Technical surface cleaning with optimal dust control.
Wet sandblasting ensures effective removal of contaminants from concrete and metal, drastically reducing airborne dust. Suitable for industrial worksites in Italy, Europe and worldwide.
WET SANDBLASTING
Wet sandblasting and hydroblasting
Wet sandblasting and hydroblasting are ideal when surface treatment cannot be carried out in open areas or standard blasting cabins.
By injecting water into the abrasive stream, these methods drastically reduce dust emissions, improving operational safety and enabling interventions even in enclosed or environmentally sensitive areas.
Abrasives used include olivine sand, quartz, sodium bicarbonate, glass beads, Australian garnet, corn cob grit and other recyclable or natural materials.
- Objectives of wet sandblasting and hydroblasting
Remove damaged or contaminated surface layers
Prepare surfaces for coatings or treatments
Lower dust exposure during on-site operations
These processes are cleaner than traditional dry blasting, though slightly less aggressive due to the water. In projects where safety, environmental regulations and cleanliness are priorities — in Italy, Europe or globally — they offer the most sustainable choice.

Here's the difference between the two types of wet blasting:
Wet sandblasting
(water added at the nozzle)
When water is introduced externally into the blasting system, we refer to it as mist blasting. In this method, the abrasive is carried by a controlled mixture of air and water.
- Key characteristics:
Water and abrasive are mixed from the start.
Exceptional dust control, with minimal airborne particles.
Gentle on surfaces, making it ideal for restoration projects and sensitive materials.
Cushioned impact with low abrasive force.
Requires more water and specialised equipment.
Recommended for stone, marble, brickwork and monuments.
Slightly higher costs, but safer for delicate or historic surfaces.
Hydroblasting
(water mixed inside the machine)
When the water is injected inside the blasting nozzle and replaces air as the carrying medium, the process is known as hydroblasting.
- Key characteristics:
Based on dry blasting, with water added at the nozzle.
Good dust suppression, though some residue may remain.
Higher abrasive power, suitable for tough, industrial surfaces.
More aggressive cleaning, perfect for technical or heavy-duty work.
Lower water usage and simpler equipment setup.
Ideal for concrete, metal, and removal of paint, rust, or heavy deposits.
More affordable, best for non-sensitive materials.
Eco-friendly and safe solution
The choice between hydroblasting and wet abrasive blasting depends on the surface type and desired outcome. Hydroblasting offers a deep yet gentle clean with minimal impact on the underlying material and no airborne dust. Wet abrasive blasting maintains strong abrasive power for faster work while significantly reducing dust thanks to the addition of water. Both methods are environmentally friendly and safe, making them ideal for urban settings and sites with strict environmental regulations.
These techniques effectively prepare surfaces for subsequent treatments such as painting or protective coatings, whether in Italy, across Europe, or worldwide.
When and why to use hydroblasting or wet abrasive blasting
These two techniques are especially suitable when dry blasting cannot be performed in open environments or equipped blasting cabins, such as indoor settings or around dust-sensitive elements. Hydroblasting and wet abrasive blasting significantly reduce airborne dust emissions.
This makes them cleaner solutions compatible with enclosed spaces, although slightly less abrasive than traditional dry blasting.
Typical applications include:
Interior renovations
Cleaning radiators, handrails, stone surfaces, marble and granite elements
Graffiti removal
