One of our most challenging projects, completed in 2013 — internal and external cleaning of the station's heritage sandstone surfaces.

• Sandstone Cleaning: Removal of built-up dirt, pollution and calcium salt deposits from the soft heritage sandstone.
• JOS RotoSoft System: A gentle, low-pressure rotating vortex cleaning method ideally suited to soft heritage sandstone, removing contaminants without damaging the substrate.
• Result: A clean, uniform finish with the heritage fabric fully preserved — avoiding the need for costly repair work.

The sandstone was returned to a clean, uniform finish while fully preserving the heritage fabric of this landmark building — documented in 27 before-and-after photo pairs.
