About This Item
ASTM C1471/C1471M is the ASTM standard guide for the use of high solids content cold liquid-applied elastomeric waterproofing membrane on vertical surfaces. It helps define a consistent technical basis for selecting and using this type of waterproofing system where vertical applications require dependable membrane performance. By focusing on application guidance rather than broad theory, the standard supports better product evaluation, installation planning, and communication between specifiers, contractors, and purchasers.
Purpose of ASTM C1471/C1471M
The purpose of this guide is to provide practical direction for the use of a high solids content, cold liquid-applied elastomeric waterproofing membrane on vertical surfaces. ASTM C1471/C1471M is intended to support informed decision-making around material use, application conditions, and expected performance considerations within the limits of the standard’s scope. For project teams, it can serve as a reference point when reviewing specifications, comparing products, or setting quality expectations for membrane applications on vertical substrates.
Common use cases of ASTM C1471/C1471M
This guide is commonly used when a project calls for a liquid-applied waterproofing membrane on vertical surfaces and a consistent ASTM reference is needed for product selection or specification writing. It is relevant to professionals evaluating cold-applied elastomeric systems that are designed to form a waterproof barrier after application. ASTM C1471/C1471M may also be useful during procurement, submittal review, and field coordination when teams need a shared technical basis for membrane use on vertical assemblies.
Why ASTM C1471/C1471M matters
ASTM C1471/C1471M matters because it helps bring consistency to how this waterproofing membrane type is understood and applied in practice. A clear ASTM guide can reduce ambiguity in technical requirements, support more reliable product comparison, and improve communication across design, purchasing, and installation workflows. For owners and contractors, it can also help strengthen quality control and reduce the risk of selecting a membrane system that is not suited to the intended vertical application.
