Sandblasting is a technology for treating any surface using an abrasive material (sand) propelled by a jet of compressed air or liquid to a speed of about 960 km.
Sandblasting works very well in removing contamination from large surfaces, such as:
- industrial installations (towers, silos, transmission lines),
- steel and reinforced concrete structures,
- motor vehicle elements (car bodies, rims, trailers),
- agricultural and industrial machinery, land and sea containers, and many others.
Sandblasting was patented in the United States of America by Benjamin Chew Tilghman on 18th October, 1870.
