sentences:  In hydro-blasting, a highly pressured stream of water is used to remove old paint, chemicals, or buildup without damaging the original surface.This method is ideal for cleaning internal and external surfaces because the operator is generally able to send the stream of water into places that are difficult to reach using other methods.Another benefit of hydro-blasting is the ability to recapture and reuse the water, reducing waste and mitigating environmental impact.
