Designation:D801417Standard Guide forSelection of Membranes Used in Vegetative RoofingSystems1This standard is issued under the fixed designation D8014;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 The purpose of this guide is to provide guidance in theselection of a suitable waterproofing membrane within avegetative roof system.The guide offers various options forreviewing the membrane installation during and upon comple-tion of the installation and prior to the vegetative componentsbeing installed.This guide applies to membranes that do or donot require UV protection.For the purpose of this guide,thesupporting structure and roof deck are assumed to be mechani-cally and structurally sound and will accept the weight of thevegetative roof system including the membrane,insulation,andother roofing/waterproofing components including all compo-nents related to the vegetative layers as well as the requireddesign loads.Slope to drain at the membrane level is preferredand should be included where possible.Providing a replace-ment or a re-cover vegetative roofing system on an existingbuilding may require that the support structure be reinforced sothat it can safely support the additional weight of the vegetativeroof system and also provide the minimum live load capacityrequired by the building code.1.2 Design criteria associated with the vegetative portionsof the system are beyond the scope of this guide.Please referto Guide E2777.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1079 Terminology Relating to Roofing and WaterproofingD5957 Guide for Flood Testing Horizontal WaterproofingInstallationsD7877 Guide for Electronic Methods for Detecting andLocating Leaks in Waterproof MembranesE2777 Guide for Vegetative(Green)Roof Systems2.2 ANSI/SPRI Standards:3ANSI/SPRI VR-1 Procedure for Investigating Resistance toRoot Penetration on Vegetative Roofs2.3 Other Standards and Documents:FLL Guidelines for the Planning,Construction and Mainte-nance of Green Roofing Green Roofing Guideline Sec-tion 6.3 Protection Against Damage to the Waterproofing/Root-resistant Membranes FLL Procedure for Investigat-ing Resistance to Root Penetration of Roof Membranesand Protective Layers for Green Roofing43.Terminology3.1 DefinitionsFor definitions of terms used in this guide,see Terminology D1079.4.Significance and Use4.1 Thisguideprovidesthegeneralinformation,procedures,and guidelines for the selection of the waterproof-ing membrane to create a waterproofing system for a Vegeta-tive(Green)roof.4.2 This guide is not all inclusive;this guide is intended tosupplement detailed instructions from manufacturers,ASTMStandards,and building code requirements.5.Roof Design Classifications5.1 Types of Constructions or Applications:1This guide is under the jurisdiction of ASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.24 on Sustain-ability.Current edition approved July 15,2017.Published August 2017.DOI:10.1520/D8014-17.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.4Available from Forschungsgesellschaft Landschaftsentwicklung Landschafts-bau e.V.(FLL),Friedensplatz 4,53111 Bonn,Germany,www.fll.de.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 5.1.1 NewA vegetative roof can be integrated with theother building elements during construction.All new compo-nents are used to construct the roofing/waterproofing system.Performance and service requirements of the vegetated roof areaddressed in the b
