TESTING REINFORCED-CONCRETE STRUCTURES FOR WATERTIGHTNESS

The American Concrete Institute Committee 350, Environmental Engineeri ng Concrete Structures, recognized a need for standardized criteria as well as a standardized method of testing reinforced concrete structur es for watertightness. AWWA's Committee 400, Waterproofing, was also i nterested in documenting the state-of-the-art of watertightness testin g and criteria for reinforced concrete tanks. A joint subcommittee was subsequently formed to prepare a report containing recommendations on watertightness for reinforced concrete containment structures. This a rticle presents the findings of the joint report.
