The row Capacity cbm/h is based on 100-200 mm depth and a standard concrete 30 MPa.
Hydrodemolition robots are simply the better, safer, more dependable, and more ecologically responsible choice when it comes to selectively removing concrete components from an existing structure.
The hydrodemolition robots’ automation makes it simple for the operator to carry out both selective and non-selective removals. Whichever choice you select, the high-pressure water jet technology will produce a rough surface that is ideal for bonding new concrete without causing any microcracks or causing damage to the surrounding structure.
OVERVIEW
Protective Coating Systems (PCS) supplies concrete maintenance, protective coatings, non-skid flooring and concrete repair services to mining, industrial and commercial clients.
PCS approached BlastOne to provide a solution for a challenging application in Bunbury, Western Australia. This involved the need to expose post-tensioning cables in concrete without damaging the cables. In order to inspect or repair post-tensioning cables, they need to be exposed, which can be a difficult and delicate process.
SOLUTION
BlastOne recommended the use of a Conjet 557 concrete demolition robot in conjunction with a 1400 bar (20,000 psi) NLB Water Jet Pump which enabled the concrete to be removed to a controlled depth of 150mm around the cables.
The Conjet robot is operated remotely, which means that the operators can be positioned safely away from the work area, reducing the risk of injury or exposure to dust and debris.
The alternatives to using the robot would have been to either use percussion tools – with the likelihood of damaging the cables, or to use a hand-held water jet lance – putting the operator and environment at risk from the high-pressure water jet and flying debris.
RESULTS
PCS had designated a 3-month period to complete their scope of works onsite, The results achieved far exceeded their schedule with all works being complete in just 3 and a half weeks.
The project was carried out safely and effectively in a fraction of the time.
BlastOne was also able to provide a complete solution as the customers employees were experienced in the UHP sector, but were not fully qualified. BlastOne collaborated with a well-respected company that were able to offer onsite training and supervision, which by the end of the project would see their employees competent UHP Operators.
CONCLUSION
In conclusion, BlastOne’s Conjet Robot was the ideal solution for the customer’s building extension project, which presented several unique challenges. With the combination of product training, robotic equipment and BlastOne’s expertise and support, the project was completed quickly and efficiently, exceeding the customer’s expectations.

As a rule of thumb we have found that the optimal water pressure is 3.5 times the compressive strength of the concrete. Once this optimal pressure has been set then productivity can be increased by increasing the volume of water.
We would be glad to assist you by providing a suitably sized pump for rental or purchase.

We recommend the use of a powerful vacuum system such as our Vacuload 8, along with an interceptor to remove the debris.
Yes, the robots can be used for surface preparation of both concrete and steel at up to 2800 bar (40,000 psi) when fitted with the appropriate rotor head.
