Standard Guide for Selection of Test Methods for Prefabricated Vertical Drains (PVD)
Standard Guide for Selection of Test Methods for Prefabricated Vertical Drains (PVD)
SIGNIFICANCE AND USE 4.1 To properly evaluate prefabricated vertical drains, tests must be performed according to specific test methods and procedures. Failure to follow this practice can result in data not representative of the product's characteristics and performance. SCOPE 1.1 This guide provides recommendations for the selection of appropriate test methods for prefabricated vertical geocomposite drains (sometimes referred to as wick drains) used in geotechnical engineering applications to provide consistency in data reporting. 1.2 This guide includes test methods for all types of prefabricated geocomposite drains manufactured in a plant and consisting of a polymeric core structure with a synthetic fabric (geotextile) jacket for filtration. 1.3 This guide is intended to aid all personnel involved in the selection, manufacture, installation, or evaluation of prefabricated vertical drains. 1.4 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. 1.5 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.
ASTM D6917-16(2022): Standard Guide for Selection of Test Methods for Prefabricated Vertical Drains (PVD) provides comprehensive recommendations for evaluating prefabricated vertical geocomposite drains, often referred to as wick drains. Developed by ASTM International, this guide supports engineers, manufacturers, and all stakeholders in geotechnical engineering by helping standardize the methods used to characterize and assess PVDs. By following this standard, users can assure consistency in data reporting and informed product selection, installation, and evaluation of prefabricated vertical drains.
Prefabricated vertical drains play a critical role in soil consolidation projects by accelerating the drainage of excess pore water, thus improving ground stability for various construction activities. This guide ensures the test methods selected are appropriate for the diverse types of geocomposite drains currently available.
Prefabricated vertical drains are widely used in geotechnical engineering applications to improve soil stability and accelerate consolidation in soft soils, such as those found in embankment construction, land reclamation, and ground improvement projects. By referencing ASTM D6917-16(2022), engineers and project managers can:

ASTM D6917-16(2022) references a suite of important ASTM test methods and practices relevant to the performance and characterization of geosynthetics and geocomposites, including:
These referenced standards facilitate the accurate measurement of critical properties such as transmissivity, filter performance, seam strength, and durability, supporting the core objective of reliable performance assessment for PVDs in geotechnical projects.
By adopting ASTM D6917-16(2022), organizations benefit from a unified framework for the selection of test methods for prefabricated vertical drains. This provides greater confidence in product evaluation, supports project success in ground improvement, and aligns with internationally recognized principles of standardization. For stakeholders in construction, civil engineering, and infrastructure development, this standard acts as an essential reference to optimize soil improvement practices and ensure long-term stability.
