Chimneys built of brick – with heights ranging from 50 - 250 feet – serve numerous types of facilities by venting the gaseous byproducts of onsite power generation or incineration of hazardous waste. However, for all of their seeming permanence, these chimneys, particularly those constructed of radial brick, require regular maintenance and repair to remain operational and to maximize their useful life because they are constantly being attacked by Mother Nature, lightning, and combustion byproducts.
Radial brick are curved on their outer face to a specific radius, making round chimneys easier to construct. The tighter circles permitted by the radius of the brick faces, coupled with the added strength of the keyed joints, allow radial brick chimneys to achieve greater heights with smaller diameters at the base.
Few, if any, radial brick chimneys are built in the United States today, primarily because the scaffolding systems used in their construction are not safe by current standards. In fact, there is only one company producing radial brick for chimney construction. However, despite the absence of new radial brick chimney construction, the large inventory already built throughout the United States requires a focus on maintenance.
