Basements made of wood

Pour un projet pilote, la sollicitation du bois par l'humidité dans le cadre de la physique du bâtiment est étudiée et les détails de construction, le monitoring de l'humidité et l'assurance qualité sont développés.



The first wooden cellar in Switzerland has been built in Thun. The project was able to benefit from insights into waterproofing technology gained from the construction of flat roofs and ponds. Before cellars can be mass-produced using wood, there are a number of questions that first need to be answered. BFH researchers are accompanying the pilot project to examine and document the concept and to modify the system based on their observations. A number of the research partners are planning to found a startup, which will launch operations in 2023.

Course of action

The analyses performed in the context of the pilot project are supplying key parameters needed for a numerical representation of the physical processes involved in construction. This provides a scientific basis for optimising the system and extending the warranty period. Laboratory and field tests are still needed to determine the static behaviour of the various materials in relation to each other. This information will allow a startup to be launched on the market as a systems manufacturer of basements made of wood.

Looking ahead

The choice of construction method and the application of waterproofing help prevent any penetration of moisture into the wooden components. Through the combined experience of the business partners and the BFH researchers, the system basements in wood will be market-ready with a customary system guarantee for prefabricated basements.
