(USA), a large fire broke out in a restaurant during its ongoing remodel. Located along the Chesapeake and Ohio Canal in the bustling neighborhood of Georgetown, the fire left heavy soot (about 20-30 mils) on a variety of different substrates inside the building, including brick, concrete, stone, and wood.

The large-scale granite restoration project included onsite blasting by [United Stone](http://www.unitedstoneandsite.com/), as well as dismantling the bridge’s iconic Rockport granite “salt and pepper” towers piece-by-piece, and then transporting them to nearby workyards in Charlestown via barge for offsite restoration. The now pristine towers were reassembled using a mix of modern and historic construction technology. Skilled masons at United Stone were able to clean ornate granite carvings as well as the large granite blocks using the same equipment and media.

Marble has been used in buildings and structures for millennia dating as far back as the ancient Greeks in the [7th century BCE](http://www.ancient.eu/Greek_Architecture/). Marble mining remains a global industry with quarries spanning across six continents. As marble has been used for centuries as a building material, many buildings and structures around the world contain marble that is showing its age with discoloration and staining.

Companies that clean, restore, or prepare concrete and stone now have a greater job site responsibility related to respirable crystalline silica that becomes airborne during this process. In their Final Rule, OSHA has reduced the permissible exposure limit (PEL) for respirable crystalline silica to 50 micrograms per cubic meter of air, averaged over an 8-hour shift. To lower airborne silica created by construction processes, OSHA is requiring companies to add engineering controls to concrete, stone and other masonry cleaning and repair processes.
