Description: Bugholes, pinholes, blowholes, surface voids—they’re called by various names, but all refer to a common problem that contractors want to avoid. Bugholes, as they’re usually referred to in the U.S., are small regular or irregular cavities, usually not exceeding 5/8 in. (16 mm), resulting from entrapment of air bubbles in the surface of formed concrete during placement and consolidation. This 4-page bibliography lists and abstracts some helpful articles, Web sites, official guidelines, and reports that explain bugholes and recommend solutions.
