Hydrodemolition techniques including manual, machine mounted, robotic systems and Cold Cutting.
Silver Raven is well known for innovation and develop and fabricate their own systems and jigs to suit specific projects. Silver Raven also invest in the latest developments in technology and machinery and provide both manual or automated demolition services, depending on the application and access requirements.
Silver Raven is a firm believer in educating the marketplace on the latest technologies and methodologies to give clients an understanding of what is achievable with Ultra High Pressure (UHP) techniques.
Despite the complex times we are living in, the Silver Raven team decided to host a demonstration day at our Marrickville facility for a group of clients.
Led by the founder and CEO Michael Flannagan and Hydro Manager, Jake Kennedy, the objective was to showcase the different Hydro Demolition techniques including manual, machine mounted and robotic systems.
It was also a great opportunity to showcase the Silver Raven team’s skill set.
Machine Mounted Hydro Scabbling
The demonstration began with a Scabbling Demonstration using the highly versatile X-Y Machine from Swedish company, Aquajet Systems.
This lightweight machine is designed for hydrodemolition operations in confined areas and wherever a robot or other types of equipment won’t fit.
A variety of depths were achieved by utilising different nozzles including the rotarhead and pinjet nozzles. The demonstration included precision control of the high-pressure water jets at 2,500bar for 20mm Scabble.
The purpose of the demonstration was to show how the steel reinforcement is both preserved and surface prepped for protective coating prior to re-pour of fresh concrete.

Robotic Hydrodemolition of Concrete
Always a ‘crowd-pleaser’ we set our Aqua Cutter 410V on course to jet a hole clear through 900 x 900 x 450mm block of concrete. Pumping at 480UHP/1300RPM at 75% the robot took just 12 minutes to blast clear through the concrete.
The Aqua Cutter 410V is specially designed for confined space applications and to replace hand lance work. Its small size and low weight allow the robot to easily pass through narrow passages, such as door frames or operate from scaffoldings.
A radio remote control allows operation of the Hydrodemolition Robot from a safe distance, wireless or with a hard wire.
Attendees were impressed with the result as the safety benefits as well as the ability to work in restricted spaces.

Hand Lance Demonstration
Utilising the latest technology in high-pressure water jets, manual hydro demolition lancing is the perfect alternative when robotic hydro demolition is not possible.
Many of our guests had never seen a hand-held lance demonstration.
Team member Jason Laurenson was the lucky one chosen to demonstrate the Hydro Demolition at 2600bar.
The Silver Raven hydroblasting operators and supervisors are Confined Space Trained, Demolition Licensed and have completed the ISI training course.
Cold Cutting Steel
Last but not least we moved indoors to watch a water-jet cut through a 16mm high strength steel tank. The picture below shows Michael Flannagan highlighting the magnetic jig which was fabricated at our Marrickville factory.
The day’s demonstration was powered by Silver Raven’s Fleet includes both Ultra High Pressure and Volume type pumps which range from 120 kW HDP to 480kW UHP.
