Concrete Removal

Project – Concrete removal on a major construction project 
Equipment Used – Bruno Mini 
Pipe diameter – 375mm 
The DrainJet Robotics system has 3x robots to suit the job at hand.  From large diameter pipework to major access issues, we have the solution.

The Problem 

Our client called us urgently requesting attendance after a separate contractor had accidentally flooded a main surface water sewer with concrete.  The pipework was roughly 15 metres deep and running underneath a tram line as well as a canal.  The project was extremely high-profile in a city centre meaning a discreet service was paramount. 

The Solution

The concrete within the pipe was foundation grade (C40) and blocking 100% of the pipework for 15 metres.  Access was in the centre of the an active site which posed major access constraints.  Normally, this diameter would be best suited to Big Bruno, however, the access meant that the larger, heavier robot could not be inserted into the pipe safely.  

The Outcome

Bruno Mini offered the solution.  The smaller and lighter robot meant inserting the robot was not an issue.  With the same capabilities in all our robots, we were able to remove an average of 1 metre per shift, restoring full flow to the system and getting the clients project back on track.  

Average milling robots would remove a maximum of 100mm per shift given the volume and strength of the concrete.
