All manner of concrete, steel, and stone rubble from dredging, demolition projects, and other construction is used as artificial reef materials. This material is generally available at very low cost or free from construction companies who are more than happy to get rid of it. Transportation costs determine where this material is used by the Reef Program.

Boilers are one of the most common shipwreck features, found on almost all engine-powered vessels. The purpose of a boiler is to produce high-pressure steam for the engine to propel the vessel. Steam boilers have been in use from the early 1800s to the present day.
