Projects

For the A12 Velperbroek interchange project, we delivered a 3D-printed slope stair to provide access to a service path. Due to a noise barrier, the control cabinet for the signal gantry was not accessible from the main carriageway. Thanks to the stair and the service path, maintenance is now simple and safe again.

At a dike house in Heinenoord, we delivered a fully customized 3D‑printed slope stairs, installed against a newly constructed concrete retaining wall. The combination of printed concrete with a hardwood frame creates a high‑quality, characterful appearance that blends seamlessly into the dike landscape. For the contractor, this is already the second 3D‑printed slope stairway they have chosen to use — a clear confirmation of their confidence in this efficient and sustainable solution.

During the busy summer months of 2025, Heijmans Infra carried out major maintenance works on the Buitenveldertbaan runway at Schiphol Airport. An intensive operation, especially right in the peak season of air traffic. A tightly coordinated schedule and close collaboration between all parties involved were therefore essential. In addition, sustainability played a central role. Efficiency and sustainability were key reasons for Heijmans to opt for 3D-printed slope stairs in this project.

For the construction of the new bus transferium on the Hoge Maasdijk in Andel, the municipality of Altena chose a 3D-printed slopestairs. The stairs connect the bus stop on top of the dike with the transferium, providing direct access to the site for travelers.

In the vibrant core of Amsterdam, where urban life and nature seamlessly merge, a groundbreaking slope stair has been installed—effortlessly bridging height differences while exemplifying the harmony of smart design and sustainability.

A 3D printed slope stair is the eye-catcher of the Netherlands' largest urban beach in Hoorn – completed in a record time of just three weeks.

At the Weidepad in Linschoten, a unique 3D-printed free-standing staircase has recently been installed at the fish passage.

Several new innovations were applied during the project. A 3D printed slope stair was of course indispensable in this regard.

The slopestair is not only a practical addition for access, but is also a visual element that blends in with the natural environment. This shows the power of cooperation between innovative technology and respect for nature.

As the first municipality in Limburg, a 3D printed slope stair has been installed in Stein municipality in the outlying area Steenwegstraat.

The new pumping station is a fine example of what cooperation can achieve. By combining innovative techniques such as talus stairs with local knowledge and craftsmanship, a sustainable solution has been realized that is ready for the future.

As part of the project ‘’Realisatie ontwikkeling haven Yerseke’’, two unique 3D printed slope stairs have been realized.

Commissioned by Waterschap Hollandse Delta, GKB Machines B.V. has installed a slope stair at the pumping station on the Ringdijk in Zwijndrecht.

In the Frisian landscape, near Bitgum, an innovative 3D-printed slope stair has been realized that combines functionality and sustainability.

Three concrete printed slope stairs have been printed layer by layer for the project ‘Landscapes Theemswegtracé’. Commissioned by the Port of Rotterdam Authority N.V.

At the Ouderkerkerlaan in Amstelveen, four 3D-printed concrete slope stairs have been installed. We produced these stairs, using an innovative production process that creates many hollow spaces. This has resulted in reduced CO2 emissions.
