Gravel placement and removal, filling, greening and cleaning: all part of our daily business. We remove all liquid and dry materials by suction from any location, and we even transport lean or permeable concrete at lightning speed. Whether you need a complete structure starting with the roof cladding or a green roof, we will advise you on every aspect. We will help you choose the substrate that suits you best and will deal with transporting it quickly and carefully onto your roof. Which type of greening do you want: extensive or intensive? You can also rely on us here. Maintenance of your roof is one of our strengths! We make sure that your greenery grows correctly and stays where it is supposed to be.



We remove a wide variety of wet and dry materials from any location with our special vehicles.

Pressure blowing

Pressure-blowing of gravel, substrates, crushed stone, cavity filling, backfills, lean, permeable or expanded concrete.

Green roofs

We will gladly advise you on extensive green roofs and transport the optimal substrate onto the roof for you.

Our sites provide services throughout Switzerland and beyond its borders.
