High Safety Risk
Workers spend hours on scaffolding at height, performing repetitive tasks under significant fall hazard conditions.
Automated Masonry
Joint Renovation
Useful Machines is developing an autonomous robotic system to renovate deteriorated mortar joints in brick facades.
Faster. Safer. Cheaper.
Mortar joint renovation remains a highly manual and work intensive process.
Millions of square meters of brick facades across Europe require regular maintenance, a process that is still almost entirely done by hand.
Slow & Labor-Intensive
Manual repointing is extremely time-consuming, creating project bottlenecks and driving up costs for building owners.
Inconsistent Quality
Quality varies significantly between workers, leading to uneven results and faster deterioration of repaired joints.
Skilled Labor Shortage
The construction sector faces a growing shortage of qualified craftspeople, making it harder to scale renovation projects.
Autonomous renovation,
floor by floor
Our robotic system navigates brick facades and autonomously removes, prepares, and refills mortar joints with consistent precision.
-
Automated joint detection: The system identifies and maps deteriorated joints using onboard sensing.
-
Robotic removal & preparation: Old mortar is extracted cleanly and uniformly, preparing each joint for refilling.
-
Precision mortar application: Fresh mortar is applied with consistent depth and profile along the full joint length.
-
Ground-based operation: The robot works on the facade while the operator stays safely on the ground.
Built for real construction environments
Our system is designed around the practical realities of renovation work on active building sites.
Safety First
No workers at height. The robot handles the dangerous facade work while the team operates from the ground.
Higher Throughput
Automated operation dramatically increases renovation speed, reducing project timelines and scaffolding rental costs.
Consistent Quality
Every joint is processed to the same specification. No variation from worker fatigue or differences in experience.
Scalable Operations
One team can supervise multiple robots simultaneously, enabling contractors to take on larger projects with fewer workers.
Full Documentation
The system logs every joint processed, providing complete coverage reports for building owners and quality verification.
From site to finish
in four steps
Our deployment process fits seamlessly into standard renovation project workflows.
-
Site Assessment
We assess the facade, joint conditions, and site access to plan the deployment.
-
System Setup
The robot is mounted and configured for the specific facade dimensions and mortar type.
-
Autonomous Work
The robot processes the facade row by row with continuous quality monitoring.
-
Handover & Report
A complete job report is delivered documenting every treated joint and total coverage area.
