Hydrodemolition
Hydrodemolition for Structural Concrete Removal
Precision concrete removal without damage to the structure beneath.
Non-percussive, controlled removal for live infrastructure, repair and strengthening works.
- Selective concrete removal
- Reinforcement preserved
- No vibration, no impact
- Managed water systems
When breaking risks the structure
When conventional breaking risks the structure, hydrodemolition takes control.
Traditional mechanical breaking introduces vibration, micro-cracking and the risk of unintended damage — especially in critical structures. In live infrastructure, repair and strengthening works, that risk isn't acceptable. Hydrodemolition removes only the damaged or specified concrete — leaving the remaining structure intact, sound and ready for reinstatement.
What makes it different
Controlled concrete removal. Nothing more, nothing less.
Selective Removal
Removes deteriorated or specified concrete without overbreak.
Reinforcement Preservation
Leaves rebar clean, undamaged and ready for bonding.
No Vibration / No Impact
Protects surrounding structure and avoids micro-fracturing.
Managed Water Systems
Capture, filtration and pH control built into delivery.
Where it's used
Built for repair, strengthening and live environments.
Hydrodemolition is used where precision matters more than speed alone.
- Bridges and viaduct strengthening
- Reservoirs, tanks and water-retaining structures
- Marine and coastal infrastructure
- Nuclear and power generation facilities
- Live operational assets where vibration is not acceptable
Application gallery
Selective concrete removal without compromise.
Large surface removal
Consistent, depth-controlled removal across horizontal and inclined surfaces.
Reinforcement preservation
Defective concrete removed while maintaining structural steel integrity.
Controlled water management
Runoff captured, filtered and managed to meet environmental and site constraints.
Process & planning
Defined early. Delivered properly.
Hydrodemolition is most effective when it's planned as part of the wider sequence — not brought in as a last resort. We work with contractors to define:
- Removal depth and tolerances
- Access and sequencing
- Water management and environmental control
- Integration with follow-on works
Early definition removes risk, reduces rework and improves delivery certainty.

Where we work
Aquajet hydrodemolition, nationwide mobilisation.
Hydrodemolition mobilises from our Yorkshire head office and our Midlands and Hertfordshire depots — supporting current AMP8 water-industry delivery, motorway bridge maintenance, reservoir and dockyard programmes, and marine and coastal jetty works. The full Aquajet fleet, water-management and pH-control kit travels with each deployment.

FAQ
Hydrodemolition — common questions.
No — hydrodemolition is selective. The high-pressure water removes deteriorated or specified concrete while leaving the reinforcement clean, undamaged and ready for bonding. That makes it the standard method for concrete repair and strengthening.
Removal rate depends on concrete strength, reinforcement density and required depth, but on suitable substrates hydrodemolition typically outpaces handheld breakers significantly while delivering a more bond-ready surface — so follow-on reinstatement is faster too.
Yes. Equipment is calibrated for the specific concrete strength and the target depth — selective removal of cover concrete, removal to a defined depth, or full-depth removal can all be delivered to specification.
Capture, filtration and pH control are designed into the delivery from the outset. We work with site teams to integrate water management with environmental and discharge constraints, including in marine, water-retaining and live operational environments.
Where the structure cannot tolerate water exposure, where containment is genuinely impossible, or where the required removal volume is small enough that mobilisation overhead outweighs the benefit. We will say so up front rather than force the method.
