1. Scope
1.1 This guide lists test methods intended to establish a minimum level of acceptable performance attributes for rein- forced or laminated waterproofing membranes applied to below-grade walls. 1.2 This guide does not include cementitious, integral, or bentonite waterproofing systems. 1.3 This guide does not include membranes applied under slabs on grade or on suspended slabs below grade or applied to soil retaining systems, water containment structures, or tun- nels. 1.4 It is not possible to establish a precise correlation between laboratory tests on waterproofing membranes and performance attributes after installation due to variations in chemicals in the soil, design, material, and installation. 1.5 The values stated in either inch-pound or SI 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 nonconformance with the standard. 1.6 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 appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.7 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 For definitions relating to waterproofing, refer to Termi- nology D1079. 3.2 Definitions ofTerms Specific to This Standard: 3.2.1 perform—the ability of all essential properties to meet or exceed specified test values. 3.2.2 protection course—prefabricated boards, drainage composites, sheets, or insulation applied to the positive surface of the membrane to protect it from damage from backfilling and construction operations. 3.2.3 waterproofing membrane—a single or multiple-ply membrane, factory manufactured or liquid applied and which is internally reinforced or laminated to a plastic sheet. It is intended to prevent the passage of liquid water under continu- ous or intermittent hydrostatic, dynamic, or static pressure. The membrane is fully or partially attached, and is applied to the positive or wet side of a vertical substrate below-grade.
4. Significance and Use
4.1 A waterproofing membrane should maintain its water- tight integrity for the life of the building in a continuously or intermittently moist environment and may be subject to con- tinuous or intermittent hydrostatic pressure. It should resist chemicals that can harm the membrane and root growth. This guide lists minimum performance attributes required of water- proofing membranes applied to below-grade walls. Products not previously used as waterproofing membrane materials require additional tests beyond the scope of this guide. This guide is not intended for use on in-service waterproofing materials. Waterproofing membranes and other components should conform to ASTM product standards, if available.4.2 Limitations—Prior to use and in service, waterproofing may be exposed to a variety of conditions so no one test will provide evaluations related to performance for all exposures. Neither will all tests be necessary in all evaluations for specific exposures.
5. Waterproofing Membrane Classifications
5.1 Type ofMaterial: 5.1.1 Type I—Bituminous. 5.1.1.1 Grade 1—Single or multiple ply adhered. 5.1.1.2 Grade 2—Liquid-applied. 5.1.2 Type II—Non-bituminous organic. 5.1.2.1 Grade 1—Single ply. (1) Class 1—Adhered sheet. (2) Class 2—Partially attached sheet. 5.1.2.2 Grade 2—Liquid-applied (polyurethane, polymethyl methacrylic, polyester, polyether).
6. Waterproofing Membrane Performance Attributes
6.1 The following general attributes are required for a waterproofing membrane: 6.1.1 Perform under continuously moist conditions and alternate wetting and drying. 6.1.2 Perform under hydrostatic pressure. 6.1.3 Resist acids, alkalis, and other chemicals including such as those commonly contained in fertilizers and soil poisoners. 6.1.4 Resist fungus and bacteria in soils. 6.1.5 Possess low water absorption. 6.1.6 Resist puncture for membranes that lack a protection course. 6.1.7 Possess a moderate degree ofelongation and elasticity. 6.1.8 Possess sufficient flexibility to enable unrolling or curing properly without failure. (Not required for Type I, Grade 1 or Type II, Grade 2.) 6.1.9 Possess crack-bridging capabilities. 6.1.10 Adhere tenaciously to the substrate.
