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.

Any building type

We specialize in demolitions of concrete, reinforced concrete, brick, and mixed structures of any scale. We also carry out demolitions of hard-to-access structures.

Recycling of building materials

We have mobile crushing equipment, which we transport to the site to process masonry or concrete into recycled material for further use.

Eco-friendly disposal of hazardous materials

We can decontaminate construction and demolition waste contaminated with hydrocarbons at our bioremediation sites.

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.
