Waterproofing of the Allianz Isozaki skyscraper

The Isozaki Tower in the CityLife district, inspired by Costantin Brancusi's endless column, has become one of the symbols of the city of Milan.

Drytech designed the waterproofing of all structures below the design water table of the Allianz Isozaki skyscraper in Milan.

Therefore, the fireproof tanks, the plant tunnels, the polyphores and the basements were built with the Drytech Tank System.

The Isozaki Tower, inspired by Constantin Brancusi’s endless column, has become one of the symbols of the city. Designed by the Japanese architect Arada Isozaki together with the Italian architect Andrea Maffei, the skyscraper is the headquarters of Allianz in Italy.

The building, which can accommodate up to 3,800 people, is the tallest skyscraper in Italy by number of floors (50) and according to the highest occupied floor criterion (with its 207 m).

Waterproofing a logistics hub

Waterproofing a logistics hub realised with the Drytech Tank structure: the Service Centre (DLC) of Walter Meier (Climate Switzerland) AG is a 12,000 square metre storage area that serves efficient and ecologically optimised logistics.

The company is integrating energy efficiency into the new building: the DLC is built according to the Minergie standard and the building services are equipped with state-of-the-art technology.

For example, with the use of a large PICO heat pump for heating and cooling.
A photovoltaic system with 4,200 panels is also installed on the 7,200 square metre roof.

Waterproofing of the skyscrapers

The theory of skyscrapers in Milan's Porta Nuova district, the basement of which was built with a 43,730 m² Drytech White Tank waterproof structure.

The waterproofing of the skyscrapers in Milan’s Porta Nuova district was carried out with 43,730 m² of Drytech Tank.

The masterplan of Milano Porta Nuova was signed by the Kohn Pedersen Fox studio of London, while the executive plan is the work of the Arquitectonica IC of Miami and m²P Associati of Milan, for the commissioning of Hines Italia and Galotti SpA.

3,000 m² are destined for the Municipality of Milan to make it a cultural center. The four underground levels, made with the Drytech Tank waterproofing system, house parking spaces for 2,000 cars.

Drytech has built 43,730 m² of waterproof underground structures with the White Tank System, collaborating with the designers of Arup Italia in Milan and coordinating with the CMB company for the preparatory activities for waterproofing which, being parallel to those of the construction site, are in fact been removed from the work calendar.

Gärtnerei, Bärau

The greenhouses of the Bärau garden centre.

Schon vor über zweihundert Jahren entstand in Bärau bei Langnau das erste Gebäude.

Heute ist das kleine Dorf die grösste Institution des Kantons Bern im Bereich «Wohnen und Leben mit Beeinträchtigung»: Es leben dort betagte und pflegebedürftige Menschen in Eintracht mit Erwachsenen, welche an psychischer, sozialer oder geistiger Behinderung leiden.

Weshalb sich auf dem Areal zahlreiche Betriebe der Sparten Gastronomie, Handwerk, Gärtnerei, Land- und Hauswirtschaft befinden.

Letztlich dienen sterben hier erwirtschafteten Rohprodukte teilweise der Selbstversorgung des «Resorts Lebensart».

Mithin entstand ein reiner Zweckbau, wenngleich man bewusst auf Blech bei der Auskleidung der Halle, from der Gebäudekomplex eine Wertigkeit verzichtet erhalten sollte: Mittels Holzbauweise gleichzeitig Gesamtstabilität und Erdbebenserticherutheit sow.

Die Fassade musste ästhetisch in ökologisch unbehandeltem Struktur-Holz – hier Weisstanne aus dem Emmental – etwas hergeben!

Im Erd- und Untergeschoss befinden sich vor allem Produktionsflächen plus Lager, im Untergeschoss zusätzliche Parkplätze.

Waterproofing an 8-metre deep underground warehouse of Geissmann Papier in Dottikon, realised with the Drytech Tank structure.

Architects Xaver Meyer of Villmergen designed a large, purely functional three-storey building, in which the structural grid of the building had to be adapted from the outset to the logistics required inside.

The basement warehouse is used for the storage of heavy plastic rolls for the production of packaging material.

A ventilation system with mechanical exchange was installed inside the building to recover heat from the exhaust air, also in the existing factory.

The floors are impressive in terms of reinforcement, guaranteeing a payload of 2.5 tonnes per square metre on the ground floor and 1.5 tonnes per square metre on the first floor for the equally heavy rolls of plastic delivered and stored on pallets.

Drytech waterproofed the new production hall

Drytech waterproofed the new production hall of Pilatus, the Swiss business aircraft manufacturer.

The new hall, 196 metres long and 170 metres wide, with a usable area of 17,200 square metres, is impressive.

The wooden construction covers an area of 52 x 192 metres without supports. The revolutionary beech trusses allow the total loads to be transferred to the foundations through the six main beams (90 tonnes per beam) and the outer walls.

The main beams consist of solid glued trusses (16 tonnes each) made of glued spruce, supplemented by steel beams.



The foundations are made of waterproof Drytech concrete.

Waterproofing of the car lift pit

Building in Niederrohrdorf, with waterproof underground Drytech White Tank

Drytech carried out the waterproofing of the car lift pit and the associated underground car park of an elegant building in a residential area.

For reasons of space, access to the underground car park built directly underneath the residential building could not be via a conventional ramp. For this reason, architect Meinrad Müller designed the car lift, which, like the entire basement, was built with the waterproof concrete structure of the Drytech Tank.

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 the artificial pond

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 the dock of a restaurant

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.
