Scope 1.1 The purpose of this document is to provide guidance in the selection of a suitable waterproofing membrane within a vegetative roof system. The Guide will offer various options for reviewing the membrane installation for quality assurance and quality control during and upon completion of the installation and prior to the vegetative components being installed. The membrane may be the type that is UV stable or requires a protection layer from UV exposure. 1.2For the purpose of this guide, the structure and deck are assumed to be mechanically and structurally sound, provide slope to drain and to accept the weight of the vegetative roof system including the membrane, insulation, and other roofing/waterproofing components including all components related to the vegetative layers as well as the required design loads. 1.3 Design criteria associated with the vegetative portions of the system are beyond the scope of this guide. Please refer to ASTM E2777 Standard Guide for Vegetative (Green) Roofing Systems 1.4This 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 application of regulatory limitations prior to use.
This Standard will assist designers and specifiers as to the type of waterproofing membrane they may choose for given applications
