Waterproofing involves the vertical surfaces of a building—the building's façade. Certain surfaces represent the more common entry points for water, and it is here that AM&G focuses its waterproofing efforts: on the corners, spandrels, lintels, columns, window jambs, headers, sills, and the building's “eyebrows”—the strip of concrete or “deck” that protrudes along the outside the building. All of these elements need a top-notch waterproofing system behind them to make sure water does not enter the structure. We use different types of waterproofing systems — Kemper, Liquid Plastics, and Grace products —depending on the needs and condition of the building.
Not only should there be waterproofing behind the brick or element, there is often a coating in front of the element—a clear water repellent over the surface.
Exposed elements like balcony decks and ceilings face harsh weather and changing temperature. They can crack, letting water behind or into the element, which, in turn, can break the concrete. These elements need to be patched and coated with a proper system to prevent further damage.
Access to these vertical facades is often difficult, and varies from building to building. AM&G has worked on buildings using simple scaffold, and on multiple setbacks where access must be set up via pipe scaffold. AM&G has regularly worked on difficult setbacks where specially designed outrigger systems must be used.
