Earthworks create the basis.
Earthworks comprise all construction measures that change the soil's position, form and storage qualities. They create the basis for projects in the fields of road construction, canal construction, dam construction, landfill, sealing, soil masking, landscaping, culvert construction, noise barriers and many more.
Embankments are typical earthworks. They are required for traffic routes such as canals, roads and railways, but also for barrages and landfills. Levelling and compacting large areas falls within the scope of earthwork activities, as does supplying sand, gravel or topsoil and disposing of soil.
As a subsidiary of PORR Umwelttechnik GmbH, Koller Transporte-Kies-Erdbau GmbH specialises in these earthworks. The company implements smaller construction projects such as temporary construction pit systems for single-family houses, and also large infrastructure projects for clients such as Hafen Wien or ÖBB.
