ASTM C1715/C1715M-21 PDF Download

The ASTM C1715/C1715M-21 standard is a test method that outlines a procedure for evaluating the water leakage performance of masonry wall drainage systems. The purpose of this test is to measure the ability of the drainage systems to collect and redirect water that infiltrates the exterior masonry wythe during rainstorms.

This standard is specifically designed for wall systems that feature an exterior masonry wythe with a drainage zone on the interior face. However, it is important to note that it is not applicable to single-wythe drainage walls or masonry walls that do not have drainage zones behind the exterior wythe.

The objective of this test method is to ensure the effectiveness of masonry wall drainage systems in preventing water intrusion and minimizing the potential for moisture-related issues such as mold, deterioration of materials, or structural damage. By conducting this test, builders and construction professionals can assess the water leakage performance of masonry wall drainage systems and make necessary improvements to ensure optimal functionality and long-term durability.
