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.

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.

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.

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.
