This test procedure provides the building owner & building designers with a method for testing the watertightness of waterprooﬁng installations applied to horizontal surfaces (Roofing systems) this procedure is intended for checking waterprooﬁng installations on flat roof installations over habitable spaces.
Applicable waterprooﬁng membrane installations that are regularly tested are fully adhered or bonded sheet membranes, liquid or ﬂuid applied membranes, or loose laid sheet membranes. Flood test is completed if no leaks are determined to have occurred during the test period and the membrane and ﬂashings are intact (for example, no blistered). For more information on the technical aspects of this testing contact us for more information.
The testing should be performed only after waterprooﬁng membrane and ﬂashings are inspected and any deﬁciencies repaired.
