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 a museum and its car park

by
Designed by the Ticino architect Ivano Gianola, the Lac is the new, iconic cultural center of Lugano, which hosts a large theatre, an art museum, exhibition halls, spaces for events and which creates a square in continuity with the city's urban planning , which  offers convenient underground parking on the lakefront.

Waterproofing a museum and its car park is a job of great responsibility, made even more delicate by the structure’s proximity to the lake.

Designed by the Ticino architect Ivano Gianola, the Lac is the new, iconic cultural center of Lugano, which hosts a large theatre, an art museum, exhibition halls, spaces for events and which creates a square in continuity with the city’s urban planning , which  offers convenient underground parking on the lakefront.

The complex integrates the façade of the historic Hotel Palace and develops around a large square which can in turn host shows and exhibitions.

The city also has 10,000 m² of pedestrian areas and a park behind the building.

Drytech designed and built the waterproofing of the underground structures of both bodies, for a total of 19,800 m² of Drytech Tank, built below the level of the lake.

The edges of the pool and the walkable areas are waterproofed with the continuous Drycoat, which adapts like a second skin to the surface.

SBB CFS FFS train station, Lugano

by
The large canopy protecting the underground atrium connecting Lugano's railway station to the city.

An atrium that creates a new connection between the Lugano railway station and the urban fabric: a real portal that connects arriving and departing travelers 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.
