graffiti cleaning from underside of a stone bridge
CASE STUDY

Restoring a historical bridge; protecting nearby water from contamination.

The Project

This historical bridge graffiti removal job poses two challenges: soft brick can be prone to pitting and etching, and the site is located near a body of water. 

Other methods could destroy the substrate, but the wet (Dustless) process ensures that the surface will be preserved with no texturizing or pitting.

When blasting near a body of water, stray debris becomes a major concern. Because Dustless Blasting can be easily contained, it’s the perfect choice for environmentally sensitive areas such as this one.

Wet Blasting and the EPA

Uncontained emissions and debris from surface preparation operations, such as paint, coatings, paint chips and primers, can be toxic and lethal to aquatic life, can leach into the soil and be taken up by plants, bioaccumulate up the food chain and ultimately affect humans. 

One of the chief advantages of wet abrasive blasting over dry blasting is the reduced requirement for containment. Because the emissions and debris are encapsulated and weighed down by water, they can be effectively contained with fewer preventative measures.

“We worked closely with the chief environmental officer for the city as we were a few feet from a water course. We also had a few spectators from the city as it is a historical bridge, and they didn’t want any damage, which is why we blasted wet.”
