A mobile robot for on-site wall construction

What it is
The machine is an easy-to-deploy mobile 3D-printing robot designed to support construction teams in building wall structures directly on site.What it builds
The first application is flood protection walls, where repetitive wall construction, labour intensity, and climate adaptation needs make automation especially valuable. Over time, the technology can support other low and repetitive wall structures in construction and infrastructure.How it is deployed
The machine is brought to site, set up close to the construction area, and used to print wall sections directly where they are needed. The goal is to make wall construction faster, more flexible, and less dependent on heavy manual work.What materials it uses
The machine uses vibration-based printing technology and is designed to work with different printable materials, including concrete and clay-based solutions.What stage it is at
ERLEtek is currently developing and testing the machine through demonstrations and pilot projects, with flood protection walls as the first focused use case.

Use cases

ERLEtek focuses on wall structures where construction is repetitive, labour-intensive, and where automation can support workers directly on site.- Flood protection walls- Retaining walls- Climate adaptation walls- Harbour and coastal test walls- Landscape architecture- Other repetitive low-wall structures

Why it matters for construction companies

Construction companies are asked to build faster, safer, and with fewer available workers. ERLEtek supports construction teams by automating repetitive wall-building tasks directly on site.- Less labour-intensive
Reduce the manual work needed for repetitive wall construction.- Faster execution
Support shorter project timelines by automating time-consuming building processes.- Improved safety
Limit worker exposure in challenging areas such as rivers, coastlines, harbours, and infrastructure sites.- Less formwork dependency
Print wall structures directly on site and reduce reliance on traditional formwork and manual wall building.- Better use of workers
Free skilled workers from repetitive tasks and move them toward higher-value work.nsive.
