ASTM D6622/D6622M-20 PDF Download

ASTM D6622/D6622M-20 is a standard guide that provides procedures and precautions for the application of fully adhered hot-applied reinforced waterproofing systems. The guide outlines the minimum installation recommendations for these systems on vertical and low-slope surfaces, such as plaza decks.

It is important to note that this guide is not comprehensive and is intended to supplement detailed instructions from designers and the recommendations of manufacturers. Manufacturers may have proprietary products and special procedures that are not covered in this guide, so their recommendations should be considered during the application process.

The substrate for the waterproofing system is assumed to be structurally sound concrete or masonry that meets the local building code requirements and is able to support anticipated loads. The guide also assumes that all components of the system comply with relevant federal, state, and local environmental regulations.

Expansion joints, insulation, drainage layers, and overburden are not within the scope of this guide and therefore are not specifically addressed.

For design guidelines related to fully adhered hot-applied reinforced waterproofing systems, it is recommended to consult Guide C981.
