Safe demolitions and dismantling work
We handle demolitions of industrial and agricultural complexes, factories, bridges, chimneys, and other buildings. Depending on the specific structure, we select the most suitable technological process, obtain demolition permits, process and remove all debris, and prepare the site for new use.
We carry out demolition work and land adjustments with respect for environmental protection
We also ensure the prevention of all potential environmental risks. Hazardous materials such as asbestos or various chemicals are handled in a way that prevents their spread to the surrounding area.

Mechanical demolition where space conditions allow
For mechanical demolition work, we use hydraulic demolition shears and breakers mounted on heavy construction machinery. If space permits, this technology can be applied to all of the following types of structures:
- Reinforced concrete, concrete, brick, and mixed structures, including foundations
- Steel structures
- High-rise buildings and chimneys
- Bridge structures
Gradual demolition using small machinery
If heavy demolition equipment cannot be used and manual dismantling is not feasible due to time constraints, we proceed with gradual demolition of the structure using small machinery (e.g., mini excavators). This method is suitable for densely built-up areas, inaccessible structures, or high-rise buildings. It is primarily used for:
- Demolition of parts of buildings
- Interior dismantling work
- Demolition of high-rise structures
- Demolition of steel structures
Demolition of structures below the waterline
Our machinery is equipped with a special auxiliary circuit that allows the use of hydraulic breakers underwater. This is utilized, for example, in the demolition of bridge piers in watercourses.
