1.1 This practice covers the minimum application recommendations for styrene butadiene styrene (SBS) modified bituminous systems used as part of a new horizontal waterproofing system over occupied spaces of buildings when 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 SI units are to be regarded as the standard. The values given in parentheses are for information only. 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.
