Waterproofing of the artificial pond

by
Playground in Basel Zoo

Drytech realised the waterproofing of the artificial pond of the Lange Erlen wildlife park in Basel with the Drytech Tank, built as part of the extension of the historical city zoo.

The construction of this zoo on the Wiese river in Kleinbasel dates back to 1871 and is still very popular with young Basel children every day.

The wildlife park allows children to get to know the animals within the protected habitat of an adventure farm.

The Drytech intervention is part of the facelift completed in 2018, which increased the surface area of the park by 3,000 m2, with new paths and a modern playground, inside which the artificial pond with the Drytech Tank waterproofing structure was built.

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.

Waterproofing the dock of a restaurant

by
The Fischer Stube restaurant in Lauerz emerges from the waters of the lake of the same name thanks to a waterproof Drytech white tub structure.

Waterproofing the dock of a restaurant on Lake Lauerz puts the Drytech Tank structure in direct contact with water.

The Seerestaurant Fischerstube in Lauerz/SZ is only 1.3 metres above the water level of Lake Lauerz.

On the outside, the slab of the dock is a large terrace housing the outdoor tables.

The interior of the restaurant welcomes guests with a harmonious mix of materials and a special ceiling installation: a wave-like architectural soundproofing that reproduces ripples.

An oval niche is set in the centre of the ceiling structure for effective indirect lighting.

In addition to the White Tank, Drytech applied DRYpox waterproof coating to the floor and walls of the entire basement.

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.

Waterproofing the basement

Aerial view of the Swiss-Life park district of Massagno

Waterproofing the basement of the Swiss Life park district, designed by Remo Leuzinger Architecture Studio with an important urban planning role.

The Swiss Life housing complex forms an archipelago that defines and enhances the view onto Via Lepori, consolidating the character of the urban axis of the artery and, at the same time, opens pedestrian passages that make an important part of the park accessible to the public.

The three articulated volumes of different heights integrate with the original valuable trees, proposing an image of buildings in the park. The irregular pentagonal plan of the main bodies overcomes the rigor of right angles, giving organicity to the volumes and fluidity to the orientation of the facades.

Each unit corresponds to a “Hortus conclusus”. Built with woven chestnut slat panels and galvanized iron wire, these nest-gardens reproduce the quiet and intimacy of a cloister, inside the park-neighborhood Swiss Life.

The heated outdoor pool at the Gstaad Sports Centre, built with the waterproof structure Drytech White Tank

Drytech realised the waterproofing of the new outdoor pool with whirlpool, the indoor pool and the SPA facilities of the renovated Gstaad Sports Centre.

A total of Chf 23 million was allocated for the renovation and extension of the sports centre, which also includes a 5-lane curling hall and a restaurant.

The building’s entire shell was reconstructed, and the roof and façades were renovated. In addition, the heat recovery, indoor pool ventilation and heating were renewed.

The waterproofing of cellar and walls in contact with the ground

by
Designed with the expressive power of a sculpture, the Chienbergreben private house in Gelterkinden follows the slope of the land, on the border between the town and the agricultural area.

The waterproofing of the cellar and the walls in contact with the ground was realised with the Drytech Tank waterproof concrete structure, in perfect coherence with the villa’s architecture.

Designed with the expressive power of a sculpture, the Chienbergreben private house in Gelterkinden follows the slope of the land, on the border between the town and the agricultural area.

The underground structures were built with the Drytech Tank System, which made them impermeable to both groundwater and slope water.

The adoption of the Drytech System, which provides for a single waterproof concrete structure, has allowed the project to respect the figure that defines it architecturally even in the underground part.

The entire structure of the building is in fact made of exposed concrete with disposable horizontal formwork: inside as well as outside.

Waterproofing of the communal car park

by
The dialects connecting the three buildings of the Baden Ruetihof residential complex

The waterproofing of the communal car park of a residential complex was realised with a Drytech Tank designed according to the different loads insisting on the slab, at the buildings or green areas.

The movement joints placed in correspondence with the load changes to avoid cracks were sealed with special DRYset waterstop tapes, injected with DRYflex expanding resin, which made the justs themselves waterproof for the entire thickness of the underground structure.

The three buildings that make up the residential complex crown the communal garden, which also houses play areas and green spaces. The arrangement of the three bodies allows each residential unit to have a view and independence that guarantee absolute privacy.

Thanks to the southern orientation of the living spaces, the lounge areas and the elegant loggias and terraces guarantee optimal exposure to the sun.

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.

Waterproofing the underground level

With the Residenza Bella, Locarno has a new landmark that characterizes one of the main entrances to the city.

With the Residenza Bella Locarno has a new landmark that characterizes one of the main entrances to the city.

The facades punctuated by the grid of windows, the entrances created in the corners cut at the base, the suggestive stone of the facades which interacts vibrantly with the solar arch, the dynamic and surprising shape of the profile: everything contributes to the powerful originality of this residential and commercial building, designed by architects Filippo Floriani and Marco Strozzi.

But only by reaching the south side does one discover that it has an extra façade.
In fact, part of the roof is actually a series of semi-covered terraces interspersed with green pools. The tops of the plants emerge from the profile of the pitch, giving organicity to the structure.

Designed around the needs of those who live there, Residenza Bella of Locarno relies on careful construction, the choice of materials and the advantages of home automation for excellent energy performance, which also allows the management costs of the individual apartments to be contained.

The parking spaces are equipped with charging stations for latest generation electric cars and the Drytech Tank underground structure also guarantees impermeability to radon, for an architecture that manages to combine beauty, character and living well-being.
