Wood instead of concrete. Very simple.



In Frenkendorf in Basel-Land, the first four-storey column-panel construction made of wood is being built. With the "Fasanenhof" apartment building with 15 apartments, TS3 technology proves its potential. The people involved are enthusiastic.

The construction industry is facing a radical change: timber construction is conquering large buildings with a new technology. TS3 makes large areas of wood possible. This means that wood can replace traditional reinforced concrete in many projects - this is good for the climate. The technology is the result of 10 years of research and development by Timbatec together with the Bern University of Applied Sciences and the ETH Zurich. With the four-story apartment building in Frenkendorf, the proof of concept is more than fulfilled.


The assembly of the CLT panels on the columns is easy. The wood remains visible on the supports and the ceilings.

During a site tour with invited guests, the architect and the project manager share their experiences with the new technology. Investors are looking for investment properties with the best possible profitability. Convincing the client of the timber construction option often takes time and energy, says architect Andreas Scherer. During the persuasion phase, we have to continue planning the construction project in different material variants. Here TS3 plays into our hands. With TS3 we can plan in concrete and build in wood. Planning with the three-dimensional load-bearing cross laminated timber panels is similar to projects in reinforced concrete.

Timber is the better solution 

We are an office that is comprehensively committed to sustainability, emphasizes Scherer from Scherer Architekten AG. It makes absolute sense to replace energy-intensive materials with less energy-intensive ones. That is why we try to replace steel and concrete with wooden constructions wherever possible and reasonable. At the "Fasanenhof" we were able to save almost 600 tons of CO₂ by switching from concrete to wood.

This does not affect us much with the TS3 joint. We can do our normal procedures, explains Benjamin Kaiser, project manager at Stamm AG. Thanks to the meticulous planning and prefabricated components, we are able to erect the building with 15 apartments within only three weeks. With construction projects involving a lot of steel, brick and concrete, this takes much longer. Often these materials are still being planned and decided on the construction site. This massively disrupts the construction process. With wooden buildings it is different. Technologies like TS3 and construction processes where the timber construction determines the accuracy are worth their weight in gold for us, Kaiser explains. 


View into the stairwell core: In large construction projects, master builders often first concrete the stairwell core. Carpenters then assemble the prefabricated wooden components. Timbatec has reversed this sequence: the wooden structure is erected, then the liquid concrete is poured in. 

The Timber Structures 3.0 technology, or TS3 for short, is a process that can generate large areas from wood - without the crossbeams that have been common up to now. These large surfaces can replace reinforced concrete in most areas. TS3 connects wooden components at the front. For decades, this was considered impossible. The solution is a two-component polyurethane casting resin. This resin connects the wooden elements with each other on the front side. This enables column-panel constructions that were previously only possible in reinforced concrete projects. This means that timber construction is now in its third generation - a quantum leap that is causing the construction industry to rethink.  


The CLT plates are pre-treated in the manufacturing plant. A sealing strip (white) is mounted on the front side to prevent the casting resin from escaping from the joint. To ensure an optimal joint sealing, the joint is divided into segments (black strips).

The implementation of the TS3 technology on the construction site has been continuously optimized, so that today we are faster and cheaper than in the first projects. An important innovation is the V-shaped joint. The joint is hardly visible on the underside of the ceiling and the consumption of casting resin is significantly lower. An apartment can be cast in just one hour. At the current cold temperatures, the casting resin and the interior rooms are heated.
