Preservation-grade laser cleaning of 18th-century hand-molded brick and Aquia sandstone in historic Alexandria, VA.
Decades of vehicular exhaust soot and black gypsum crusts disfiguring delicate 18th-century brickwork. Chemical washes and micro-abrasives caused irreversible erosion to historic surfaces.
Abrasive grit blasting presented unacceptable risks of substrate thinning, environmental contamination, or facility shutdown.
Photonic light pulses selectively heated and vaporized black carbon deposits while reflecting harmlessly off underlying natural clay and mineral matrices.
â 100% preservation of ornamental carving and brick surfaces. Zero water runoff or chemical residue. Unanimously approved by Local Architectural Review Board.
500W Nanosecond Pulsed Conservation Laser with precision optic delivery.
Integrated 3-stage HEPA containment capturing 99.97% of particulates down to 0.3Ξm.
Waste Generated: 0 gal Chemical Wash Runoff. Zero abrasive runoff.
