Restoration work within the UNESCO World Heritage Galle Fort is overseen by the Central Cultural Fund and Archaeology Department. Modern Portland cement is prohibited on historical walls; its rigidity and low vapor permeability traps moisture within the porous coral stone and kabook (laterite) masonry, accelerating structural decay. Masons must use traditional lime mortar formulated from slaked shell lime, fine river sand, and traditional organic additives like jaggery water and bael fruit mucilage to ensure breathability.
