In the field of earthworks, we engage in construction work in which the ground is changed – in its position, shape and storage properties. Whether it’s a pipeline trench, a dam or an excavation pit: Earthworks are needed for the construction of transport routes, landfills and dams in particular. Our services not only include the levelling and compaction of large areas, we also supply gravel, sand or topsoil and take care of soil mass disposal.
From stabilising excavation pits to large infrastructure projects
As a PORR subsidiary, Koller Transporte-Kies-Erdbau GmbH specialises in earthworks. The company carries out smaller construction projects like securing excavation pits for single-family homes as well as large infrastructure projects for clients such as the Port of Vienna or ÖBB, the Austrian Federal Railways.
