Czech Republic: A New Heart Beats in Brno Thanks to Soletanche Polska!
Soletanche Polska is carrying out the foundation works for the future Dornych real estate complex in Brno, Czech Republic — a project set to become the city’s new urban hub. In a dense urban environment, our teams are implementing a wide range of foundation techniques, including diaphragm walls, piles, anchors, struts, and micropiles.
An emblematic project in the heart of Moravia
Ahoj! Welcome to Brno, Czech Republic. This is where one of the region’s most ambitious urban development projects is taking shape: the Dornych project, designed to become the city’s new beating heart. The large-scale construction is taking place on the site of the former Prior department store. For the client Crestyl, Soletanche Polska is performing the foundation works on behalf of GEMO a.s., a major player in the national construction market.
An ambitious architectural vision
The complex will comprise six modern buildings, with a total usable area of over 25,000 m².
It will include:
• a hotel;
• high-end residential apartments;
• restaurants and leisure spaces;
• shops and services;
• modern office spaces.
All buildings will be connected by a shared underground level, housing parking areas and storage zones.
Large-scale foundations and precision engineering
The foundation works carried out by Soletanche Polska include:
- 485 linear meters of diaphragm walls, divided into 75 panels;
- 340 ground anchors, each approximately 25 meters long;
- 600 CFA piles, drilled from the bottom of the excavation;
- micropile walls supporting the adjacent pedestrian bridge;
- corner struts reinforcing the stability of the walls.
A complex site at the heart of a strategic urban hub
The Dornych project is located in a dense urban environment, in close proximity to Brno’s central railway station, major roadways, an existing steel pedestrian bridge, and an underground utility collector.
This configuration requires meticulous logistics. For example, the nearby pedestrian bridge demanded the installation of a micropile retaining wall and shorter diaphragm walls (3 m instead of 8 m) to ensure its stability. A similar solution was implemented around the underground collector.
Additional challenges include the discovery of 18th-century remains during excavation and the simultaneous demolition of the old Prior building. The entire operation requires surgical coordination between teams, heavy machinery, and numerous constraints within a confined space — just 15 to 20 meters from existing infrastructure.
A Polish footprint in Central Europe
Hubert Tomczak, Managing Director of Soletanche Polska, states:
“Dornych is an exciting new project we are carrying out outside Poland. Our teams are now active in Lithuania, Slovakia, and here in the Czech Republic, where we are managing two major construction sites. This strengthens our regional presence while consolidating our position as a European leader in the geotechnical sector.”
