Bughole-induced outgassing

From Wikipedia, the free encyclopedia

Bughole-Induced Outgassing is a phenomenon occurring when applying a protective coating (or lining) to concrete (predominantly vertically cast-in-place) where air becomes entrapped within bughole cavities and releases into or through the protective coating, thereby causing pinholes and holidays in the coating film.[1]

As a requirement of the SSPC-SP13/NACE No. 6 Surface Preparation of Concrete Joint Standard, bugholes are to be filled prior to coating application.[2]
