This detail illustrates a composite mortar repair installed in an existing masonry unit (e.g. stone, terra cotta, cast stone, etc.) where a previous spall, multiple-cracks, or delamination existed. Composite mortar repairs are cementitious materials and fine aggregates (e.g. sand) blended with water. For composite mortar repairs to be durable and resilient it is important to take into consideration the following: Material properties of the repair mortar should match the original masonry unit receiving the repair, including strength, porosity/density, water absorption, and vapor permeability; Preparation of the repair area should include keyed perimeter edges, uniform depth, surface roughness, clean, and stainless steel supplemental anchorage; Installation of the composite mortar should include surface moisture content as required, base coat, initial and finish coats, finishing to match profile, and curing as required; Quality control should include repair mockups prior to start of

This wall system illustrates an example of a mid to high-rise transitional, or hybrid masonry wall. This type of construction was common between 1890-1940 and varies widely as it was a part of the transition from mass masonry load-bearing wall construction to steel skeleton frame construction. In this example the steel structural system supports floor loads and is encased in concrete and a 12” multi-wythe brick wall with stone veneer that encloses the building. The 4” stone veneer is tied into the masonry by metal z-strap anchors and at the top course by a metal cramp whereas the common brick is used as the backing and predominant wall infill. The anchors engage with the veneer stone by penetrating a kerf or channel that is cut into the top surface of each panel. The mass of masonry deflects bulk water penetration but is understood to take on a percentage of moisture that is free to evaporate slowly from the mortar joints on either side of the wall over time.

In this example the steel structural system supports floor loads and is encased in concrete and a 12” multi-wythe hollow clay tile wall with brick veneer that encloses the building. The facing brick is utilized as a veneer, whereas the hollow clay tile is used as the backing and predominant wall infill.

This wall system illustrates a 4” ashlar veneer with brick backing. The coursed ashlar veneer is tied to a 12” brick backing with metal “Z” veneer anchors and at the top course by a metal cramp. The anchors engage with the veneer stone by penetrating a kerf or channel that is cut into the top surface of each panel. The mass of masonry deflects bulk water penetration but is understood to take on a percentage of moisture that is free to evaporate slowly from the mortar joints on either side of the wall over time. The wall is topped with a splayed copestone that prevents water penetration and has drips at either underside edge to direct water away from running down the façade.

This wall system illustrates a coursed ashlar wall with uncoursed, squared rubble stone backing. The coursed ashlar varies in dimensions of 4-16” at bonding stones. The bonding stones are full depth of wall and tie that wythes of masonry together, whereas the smaller stones are considered veneer, though they are loadbearing. The lower four courses of ashlar are quarry-faced with smooth finish ashlar above.

This wall system illustrates a typical load-bearing low to mid-rise mass masonry rubble wall. The 16” wall consists of uncoursed, squared rubble stone that typically rests on a stone foundation below grade. This wall could also consist of exterior wythes of coursed rubble stone with an interior of rubble fill. The mass of masonry deflects bulk water penetration but is understood to take on a percentage of moisture that is free to evaporate slowly from the mortar joints on either side of the wall over time. The wall is topped with a saddle copestone that prevents water penetration and has drips at either underside edge to direct water away from running down the façade.

This wall system illustrates a typical load-bearing low to mid-rise mass masonry brick wall with rubble foundation. The rubble foundation extends above grade to create an uncoursed, squared rubble water table, topped by a cut stone plinth course. The plinth course acts as a bonding course as well as creates a level base for the brick wall above. Above stands a 16” common bond brick wall. The exterior wythe consists of facing brick whereas the inner wythes consist of common brick. The wall does not contain an airspace or secondary layers. The mass of masonry deflects bulk water penetration but is understood to take on a percentage of moisture that is free to evaporate slowly from the mortar joints on either side of the wall over time. At the top of wall is a splayed copestone with drips at either side to prevent water penetration and to direct water away from running down the façade.
