Waterproofing of the communal car park

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.

The underground garage of the SPZ complex made with the waterproof structure Drytech White Tank

Drytech realised the waterproofing of the underground car park of the Schweizer Paraplegiker-Stiftung in Nottwil, on the banks of Lake Sempach.



Due to the presence of a significant water table, the large underground car park and all underground rooms were constructed with Drytech Tank waterproofing.

Car park D has 242 parking spaces on two floors, 31 of which are specially designed for wheelchair users.

The waterproofing of the underground structures of the Tissot Arena, starting with the underground car park, was realised with the Drytech Tank system.

The multifunctional sports and cultural complex is unique in Switzerland in that it combines a football stadium, an ice hockey stadium, an ice rink, a football training ground and a curling hall under the same roof.



In mid-2016, three more outdoor training grounds were completed to complete the overall stadium facilities. Inside, there are also large commercial areas, cinemas and a large multi-storey car park built with the waterproof concrete structure of the Drytech Tank.



The flexibility of the rooms also allows the stadium to host cultural events of all kinds, from concerts to conferences, allowing the facility to be used every day of the week.



In addition, Energie-Service Biel operates the world’s largest stadium-integrated solar power plant on the roof of the Tissot Arena.

Abdichtung historischer Gebäude mit Steinmauern

The interior of the new headquarters of the Dand Habitat Foundation in Basel, renovated by Kräuchi Architects.

The waterproofing of historic buildings with stone walls and their integration with new waterproof concrete structures is an issue that Drytech Tank solves with effective, integrated solutions.

The Dand Habitat Foundation, which builds quality and affordable housing in Basel, purchased nine historic buildings in Kleinbasel to make them its headquarters.

Basel-based Kräuchi Architekten designed the renovation by combining the various buildings, with their different levels and floors, into a unified whole, under the supervision of the Basel Office for the Preservation of Historic Monuments.

Drytech first sealed the perimeter of the stone walls with a horizontal chemical barrier to prevent rising damp. It then built a waterproof concrete slab and sealed the joint with the stone walls with injections of DRYflex expanding resin, ensuring the total watertightness of the basement.
