Find current ASTM designations for below-grade waterproofing membranes (sheet vs. fluid-applied) and confirm they haven't been withdrawn

Steps

1. Fluid-applied, separate wearing course: ASTM C836/C836M (High Solids Content, Cold Liquid-Applied Elastomeric Waterproofing Membrane for Use with Separate Wearing Course) is the current designation for hydrostatic-rated liquid membranes overlaid by a topping — verify the current reapproval year (e.g., "-18r22") on astm.org/store before citing.
2. Fluid-applied, integral wearing surface: ASTM C957/C957M covers the same membrane family without a separate topping.
3. Cross-type performance guide: ASTM D7832/D7832M (Performance Attributes of Waterproofing Membranes Applied to Below-Grade Walls) lists minimum performance attributes applicable to both sheet and fluid-applied wall membranes — useful for performance-based specs.
4. Sheet membranes have no single umbrella ASTM specification comparable to C836; self-adhering rubberized-asphalt and composite sheet products are typically qualified against individual property test methods and ICC-ES evaluation reports rather than one designation — verify the manufacturer's cited test methods directly rather than assuming a universal sheet standard exists.
5. Confirm every designation on ASTM's own product page before publishing a spec — standards get reapproved, revised, or withdrawn (e.g., D6135, a self-adhering sheet practice, was withdrawn in 2014).
