The addition of a new body to the building of the Frigerio company in Locarno required the opening of a passage between the existing building and the new one.

The underground connection was made waterproof by inserting a continuous waterstop tape in the movement joint between the two bodies.

The DRYset injectable Waterstop Tape adds to the mechanical barrier function of traditional tapes the possibility of maintaining the joint over time, with possible re-injections of DRYflex expansive resin.

The profile of the Waterstop DRYset tape is in fact equipped with two micro-perforated ducts, through which the waterproofing resin can be injected and re-injected.

The tape was prepared in the Drytech laboratory and subjected to joint tightness tests before installation.

Access to the belt for any maintenance of the joint is guaranteed by cannulae accessible from the intrados of the building.

waterproofing of the AET headquarter

by
The new administrative headquarters of AET in Monte Carasso (the Ticino Energy Company) produces more energy than it consumes.
The waterproofing of the Azienda Elettrica Ticinese headquarters with the Drytech Tank system is consistent with AET’s mission.

The new administrative headquarters of AET in Monte Carasso (the Ticino Energy Company) produces more energy than it consumes.

On the one hand it boasts maximum energy efficiency in every technical component inside the building, on the other it produces energy entirely derived from renewable sources.

A positive energy balance, consistent with the corporate mission, which makes it the public building with the best energy performance in the Canton.

Designed by architects Lukas Meyer, Ira Piattini and Francesco Fallavollita, the new administrative headquarters of the Ticinese Electric Company appears impenetrable or transparent, simply matching the point of view.

The core of the building is in fact set back from the modular concrete grid facade. What a surprising optical effect from the outside translates into visual comfort on the inside: the offices are in fact flooded with mostly indirect natural light.

The site is lapped by the Ticino river and a stretch of water has been created between the existing building and the new one.

The underground structure was therefore built with the Drytech Tank system: a waterproof construction of 1,190 m², which houses the technical rooms, changing rooms, warehouses and the AET general archive.

Waterproofing of the underground cinema halls

by
The red carpet of the 70th Locarno Film Festival inaugurated the new cinema building. A screen of movable tiles designed by the London-based architecture firm AZPML rationalises the lines of the façade, while at the same time enhancing the original three-volume profile.

The waterproofing of the underground cinema halls of the Palazzo del Cinema di Locarno and all the basement rooms was carried out with the Drytech Tank within existing perimeter walls.

The new cinema building in Locarno was born from the transformation of the historic Palazzo Scolastico, designed in 1892 by the architect Ferdinando Bernasconi.

The London-based architectural firm AZPML has capitalized on the existing structure for identity, cultural and environmental reasons.

A screen of movable tiles rationalizes the lines of the facade, but at the same time enhances the original three-volume profile.

The intervention also involves the Remo Rossi square, transformed into a large red carpet perfectly connected to the surrounding street web.

Inaugurated on the occasion of the 70th edition of the Locarno Festival, the Palazzo del Cinema has three avant-garde screening rooms, two of which with 142 seats each, located between the basement and the ground floor, and one with 500 seats on the second floor.

The two underground rooms and all the other service structures below the ground level were built with the Drytech Tank System.

The window sills, on the other hand, are protected with the Drycoat waterproof covering which, with its reduced thickness, does not alter the purity of the architectural lines.

The vibrant covering of gold tiles is iconic. Ethereal, changeable, dynamic: it is architecture, but it looks like cinema.

Drytech Tank waterproof underpasses

by
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.

Residence du Parc is located in a clearing in the Montagnola wood, on the Golden Hill overlooking Lugano.

The waterproofing of the underground garage, the technical rooms and the swimming pool of the Residenza Eos du Parc in Montagnola was carried out using Drytech Tanks.

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.
