Ultra High Pressure Cleaning Treatment

Our equipment operates at variable pressures from 3,000 to 40,000 psi, enabling fast and effective removal of surface contaminants in diverse environments. Beyond cleaning, this pressure also removes existing coatings and can demolish concrete with precision unmatched by jackhammers or other manual tools. Learn more about our concrete remediation services.

Regular removal of surface contaminants like salts, chlorides, grease, oil, and sludge is vital, as it helps prevent concrete issues such as carbonation and concrete cancer. Once surface cleaning and preparation is complete we can complete a protective coating application if requested.

Featured Project

Queensland

Merivale Bridge

This project included application of a biodegradable degreasing solution to remove any grease, oil and other contaminants accrued over the years, pressure washing the surface with 5000 psi to remove all salt deposits and degreaser residue, and cleaning of all corroded surface areas t remove any mill scale and flaking paint.

Services

Our services include addressing structural issues, advanced protective coatings, and precise applications for long-lasting durability.

What is high pressure water cleaning used for?

High-pressure water cleaning removes contaminants such as salts, chlorides, grease, oil, and sludge. It also strips old coatings, prepares surfaces for new treatments, and helps prevent issues like carbonation and concrete cancer.

What surfaces can be treated?

Our cleaning services suit diverse surfaces including concrete, steel, and masonry. Whether for infrastructure or commercial projects, our adjustable 3,000–40,000 psi equipment tackles materials safely without causing damage.

Can high pressure water cleaning remove old coatings?

Yes, our equipment efficiently removes old or deteriorated coatings. With adjustable pressure settings, we strip surfaces precisely without damage, making it ideal for preparation or restoration projects.

How environmentally friendly is this cleaning method?

We prioritise environmentally safe practices by using biodegradable degreasers and ensuring proper waste management. Our procedures meet strict environmental standards, minimising impact while delivering effective cleaning solutions. All waste materials are safely collected, contained, and disposed of according to regulatory guidelines.

Does this method replace traditional demolition tools?

In many cases, yes. Ultra-high pressure water cleaning can locally demolish concrete and remove coatings with greater precision than traditional tools like jackhammers. This approach reduces dust, noise, and vibration, providing a safer and more controlled alternative for selective demolition tasks in sensitive environments.

Do you offer additional surface protection after cleaning?

Absolutely. After cleaning, we can apply protective coatings tailored to your specific needs. These treatments help extend the lifespan of your surfaces, providing resistance against future contamination and damage. Our integrated approach ensures your surfaces are not only cleaned but also protected against future wear and tear.
