About This Item
ASTM D2643/D2643M is the ASTM standard for a prefabricated bituminous geomembrane used as a canal and ditch liner in exposed applications. It provides a technical basis for describing and evaluating this liner product so buyers, engineers, and suppliers can compare materials more consistently. Because canal and ditch lining projects depend on dependable performance and installation suitability, the standard helps support clearer procurement, quality control, and compliance decisions.
What is ASTM D2643/D2643M?
This standard is a product specification focused on prefabricated bituminous geomembrane intended for use as an exposed canal and ditch liner. In practical terms, ASTM D2643/D2643M sets a common reference for the material type, rather than a broad design guide for every lining system. That makes it useful when evaluating whether a geomembrane product is suitable for this specific service environment and when documenting requirements for manufacturing, testing, and acceptance.
Where is ASTM D2643/D2643M used?
ASTM D2643/D2643M is commonly used in water conveyance and earthwork projects where canals or ditches require a prefabricated bituminous lining that remains exposed. It is relevant to project specifications, material submittals, and purchase documents for liner products intended for these applications. The standard is especially useful when teams need a clear technical reference for selecting and verifying a geomembrane that is meant to function as a surface-exposed liner rather than a buried membrane.
Why is ASTM D2643/D2643M important?
This specification matters because it supports consistency in product evaluation and helps reduce uncertainty during procurement and quality control. ASTM D2643/D2643M gives manufacturers and purchasers a shared framework for identifying the expected characteristics of the liner product. That can improve specification writing, simplify comparisons between suppliers, and help users confirm that the selected material aligns with the intended canal or ditch lining application. It is also useful for compliance-oriented documentation and technical review.
