The project shown is the 3-storey Union Bank of California building in downtown Sacramento.  The unfilled travertine exterior was very dirty from years of environmental exposure, and also had a number of cracked or damaged panels and panels which had come loose from their anchoring systems.  California Stone Care partnered with Natural Stone Design of Sacramento, a leading stone fabrication and installation company to repair and replace the loose and damaged panels.  Research determined that matching material was unavailable on the market, and the original source was identified and new stone was quarried and fabricated.

California Stone Care cleaned the building exterior completely using a marble-cleaning product manufactured by Prosoco, Inc. of Kansas City, Mo., and pressure washing equipment.  A sealant was then applied to protect the surface from moisture penetration and to facilitate future cleaning.
