Significance and Use

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.

1. 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 and health practices and determine the applicability of regulatory limitations prior to use.
