Pile foundations for the new Moltke School
Düsseldorf, Germany / 2025
As the bearing capacity of the ground was insufficient, PORR Spezialtiefbau Düsseldorf manufactured 71 Atlas piles (46/56) with a length of 7.35 metres for the foundations of the new community primary school. The construction site is a prime example of PORR’s ‘Green and Lean’ sustainability strategy and has been certified as a ‘Sustainable Specialised Civil Engineering Construction Site’ by the German Sustainable Building Council.

A sustainable building site: Pile foundations for the new Moltke School in Dinslaken
The Moltke School, founded in 1876 and situated between Dinslaken and Oberhausen, sees itself as a small school on the outskirts of the city. As the main building, which dates from the 1960s, did not provide sufficient space, portable classrooms were used for lessons for a long time. This temporary arrangement is to be replaced by a modern, three-storey new building by 2026. The listed old building will be refurbished and used for open all-day childcare.
DGNB-certified as a “Sustainable Construction Site – Specialised Civil Engineering”
PORR Specialised Civil Engineering holds the DGNB Basic Certificate for “Sustainable Construction Site – Specialised Civil Engineering”. For the construction site in Dinslaken, only project-specific evidence was required – which the team fulfilled with an outstanding result. Furthermore, as with every specialised civil engineering project, the PORR team assessed potential environmental aspects as part of the Group-wide environmental management system. These include, amongst other things, the use and storage of hazardous substances, the prevention of noise, dust, vibrations and waste, the protection of soil and groundwater, and the protection of trees.
Atlas piles form part of PORR’s Greenpile® pile system.
The Atlas piles used for the foundations of the Moltke School represent a particularly sustainable method that meets the high standards of the certification system. As there is no excavated material due to the complete soil displacement, there is no need for transport or disposal. The slender pile geometry reduces the amount of concrete required, and the low-noise, vibration-free construction minimises disruption to local residents. Furthermore, the regional sourcing of ready-mixed concrete and reinforcement cages contributed to a particularly positive environmental footprint.
