(Practice)Standard Practice for Application of Heat Weldable Atactic Polypropylene (APP) Modified Bituminous Waterproofing Membranes Systems for New Building Decks (Withdrawn 2015)
Standard Practice for Application of Heat Weldable Atactic Polypropylene (APP) Modified Bituminous Waterproofing Membranes Systems for New Building Decks (Withdrawn 2015)
SIGNIFICANCE AND USE
4.1 This practice provides general procedures, information, guidelines, and precautions for the application of heat welded modified bituminous waterproofing systems used as part of a new horizontal waterproofing system.
4.2 This practice is not all-inclusive and is intended only to supplement detailed instructions from designers and system manufacturers.
4.3 The horizontal (low sloped) deck or substrate referred to in this practice is reinforced cast-in-place structural concrete.
SCOPE
1.1 This practice covers the minimum application recommendations for heat weldable atactic polypropylene (APP) modified bituminous systems used as part of a new horizontal waterproofing system over occupied spaces of buildings where covered by a separate wearing course.
1.2 For the purpose of this practice, 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, protection boards, filter sheets, and the wearing surfaces are beyond the scope of this practice.
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.
WITHDRAWN RATIONALE
This practice covered the minimum application recommendations for heat weldable atactic polypropylene (APP) modified bituminous systems used as part of a new horizontal waterproofing system over occupied spaces of buildings where covered by a separate wearing course.
Formerly under the jurisdiction of Committee D08 on Roofing and Waterproofing, this practice was withdrawn in December 2015. This standard is being withdrawn without replacement due to its limited use by industry.
