Three Times When Hydro Jet Cutters Are The Only Choice
One of the biggest growing trends in construction and demolition is the use of highly pressurised water to help remove deteriorated material and create a perfect bonding source for new concrete or asphalt.
The reason why hydrodemolition is so sought after is that it lacks many of the problems traditional saws, drills and pneumatic machines have. It produces less noise, no dust pollution and thanks to technological advances, the water used in the process can be easily cleaned and reused.
However, beyond times when it is a desirable choice, especially as construction firms look to reduce their carbon footprint, there are times when hydro-jetting is not just the best choice, it is the only choice.
Here are three of the biggest examples of this.
Cleaning And Taking Apart Fuel Tanks
Pressurised tanks and tankers are commonly used to transport petrol, natural gas, volatile chemicals and all manner of potentially hazardous materials, and can be found at petrol stations, oil rigs and chemical manufacturing plants.
When the time comes for these tanks to be decommissioned and taken apart, many common cutting tools simply cannot be used. Plasma cutters and blow torches use flames that can cause the residue in a tank to ignite, and many types of saws cause sparks as a result of friction.
Hydro jet cutting therefore can be highly effective at cutting into tanks, cutting tanks into pieces and forcibly disconnecting pipes in situations where generating sparks could create a major incident.
Structural Concrete Repairs
One of the most important building materials of the 20th century was concrete. Once the concept used to make Smeaton’s Tower was strengthened via techniques innovated by Joseph Monier, it became one of the materials that helped us build higher and higher.
The problem with concrete, however, is that its incredible compressive strength is matched by its weakness to tensile forces, which is the main cause of cracks in larger structures such as skyscrapers and bridges.
Most of the methods used to repair and replace concrete produce vibrations that reverberate throughout the structure, creating micro-fractures that make the situation worse.
Hydro scarification removes the top surface of a bridge or road and creates the optimal conditions for a new layer of concrete to be laid down.
Given that other tools can cause major structural damage, hydro-jetting is often the only choice.
One less drastic but otherwise incredibly important use of hydro-jetting is a life-saving technique to ensure aircraft land safely.
Upon landing on a runway, the plane’s wheels will shed rubber as part of the braking process, which over time can accumulate and have a dramatic effect on the level of grip the runway has.
If there is too much rubber down, there is less friction, causing the potential for skidding and more space needed for landings, which can potentially be catastrophic if the runway is too short or the weather is particularly precarious.
This is where hydro jet technology can assist, as the abrasive high-pressure wash can be used to get rid of built-up rubber and improve the friction of the runway itself.
