Specification for Tightness Testing of Environmental Engineering Concrete Containment Structures(ACI 350.1-10) and Commentary

Description

1.1.1Work specified—This Specification covers tightness testing of liquid and gaseous environmental containment structures designed to resist liquid or gaseous loads. Provisions of this Specification shall govern except where other provisions are specified in Contract Documents.

1.1.1.1 These test methods are for the tightness testing of concrete environmental engineering liquid and gaseous containment structures. The included tests are:(a) Hydrostatic tightness test for open or covered contain-ment structures.(b)Surcharged hydrostatic tightness test for closed containment structures.(c)Pneumatic tightness test for closed containment structures.(d) Combination hydrostatic-pneumatic tightness test for closed containment structures.

1.1.1.2 The tightness testing procedures and requirements contained herein are applicable to reservoirs, basins, andtanks constructed of concrete or a combination of concreteand other materials. Preparatory items indicated arerequired, unless otherwise specified, but the waiver of suchitems shall not change the test criteria.

1.1.1.3 Each cell of multi-cell containment structuresshall be considered a single containment structure and testedindividually unless otherwise permitted.

1.1.1.4 The hydrostatic tightness testing procedures andrequirements herein are also applicable for tightness testingof open concrete liquid transmission structures such as cast-in-place concrete channels and conduits.

1.1.1.5 The hydrostatic tightness testing procedures and requirements herein, where applicable, can be used for tightness testing of concrete paved structures, such as channels andimpoundments.1.1.2Work not specified—These provisions are not intended for hazardous material primary or secondary containment structures, cryogenic storage structures, high-pressure gas tanks, or miscellaneous precast concrete structures such as culverts, pipes, and manholes.
