Mortar Joints. The mortar used by the Contractor to reset the stone cladding on the south side of the historic Suitland Parkway Bridge will match in color and texture the original mortar on the south side of the bridge, will have greater vapor permeability and be softer (measured in compressive strength) than the masonry units, and will be recessed to the same depth from the stone surface as the current mortar on the south side of the bridge.
