Structural Steel Repair

The majority of displaced masonry can be attributed to underlying structural steel corrosion. After masonry removal and required shoring, the structural steel is cleaned of all scale and rust. The most common repair is to add plate, channel and/or angle sections to reinforce existing steel. The extreme cases would be full removal and replacement of existing steel. Rust inhibitive coatings and waterproofing would then be applied prior to the installation of new masonry.

Sealants 0


Sealants can be used in various applications such as windows, control joints, wash surfaces or to bridge dissimilar materials.



Waterproof coatings seal the surface from liquid and from water vapor. They usually are opaque, such as bituminous coatings and some paints. Water repellents keep liquid from penetrating the surface but also allows masonry to breathe.

Coping Covers

Coping Covers

Copings are a key element to waterproofing, as they are located at the top of walls and subject to direct water exposure. Poor sealing, insufficient protection and not enough angle are some of the reasons for needing coping cover alterations or replacement.

Flashing Old Brooklyn Courthouse


Improper or no flashing on facade elements can be the clear cause of deterioration and water infiltration. Lack of drip edge on projecting elements can also lead to deterioration and present a need for flashing. Analysis is the key to solving any of the problems.

Lintel Steel & Stone


In older buildings, very often the steel will rust and the lintel and/or steel shelf angle will need replacement. Experience is needed for a potentially dangerous job. Masonry is shored, if needed, when the original lintel is removed. A new rust inhibitive lintel is installed and waterproofed prior to the installation of new masonry.
