In Hydro Demolitions, Ultra High Pressure Water Jetting is a utilitarian approach for removing debris on various surfaces. From concrete and steel surface preparation to internal pipe and storage cleaning, it has many applications.
As experienced specialist, we have to determine the right pressure for the right application and material. For instance, cleaning steel pipes requires a much different water pressure than cleaning wood surfaces. When skilfully executed, this method brings multiple benefits to clients.
What is Ultra High Pressure Water (UHP) Jetting?
Ultra High Pressure Water Jetting uses high-velocity water propellent to remove contaminants and other debris. In other words, it is an effective process for material surface cleaning. The force of the fast-moving water is strong enough to remove unwanted layers of old coatings upon impact, preparing the material surface for subsequent procedures like applying primers and paints.
Usually, the jetting system’s pumps obtain water from a reservoir, setting it under pressure in uniquely designed hoses that connect the source to the gun’s exit orifice. The water jetting gun’s trigger mechanism controls the valve. So when the valve is open, it releases pressurised water and projects at the surface.
What Are The Applications of Ultra High Pressure Water Jetting?
As mentioned, Ultra High Pressure Water Jetting can remove debris from various surfaces, including concrete, polymers, wood, steel pipes, copper statues and aluminium extrusions. Its most common application is cleaning substrates before coating works, as the coating can fail prematurely without proper surface preparation.
Operators also utilise Hydro Demolition for bridge rehabilitation, parking structures, water treatment facilities, damns and spillways, tunnels, and more.
Since UHP Water Jetting refrains from hazardous chemicals, it is also helpful for other cleaning processes. On the other hand, abrasive media blasting may cause residual solids accumulate, resulting in a disorderly work environment.
Benefits of Hydro Demolition
Unlike traditional hacking and breaking methods, Hydro Demolition does not render micro-cracking and damages to rebar. In fact, this non-impact solution adjusts water pressure to control precise depth removals, even removing concrete at partial depth.
Consequently, Hydro Demolition works effectively preserve the concrete’s structural integrity, including rebar conditions, steel reinforcements, and so on. It provides an excellent and high-quality bonding surface, ensuring no micro-cracks or fractures are rendered in the process.
Hydro Demolition is also a cost-effective and time-effective solution, as the enforced machinery works 30% more efficiently than traditional methods. Most importantly, it is a safe practice that mitigates injury risks for operators. As it removes concrete in a “controlled” manner without vibration, it also provides additional benefits such as:
- Limited noise pollution
- Reduced dust pollution
- Water can be collected for treatment or recycled for future projects
