A brick ledge is a reinforced concrete bearing that sustains the weight of finished materials such as brick, stone, or other veneers acting directly on a footing or other foundation element (100 kg per square meter or more). In most cases, brick or stone veneer is applied to the exterior of a home or structure. The weight of this material needs to be supported by some kind of foundation. A brick ledge is required when using interior finish materials that are heavier than clay tile or wood paneling. Brick ledges are used under kitchen and bathroom sinks to prevent pipes from breaking under the weight of excess soil that may accumulate in those areas. They can also be used under appliances such as dishwashers and garbage disposals if there is danger of them being overloaded by waste products. Interior brick ledges are available in a wide variety of styles and colors to match any home decor. You should contact your local building authority to determine if interior brick ledges are required in your area. Exterior brick ledges are used where heavy equipment is likely to damage landscaping or where drainage is an issue. They can also be used where it is desired to create a decorative effect without having to use mortar. Brick ledges should not be placed over soil because excessive moisture could cause the bricks to decay or crack. Brick ledges should be located approximately 12 inches below the expected level of the surrounding floor and should be long enough to cover the entire length of the sink.
