    Abstract

    Building owners' expectations for waterproofing systems are simple. Waterproofing must prevent the passage of water (impermeability), must be capable of successful installation under typical construction conditions (constructability), and must continue to provide waterproofing for the life of the structure (durability). The realization of these expectations is thwarted, in part, by a lack of consensus on how these features are defined, tested, and compared to performance-based criteria. This investigation includes waterproofing materials commonly used on plazas and below-grade walls. The authors discuss important properties of waterproofing and review the requirements of standards for waterproofing systems. The results of testing bentonite and cold liquid-applied waterproofing are reported. In conclusion, the authors suggest improvements in standards.
