Rationale

Hydrostatic pressure resistance is a common method of evaluating waterproofing materials. This ballot item proposes to add to C836 the same requirement for testing and reporting hydrostatic pressure resistance as is in D8463 Standard Speci?cation for High Solids Content, Cold Liquid-Applied Elastomeric, Silyl-Terminated Polymer Based Waterproo?ng Membrane for Use with Separate Wearing Course.
