Significance and Use
4.1 This guide provides general procedures, information, guidelines, and precautions for the application of heat welded modified bituminous waterproofing systems used as part of a horizontal waterproofing system.
4.2 This guide is not all-inclusive and is intended only to supplement detailed instructions from designers and system manufacturers.
4.3 The horizontal deck or substrate referred to in this guide is reinforced cast-in-place structural concrete.
1.1 This guide presents application recommendations for the heat welding installation of multi-ply Styrene Butadiene Styrene (SBS) and Atactic Polypropylene (APP) modified bituminous systems to new, reinforced, cast in place structural concrete used as part of a horizontal waterproofing system over occupied spaces of buildings where covered by a separate wearing course.
1.2 For the purpose of this guide, the substrate shall be structurally sound, sloped to drain, able to accept the weight of the membrane and other system materials, and meet the local building code requirements. Similarly, all components of the waterproofing system are assumed to comply with any federal, state, and local environmental regulations that may be in effect at the time of installation. Expansion joints, insulation, drainage layers, filter sheets, overburden, and the wearing surfaces are beyond the scope of this guide.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
