Handl Commercial Construction, Haiming Tirol
2020
In the Austrian Tyrol, a 650-square-meter cross-laminated timber panel was constructed in just two days using TS3 technology. This sets a world record: it is the largest single piece of CLT.
The Project
Markus Handl Beteiligung GmbH is an Austrian family-owned company based in Tyrol. Given the company’s focus on its home region, it stands to reason that Handl GmbH would rely on wood, a natural building material, for the construction of this major new project.
For the new production building in Vorarlberg, Austria, the panel end faces were pretreated with TS3 special primer at the Binder CLT plant in Unternberg and immediately afterward fitted with sealing and segmentation strips. The 3.5-meter-wide panels, some weighing over five tons, were loaded just-in-time and transported directly to the construction site in Pians with an escort vehicle.
Construction Method
A temporary scaffold was erected for the installation. TS3 ensures a rigid connection between the individual 240 mm cross-laminated timber panels using patented casting technology with Henkel’s two-component polyurethane adhesive. The Spider column head reinforcement from Rothoblaas was installed above the columns in a 7 x 7-meter grid. X-Fix devices from Schilcher Trading & Engineering GmbH were used as assembly aids.
The Challenges
Until now, the TS3 joints were constructed in parallel. These were each laboriously sealed on the underside of the slab. In this project, an advanced joint design was implemented for the first time. This requires less casting resin and simplifies the process, as sealing on the underside is no longer necessary.

Today, he is driving timber construction forward with new developments such as TS3 technology, Scrimber, wooden basements and Timber Finance. He wants to enable a construction industry without steel and concrete. Read the interview here. (Interview in german)
Roof construction breaks records
Mikado, June 2021 - The Austrian retail company Handl has had a new gastro service hall built in Pians. The special feature is the huge wooden ceiling with an area of 650 m2. The roof was created through teamwork between industry and science.
