What Is Robotic Hydrodemolition?

Robotic hydrodemolition is an advanced method used for removing concrete or other materials from surfaces using high-pressure water jets. In this process, robotic equipment equipped with water jetting nozzles is controlled remotely to precisely target and remove concrete, coatings, or other unwanted materials from structures such as bridges, dams, or buildings.

The high-pressure water jets effectively break down the material without causing damage to the underlying structure. Robotic hydrodemolition offers several advantages, including increased safety for workers, precise control over the removal process, and reduced environmental impact compared to traditional demolition methods.

What Is Robotic Hydrodemolition?

At A L Hydrojetting we pride ourselves in operator safety and by purchasing the world’s leading manufacturer of robotic Hydrodemolition equipment, our Aqua Cutter 410A Hydrodemolition robot fits that bill and is the perfect tool for removing any unwanted concrete safely.

With its Radio remote control, it offers us and our client some extra peace of mind knowing the task can be done safely, the Aqua Cutter robot allows our operatives to stand at a safe distance to control and supervise the operation away from the danger zone, but also still allowing full control of its movements.

The Aqua Cutter 410A is small in size, weighs 1.2T and has a reach of 3m it can withstand extremely high reaction forces, allowing the use of much larger pumps, increasing product activity. Its versatile articulated arm can reach horizontal, vertical and overhead areas, making the robot, powerful and very easy to position.

Advantages of Robotic Hydro-Demolition


Robotic systems provide precise control over the removal process, ensuring accurate targeting of areas needing demolition while minimising damage to surrounding structures. With the Aqua cutters EDS System (Equal distance system) allows a preset distance from the nozzle to the concrete surface, regardless of the attack angle of the water jet. Keeping the same distance and an even finish during the whole operation.


By allowing operators to control the process remotely, robotic hydrodemolition enhances worker safety by reducing the need for personnel to work in hazardous environments or near heavy machinery.


Robotic systems can work continuously and efficiently, maximising productivity and minimizing downtime compared to manual methods.

Reduced Vibration

The controlled application of high-pressure water minimises vibration, reducing the risk of structural damage to surrounding areas and limiting the need for additional repairs.

Environmental Friendliness

Hydrodemolition eliminates the use of harmful chemicals and reduces dust and airborne particles, making it an environmentally friendly option for demolition projects.


Robotic hydrodemolition can be used in a variety of applications and on different surfaces, including concrete, asphalt, and steel, making it a versatile solution for various demolition needs.

Cost Effectiveness

While initial investment costs may be higher, robotic hydrodemolition can lead to long-term cost savings due to increased productivity, reduced labor costs, and minimised damage to structures.

Safety Measures

The use of robotic Hydrodemolition removes the operative away from the danger, using its radio remote control allows the operative to stand at a safe area away from the danger zone but also in full control of the operation and surroundings.


Robots are increasingly utilised for hydrodemolition, a method of removing concrete or other materials using high-pressure water jets. This innovative approach offers several advantages over traditional methods, including increased precision, efficiency, and safety.

Using robots for hydrodemolition minimises the risks associated with manual labour, such as exposure to hazardous environments and heavy machinery. Additionally, robotic systems provide precise control over the removal process, ensuring accurate targeting of areas needing demolition while minimising damage to surrounding structures.

In contrast, traditional methods of demolition, such as manual drilling or jackhammering, pose significant challenges, safety risks, and inefficiencies. These methods are labour-intensive, time-consuming, and often result in an uneven or incomplete removal, leading to additional repair costs and project delays.

When it comes to hydrodemolition, companies have the option to use either dry or wet demolition robots. Dry demolition robots utilize mechanical methods, such as sawing or drilling, to remove materials, while wet demolition robots use high-pressure water jets to break down concrete or other surfaces.

So, what is the difference between dry and wet demolition robots? While both methods offer their own set of advantages, wet demolition robots are particularly well-suited for projects where precision, safety, and environmental considerations are paramount. By harnessing the power of water, wet demolition robots provide a highly effective and eco-friendly solution for demolishing concrete and other materials, ensuring optimal results with minimal disruption

What are dry demolition robots?

Dry demolition robots are robotic machines designed for mechanical demolition tasks, such as cutting, drilling, or breaking down concrete, asphalt, or other materials without the use of water. These robots are equipped with specialised tools, including saws, breakers, or drills, which are operated remotely by an operator.

Dry demolition robots are commonly used in construction, renovation, and demolition projects where precision, efficiency, and safety are paramount.

They can perform a wide range of tasks, including cutting expansion joints, removing floor coatings, breaking up concrete slabs, and drilling holes for anchor bolts.

What are wet demolition robots?

Wet demolition robots are robotic machines designed to perform demolition tasks using high-pressure water jets.

These robots are equipped with specialised nozzles that spray water at extremely high pressures, typically ranging from 10,000 to 40,000 pounds per square inch (psi), to break down and remove concrete, asphalt, or other materials.

Wet demolition robots are commonly used in construction, renovation, and demolition projects where precision, efficiency, and environmental considerations are important. They are particularly effective for removing concrete from surfaces, cutting through reinforced concrete, and breaking up asphalt.

Which Is Best?

Determining which method is best, whether wet or dry demolition robots, depends on various factors such as the specific requirements of the project, environmental considerations, and the materials being demolished.

For projects where precision, minimal dust, and environmental friendliness are top priorities, wet demolition robots may be the preferred choice. They offer precise control over the demolition process, utilise water as a cutting agent, and minimise dust and airborne particles, making them suitable for indoor or sensitive environments.

On the other hand, dry demolition robots may be preferred for projects where water management is challenging, or where noise and vibration are concerns. They offer versatility and can perform a wide range of demolition tasks without the need for water, making them suitable for outdoor projects or environments where water usage is restricted.

Ultimately, the best method depends on the specific requirements and constraints of each project. Consulting with experienced professionals and considering factors such as project scope, site conditions, and environmental regulations can help determine the most suitable approach for achieving the desired demolition outcomes.
