1.1 本指南涵盖了作为钠膨润土复合材料生产的防水膜的一般安装指南，该复合材料包含在两个互锁的针刺土工布中，供设计人员在制定项目特定图纸和规范时考虑。本指南涵盖了将防水应用于地下现浇混凝土基础墙的正面、回填和开挖支撑（SOE）施工以及混凝土压力板下方的施工应用。 本指南不包括广场桥面施工应用，无论是拼合板施工或底座上的摊铺机，还是植草绿色屋顶防水应用。 1.2 本指南不包括使用波纹纸载体生产的钠基膨润土防水膜、与土工膜结合的膨润土和喷涂膨润土系统。 1.3 在本指南中，假设混凝土为现浇混凝土，表面轮廓如指南中所建议 D5295/D5295M 根据ACI 309中的适用指南合并，结构良好，能够承受预期荷载的重量，并符合当地建筑规范要求。 假设防水系统的所有组件均符合安装时可能生效的任何联邦、州和地方环境法规。伸缩缝、保温层和排水层不在本指南的范围内。 1.4 本指南不包括安装在用砌体材料、预制混凝土或气动混凝土（即喷射混凝土）建造的地下基础墙和板上的钠膨润土土工布膜。 1.5 以国际单位制表示的数值应视为标准值。 括号中给出的单位值仅供参考。 1.6 不同的钠基膨润土土工布膜具有不同的组成和结构材料，这会影响物理性能。因此，本指南中包含的程序可能不适用于所有现场条件下的所有钠基膨润土土土工布膜。 1.7 本指南无意分配质量保证或质量控制的责任。具体的质量保证和质量控制项目应在项目规范和合同文件中说明。 1.8 本指南无意包括与防水材料或安装相关的保修要求。 1.9 本指南并不旨在包括解决施工项目中可能遇到的各种条件的所有详细技术。 1.10 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.11 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ===意义和用途====== 5.1 本指南概述了钠膨润土针刺土工布防水系统应用的一般安装程序和注意事项。 5.2 本指南并非包罗万象，仅用于补充设计师的详细图纸和规范以及制造商的安装指南。本指南所述某些系统的制造商需要本指南中未描述的专有产品和特殊程序。因此，在应用本指南时，应考虑适用于项目中遇到的每个现场施工条件的制造商指南和细节。

1.1 This guide covers general installation guidelines of waterproofing membranes produced as a composite of sodium bentonite contained within two interlocked needle-punched geotextiles for designers to consider when developing project-specific drawings and specifications. This guide covers construction applications where the waterproofing is applied to the positive side of below-grade cast-in-place concrete foundation walls, both backfilled and support of excavation (SOE) construction, and under concrete pressure slabs. This guide does not cover plaza deck construction applications, either split-slab construction or pavers on pedestals, or vegetated green roof waterproofing applications. 1.2 This guide does not cover sodium bentonite waterproofing membranes produced with a corrugation paper carrier, bentonite bonded to a geomembrane, and spray-applied bentonite systems. 1.3 For the purpose of this guide, concrete is assumed to be cast-in-place with a surface profile as recommended in Guide D5295/D5295M , consolidated in accordance with applicable guidelines in ACI 309, structurally sound, able to accept the weight of anticipated loads, and meets the local building code requirements. 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, and drainage layers are beyond the scope of this guide. 1.4 This guide does not cover sodium bentonite geotextile membranes installed on below-grade foundation walls and slabs constructed with masonry materials, precast concrete, or pneumatically applied concrete (that is, shotcrete). 1.5 The values stated in SI units are to be regarded as standard. The unit values given in parentheses are for reference information only. 1.6 Different sodium bentonite geotextile membranes have different materials of composition and construction which can affect physical properties. The procedures contained in this guide, therefore, may not be universally applicable to all sodium bentonite geotextile membranes under all field conditions. 1.7 This guide does not purport to assign responsibilities of quality assurance or quality control. Specific quality assurance and quality control items should be addressed in project specifications and contract documents. 1.8 This guide does not purport to include requirements for warranties associated with the waterproofing materials or installation. 1.9 This guide does not purport to include all detailing techniques to address various conditions that can be encountered on construction projects. 1.10 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This guide outlines general installation procedures and precautions for the application of sodium bentonite needle-punched geotextile waterproofing systems. 5.2 This guide is not all inclusive and is intended only to supplement detailed drawings and specifications from designers and the installation guidelines of manufacturers. Manufacturers of some of the systems addressed by this guide require proprietary products and special procedures not described in this guide. Manufacturers’ guidelines and details applicable for each site construction condition encountered on a project should therefore be considered in the application of this guide.
