    Abstract

    Water permeance of exterior masonry wall systems drives masonry restoration and repair design decisions from selection of flashing replacement to pointing to application of water repellents. ASTM C1601 was first issued in August 2004 and has not been used extensively in service by professionals to evaluate masonry wall surfaces. ASTM C1601 provides a standard method of measuring water permeance that can be used to evaluate existing wall surfaces prior to specifying repair methods and as a tool to evaluate the overall effectiveness of repair methods so that efficient repair options can be selected. This paper reviews the requirements of the test method, application of the test method and interpretation of test results. Historical test data are presented that illustrate use of the test method to evaluate wall systems and expected range of test results for existing and repaired wall systems that can be used to select appropriate repair procedures.
