One of our main areas of focus is the production of CE-certified building materials from building construction waste. We offer high-quality concrete and brick recycling products in a wide range of grain sizes. We supply crushed stone, sand and gravel to construction companies, mixing plants and private customers throughout Vienna, Lower Austria and Burgenland. 

At our Vienna site, we take care of the temporary storage and disposal of waste. The facility in Seybelgasse serves as a collection point for mineral construction waste, excavated material, construction and demolition wood, as well as construction site waste. Our mobile crushing plants and equipment are the right choice when construction waste needs to be processed directly on site. And our roof substrates not only make roofs greener, but also our world.

Processing of construction waste

Professional recycling of building materials

Our versatile plant in Himberg offers the possibility of processing various types of construction waste and using it to manufacture high-quality products.

Legal regulations as well as strict internal and external controls enable the production of CE-certified building materials. By processing mineral materials in this way, we contribute to the conservation of natural resources as well as the sustainable use of raw materials.

In our processing plants, mineral construction waste is recycled just as professionally as brick and concrete demolition waste.

Processing of construction waste

Incoming inspection guarantees product purity

For the processing and reuse of construction waste, the delivered material is subject to a visual and documented incoming inspection. This enables us to ensure that only pollutant-free and uncontaminated raw material is sent for processing. Demolition material containing harmful and disruptive substances as well as excavated soil cannot be accepted at the Himberg site.

The degree of contamination of the delivered material is determined based on the proportion of foreign substances such as mortar, wood or plaster. Materials such as insulation material, plaster, Heraklit, soil, Ytong, etc. cannot be further processed at the Himberg site. We pass on sorted and non-recyclable materials for proper disposal. After the incoming inspection, special screening and crushing plants prepare the materials.

Processing of construction waste

Production of high-quality brick sand and brick chippings

In a stationary plant, brick demolition waste is processed using state-of-the-art technology. The materials are screened by machine, sorted by hand, washed and crushed. 

Unwanted foreign materials such as wood, plaster or metals are separated from the material flow and sent for separate recycling. After the raw material has been crushed, it is finally screened into the respective grain sizes.

The other plants process concrete demolition waste and mineral building construction residues. This is followed by temporary storage until the materials are reintroduced into the cycle. The necessary separation of unsuitable building materials is carried out mechanically using state-of-the-art screening, air separation and magnetic separation equipment. As a final step, our employees remove any remaining unsuitable building materials by hand sorting. 

Recycled products

Wide range of applications

Our recycling plant produces high-quality concrete and brick recycling products in a wide range of grain sizes. Quality assurance is carried out through ongoing internal and external checks. This ensures product quality and compliance with all legal requirements.

Our products are used in a wide variety of areas: for example, as lower or upper base courses in road construction, as drainage or trench filling material, for backfilling, in landscaping and gardening, or in green roofing. But see for yourself the wide range of possible applications.

Roof substrates

The world needs green roofs

Extensive green roofs provide ecological compensation areas and have a variety of positive effects on the climate and the environment

In addition to gaining green space and creating valuable habitats for animals and plants, green roofs also serve as sustainable storage for rainwater. Green roofs help cool the surrounding area, improve the microclimate and reduce particulate matter pollution.

Every roof has its own requirements and needs individual preparation and maintenance. There are a variety of technical options and systems for greening roofs. To choose one of our products, it is best to contact our partner companies, who will be happy to consult you on the subject of green roofs. As a proven supplier to numerous specialist companies, we are happy to manufacture and supply individually tailored products.
