Switzerland's first cellar made of wood
26.11.2020
Timbatec has been committed to wood construction for over 20 years. Our vision is to build entire cities entirely from wood. In Thun, Switzerland's first apartment building with a basement made of wood is currently under construction. We invite you to the virtual construction site tour on 04 December 2020 at 16.00.
The construction industry has an obligation and must significantly reduce its CO₂ emissions in order to comply with the Paris Climate Agreement. emissions significantly in order to comply with the Paris climate agreement. This can only be done by doing away with steel and concrete in building construction. Timbatec is happy to accept this gladly accepts this challenge. Since 2014, we have consistently avoided the use of concrete in concrete for floor slabs. Instead, we use dry-bonded fill. The next logical step is to do without concrete in basements and floor slabs. Today it is Today, it's a reality: We are building the first basement made entirely of wood.
The basement holds a lot

steel. Cement production alone is responsible for 5-8% of global CO₂ emissions.
One cubic meter of reinforced concrete causes around 500 kg of CO₂ emissions. The situation is quite different with wood: The naturally renewable building material
requires only solar energy and water. Each cubic meter of wood stores around one ton of CO₂ over the entire life cycle of the building. In the case of the superstructure
"Krokodil" in Winterthur, 6,418 tons of CO₂ are stored in the wood used. Approximately the
same amount was emitted during the production of the concrete for the basement floors.
Is that really necessary? Timbatec thinks so: No!
First basement made of wood for multi-family house in Thun
Product development has always been part of

pioneers in timber construction. This makes us part of and a driving force behind the success story

two-component polyurethane casting resin without pressure. The same
construction was chosen for the floor slab.

Research project
"DeepWood "
In the case of the multi-family house in Thun, it is not just the wooden basement that is an innovation.
is an innovation. The building is also the Living Lab of a research project
in the field of digital planning and BIM (Building Information Modeling). The research project "DeepWood",
together with the Lucerne University of Applied Sciences and Arts and the Bern University of Applied Sciences AHB in Biel, is developing the
basis for simultaneous and team-oriented collaboration. Planned
the building in Thun was designed with the 3DX platform from Dassault Systèmes using
CATIA. The initial findings show the strengths of the integrated
project space: There are no interface problems to solve. So that the
new approach can establish itself in timber construction, it needs well-developed
processes, routines, and templates - from planning and collaboration to automatic plan
automatic plan output and machine control.
