A robot that lays walls,
right on site.
Europe's construction sites are short two million workers by 2030. ERLEtek builds a mobile robot that prints walls on site today.
Construction can't hire its way out of this.
Europe's construction sector needs roughly two million more workers by 2030, driven by renovation targets, climate-adaptation projects, and a workforce that keeps getting older. Demand is rising faster than the industry can staff it.
The work hit hardest is often the least skilled and most physically wearing: pouring long, repetitive runs of concrete wall, by hand, on uneven ground, in the rain. It's the kind of job that stays open even when the pay is decent, because fewer people want to do it.
Mobile. Modular. Built for real ground.
ERLEtek's printer travels to the job site instead of the job site coming to a factory. It sets up next to the wall it needs to build, reads the terrain underneath it, and prints in place using a vibration-based process that works with both concrete and clay-based mixes.
A human crew still runs the site. The robot takes the part of the job that's long, straight or curved, and repetitive, so skilled workers spend their time on the parts that need judgment.
| Wall height | Up to 2 m |
| Wall thickness | 10 – 40 cm |
| Pilot run length | ~100 m, repetitive wall |
| Materials | Agnostic |
| Deployment | Q2/Q3 2027 |
| Business model | OEM — ERLEtek leases the robot, the customer's own crew operates it |
Where we are.
Technology developed and first prototypes tested at DTU, Copenhagen.
Accepted into the program, giving access to DTU's research network and ESA's technical resources.
Roskilde load test: validating a 3D-printed floodwall's load-bearing capacity, the technical proof our partners need before construction starts.
First project: a 100 m coastal floodwall protecting harbour-front homes from wave overtopping, built with our contractor partners.
Target for a commercial-ready, deployable robot, following pilots through 2027.
