Hydroblasting is a technique for cleaning surfaces, which relies entirely on the energy of water striking a surface to achieve its cleaning effect. Abrasives are NOT used in hydroblasting systems. Consequently the problems caused by dust pollution and by the disposal of spent abrasives are eliminated.

The terms hydroblasting, hydrojetting and water jetting essentially mean the same thing with all being used to describe the same process. There can be confusion however over the difference between simple water washing and hydroblasting. To clarify the situation, International have adopted the following commonly accepted definitions.

Low Pressure Water Washing
Operates at pressures less than 69 bar (1,000 p.s.i.)

High Pressure Water Washing
Operates at pressures between 69-690 bar (1,000 - 10,000 p.s.i.).

High Pressure Hydro blasting
Operates at pressures between 690-1700 bar (10,000 - 25,000 p.s.i.)

Ultra High Pressure Hydro blasting
Operates at pressures above 1700 bar (25,000 p.s.i.) with most machines operating in the 2000 - 2500 bar range (30,000 - 36,000 p.s.i.)

Types of industrial surface preparation provided by PS Coating Solutions include

• Water jetting 3,000 PSI to 5,000 PSI
• High pressure hydroblasting, operating at pressures between 690 bar (10,000 p.s.i.) and 1700 bar (25,000 p.s.i.)
• Ultra high pressure hydroblasting, operating at pressures above 1700 bar (25,000 p.s.i.)
