UHP Water Jetting Services: Advanced Surface Preparation
At SPG, we specialize in Ultra High Pressure (UHP) Water Jetting, a cutting-edge method of surface preparation that delivers superior results while maintaining environmental safety. With pressures ranging from 25,000 to 36,000 psi, our water jetting process uses only the power of water—no abrasives—to effectively remove coatings, contaminants, and soluble salts from a wide range of surfaces.

What is UHP Water Jetting?
UHP Water Jetting utilizes the energy of water striking a surface to remove coatings and contaminants. Unlike traditional methods, it relies on sheer energy rather than tensile force, making it highly efficient for even the toughest surface preparation tasks. When the water pressure surpasses the removal threshold energy of a coating, the material is completely stripped away, leaving a clean and prepared surface.
As part of the process, some of the kinetic energy converts into heat, which raises the temperature of the substrate. This accelerates water evaporation and surface drying. However, the exposed steel surface may develop light surface oxidation, known as flash rusting, which is a normal outcome of this method.
Key Benefits of UHP Water Jetting
- No Abrasives Required: Clean surfaces effectively using only water, eliminating the need for abrasive materials.
- Soluble Salt Removal: Removes invisible surface contaminants and soluble salts, ensuring a high-quality substrate for coating application.
- Environmentally Friendly: Produces minimal airborne contaminants compared to dry abrasive blasting.
- Fast Drying Time: Surface heat from the process accelerates drying, saving valuable project time.
- High Efficiency: Quickly removes coatings and surface materials, making it ideal for large-scale or time-sensitive projects.
Wastewater Containment and Filtration
At SPG, we prioritise environmental responsibility by implementing robust wastewater containment and filtration systems. This is especially crucial when removing coatings that contain hazardous substances like lead. Our advanced systems capture, filter, and safely dispose of all wastewater, ensuring compliance with environmental regulations and minimising ecological impact.
