New Specification for High Solids Content, Cold Liquid-Applied Elastomeric, Silyl-Terminated Polymer Based Waterproofing Membrane for Use with Separate Wearing Course

1. Scope

The promotion of knowledge, stimulation of research, and development of standards pertaining to materials and systems for roofing and waterproofing, for related building, industrial, and agricultural uses. These activities shall be coordinated with those of other ASTM committees and national and international organizations having similar interests.




Over the past 15 years there has been a significant increase in the use of STP (Silyl-terminated polymer) based waterproofing such that it has become recognized as a primary technology for this application. STP based technology has inherent differences in properties and performance when compared to alternative liquid applied waterproofing membranes. This specification serves to give direction to manufacturers and minimum performance requirements to end users so as to allow for better decision making and differentiation between products. Given the growth in this technology and the range of products offered by a multitude of manufacturers it is appropriate to have a stand-alone standard in ASTM. This is consistent with other ASTM standards which differentiate on the basis of polymer technology.

The title and scope are in draft form and are under development within this ASTM Committee.
