Hydro Demolition

Hydro-demolition is a method of concrete removal that uses high-pressure water jets to break down and remove concrete from a structure while leaving steel reinforcement intact. Utilising a specialised nozzle operated either manually or through a robotic arm, this technique proves its versatility by efficiently tackling extensive concrete areas, reaching even the tightest and most challenging spaces.

At CSA, we are committed to deliver the best results to our valued clients. Our unwavering objective is to attain the highest level of service excellence without compromising the safety and well-being of our dedicated employees, subcontractors, the public, or the environment.

What Makes Hydro Demolition the Best Choice?

CSA’s advanced concrete removal methods provide a safer, more efficient alternative to traditional techniques. By eliminating vibrations, our process prevents micro-cracks in surrounding structures, preserving their integrity. Instead, our vibration-free, dust- and noise-reduced method preserves nearby materials, enhancing safety and limiting environmental disruption. Additionally, it creates an optimally rough surface, allowing for stronger bonding during repairs.

Selective Concrete Removal

Precise targeting ensures only necessary areas are removed, preserving surrounding structures.

Reduced Structural Impact

Vibration-free and non-intrusive, hydro demolition is ideal for high-risk structures like bridges, dams, and industrial tanks.

Environmental Safety

A dust-free and quieter process fosters safer conditions for operators and nearby communities.

Precision High-Pressure Water Blasting

Our work relies on Hammelmann high-pressure pumps, the industry’s leading equipment for power and accuracy. The Hammelmann 500 kW and 200 kW pumps, with pressures up to 3000 bar, effectively remove concrete in reinforced structures, handling demanding environments without compromising on safety. These pumps, particularly the HDP 500 models, are adaptable for remote or restricted sites, with options for container or truck mounting to suit project needs.

CSA’s Key Hydro Demolition Applications

Bridge and Road Infrastructure:
Ideal for selectively removing damaged concrete while protecting rebar during resurfacing projects.
Dams and Reservoirs:
Suitable for high-moisture and submerged conditions, maintaining structural stability.
Marine and Coastal Structures:
Ensures safe, vibration-free work in sensitive underwater environments.
Industrial Facilities:
Supports clean and efficient upgrades in wastewater plants and industrial settings.
Tunnels and Overhead Projects:
Provides safe solutions for confined spaces and overhead demolitions without risking structural integrity.

Industry-Leading Vacuum Extraction Systems

To complement our water blasting capabilities, CSA’s advanced vacuum units extract liquid washings and debris efficiently over distances exceeding 200 metres. This capability supports environmental responsibility by minimising on-site contaminants, crucial for complex projects such as dam wall scabbling. The range and capacity of these units contribute to CSA’s commitment to environmentally sound site management.

Heat Exchanger and Pipework Cleaning

Our use of the advanced Peinemann flex lance system enables our operators to conduct thorough and safe cleaning of internal tubes, along with meticulous high-pressure washing of all surrounding surfaces. The innovative design of the spinning heads on our equipment ensures an effective cleaning process that preserves the structural integrity of the tubes.

Our revolutionary spinning heads on flex lances ensure a thorough clean without tube damage. Using high-pressure water is the most effective way to eliminate scale and fouling, restoring heat exchangers to peak efficiency.

Comprehensive Project Management and Safety Compliance

CSA brings both technical expertise and advanced equipment, alongside a team committed to high safety and compliance standards. Our emergency liquid waste management response team is equipped with dangerous goods capabilities to respond swiftly to spills or waste needs. Each project is planned meticulously, with flexible day-rate pricing to provide transparent budgeting options. Any necessary adjustments due to heavy buildup or material characteristics are promptly communicated, ensuring clear, efficient project progression.
