This monument serves as a memorial for astronaut Gus Grissom: a Mercury astronaut & America's second man in space.
One of our contractors, who is actually Gus Grissom’s third cousin, had the opportunity to clean up the monument, which was covered with years of grime.
Limestone is a porous, delicate substrate that can be damaged by other methods. The city ﬁrst attempted to clean the monument with pressure washing, which chipped away the soft stone and damaged the lettering.
Dustless Blasting was the ideal solution, not only because it cleaned the limestone without damage, but also because it required no bulky containment.
"[The city] loved it, because they've seen water towers getting done, where people set up big containment structures. And you don't need to with this machine. It all falls right to the ground and it doesn't go anywhere, it doesn't make a big mess, it cleans wonderfully."

Pressure and flow are adjustable, for cleaning a variety of surfaces including concrete, brick, limestone, and more.
Since the dust plume is suppressed, you can work safely near buildings, roads, and people with minimal containment.
Compared to pressure washing, Dustless Blasting cleans more quickly and uses far less water. See Comparison.
