ASTM D7693/D7693M-15 PDF Download

ASTM D7693/D7693M-15 is a standard guide that provides general procedures, information, guidelines, and precautions for the application of heat welded modified bituminous waterproofing systems on new concrete decks. The focus of this standard is on the installation of multi-ply Styrene Butadiene Styrene (SBS) and Atactic Polypropylene (APP) modified bituminous systems as part of a horizontal waterproofing system over occupied spaces of buildings, where a separate wearing course will be applied.

The guide emphasizes that it is not all-inclusive and should be used in conjunction with detailed instructions from designers and system manufacturers. The substrate for the application of the waterproofing system should be structurally sound, sloped to drain, capable of supporting the weight of the membrane and other system materials, and meet the relevant local building code requirements. The standard assumes that all components of the waterproofing system comply with applicable federal, state, and local environmental regulations.

It is important to note that this standard does not cover the installation of expansion joints, insulation, drainage layers, filter sheets, overburden, and wearing surfaces. These aspects are beyond the scope of the guide.
