Prefabricated Vertical Drain Test Standard Being Developed by Geosynthetics Committee

ASTM International Committee D35 on Geosynthetics is currently developing a proposed new standard that covers the test procedure for evaluating the effectiveness of prefabricated vertical drains to enhance the consolidation of soils under specified conditions. The proposed standard, WK13402, Test Method for Large Scale Consolidation Test for Prefabricated Vertical Drains, is under the jurisdiction of Subcommittee D35.03 on Permeability and Filtration.

“For geotechnical engineers that are very familiar with sand drains as a means of accelerating consolidation of soft foundation soils, WK13402 will provide a means of evaluating how prefabricated vertical drains perform in relation to a sand drain,” says L. David Suits, a member of the task group developing the standard and executive director, North American Geosynthetics Society. Suits notes that the proposed standard will be most useful to engineers who are designing structures or embankments over soft foundation walls. //
