Essential Requirements for Waterproofing
Waterproofing materials standards contain both requirements that are specific to the material described and requirements for properties that are essential to any waterproofing system. For example, nonvolatile content may be useful in distinguishing between cold liquid-applied waterproofing materials; but, it is a property that has little relevance to other kinds of waterproofing. On the other hand, the capacity to bridge cracks is important to any waterproofing. In the review that follows, we have attempted to identify requirements within existing material standards that indicate essential requirements for waterproofing. To set a manageable scope for this paper, we limited our review to two properties each in the three broad areas of impermeability, constructability, and durability.
