Aquajet Evolution 3.1 and Ecosilence 400 hp: hydrodemolition notes for engineers
Reviewed by Joe Ashwell

First reported on The Construction Index
30 Second Briefing
Hydrodemolition specialist Aquajet has released the Evolution 3.1 control system alongside three dedicated Aqua Cutter 450 attachments and a 400 hp Ecosilence high-pressure pump unit. Evolution 3.1 introduces updated process control for concrete removal, enabling more precise jet positioning and automated parameter adjustment on Aqua Cutter robots. The 400 hp Ecosilence package is designed to deliver stable high-pressure water for thick-section concrete and heavily reinforced structures while reducing on-site noise and fuel use compared with earlier units.
Technical Brief
- For asset owners, higher hydrodemolition precision supports selective removal around congested reinforcement, reducing patch repair volumes.
Our Take
The Evolution 3.1 control system and the three dedicated Aqua Cutter 450 attachments signal that Aquajet is betting on modular, software-driven upgrades rather than entirely new carrier platforms, which typically lowers lifecycle cost for fleet owners on long-running infrastructure rehabilitation programmes.
