We operate on the front line.
A close-meshed network of utility lines makes life as we know it possible in the first place. Power, gas, water, sewer, telecommunications or district heating lines – PORR is not only a specialist for excavation but also laying work. Such tasks require special competences for utility lines are not just laid on greenfield but often in inner-city areas with elevated traffic volumes and restricted space. A large number of other installations such as existing lines or foundations presents further challenges. Thus, lines sometimes are laid at depths of up to 10m which requires special safety measures to secure open trenches and ditches.
