In Schandorf, a pioneering exhibition space was created using an innovative construction method: a resource-saving concrete shell was created using a inflatable tires erected, a process using basalt reinforcement that was implemented for the first time worldwide.

The development was carried out in cooperation with the Southern Burgenland Tourism Association, the TU Vienna, BOKU Vienna and Woschitz Engineering. The implementation was carried out by Porr Bau GmbH.

The special:

• Up to 30 % concrete savings
• Reusable formwork (Tire)
• Basalt instead of steel: Lightweight, non-rusting, high tensile strength
• Short construction time of only two months
• Less CO₂-Emissions, reduced material transport
• Modern construction monitoring by 3D scans & LIDAR

Construction in brief:

1. Concrete slab + tire on top
2. First concrete layer is poured flat
3. Tire is inflated, the hardened shell curves into a dome
4. A second layer of concrete provides the final stability

Degree of innovation:

• Technological: innovative shell statics & material combination
• Ecological: resource-saving, efficient, reusable
• Economic: new potential through EU taxonomy & CO₂ pricing

Funding & Partnerships:

• Supported by LE funding, FFG Austrian Research Promotion Agency & AWS Austria Business Service
• Close cooperation with TU Vienna, BOKU Vienna & Research Burgenland

Services: Planning, tendering and on-site construction supervision

Client: Municipality of Schandorf

Construction method: Prof. Kromoser
