Cold fluid-applied (CFA) waterproofing membranes are becoming popular products for difficult flashing details, exposed roofing, split-slab, and plaza waterproofing applications. Members of the design and construction community—including developers, owners, contractors, and design professionals alike—are becoming increasingly interested in these products for their sustainability, ease of installation, and safety. When appropriately specified and installed, CFA membrane products can provide reliable, durable, and low-risk waterproofing solutions, particularly in hard-to-detail transitions or areas with limited exterior access. However, even the most experienced industry professionals can find it challenging to navigate and select an appropriate membrane product, due to their limited track record, numerous manufacturers, and variety of product chemistries and product types. Manufacturers typically publish testing data to assist professionals with their selection. However, testing is based on a variety of similar but different standards, making it difficult to compare membranes. Additionally, manufacturers typically publish testing of non-soaked samples, not considering the potential impact of in-service water absorption. To better understand and compare CFA membrane types, the authors conducted testing to evaluate water absorption properties of different dry samples, as well as puncture resistance and tensile strength properties of samples—both pre- and post-water absorption. They will discuss the benefits and challenges associated with CFA membranes, including the common and developing uses and detailing considerations. They will explain their testing methodologies, results, and findings.
