WSRCA Informational & Alert Bulletin 2018-1W: Changes in ASTM Waterproofing Standards May Affect Member Contractors

If an ASTM standard is referenced in a project specification, the contractor under contract for that work is typically required to comply with the requirements of the standard.

Relatively significant developments within the industry’s waterproofing standards may potentially affect Western States Roofing Contractors Association (WSRCA) Member Contractors, as well as Member Designers of waterproofing systems, and perhaps some of our Manufacturer Members. Over the last decade or so ASTM’s Waterproofing Subcommittee D08.22 has made some rather significant advances in publishing several new standards. ASTM has also made changes to a number of existing waterproofing and waterproofing-related standards.

WSRCA members should be aware that if an ASTM standard is referenced in a project specification, the contractor under contract for that work is typically required to comply with the requirements of the standard. It is also important to note that if current or future codes governing a project reference an ASTM standard the design, materials, applications, and testing is to comply with the requirements of that standard. If an ASTM standard is referenced in the documents governing your project you are accountable for knowing the standard and performing construction according to the requirements of the referenced standard(s).

Some of the new standards, and changes to existing standards, if referenced by project documents or amended into your state or locally adopted code, could impact waterproofing contractors in ways that not everyone may be aware.
