Prefabricated vertical drain designed Verti-Drain is applied to reduce construction time and speed up the consolidation of soft ground. Top menu. Main menu. left menu. Verti-Drain ® Verti-Drain. In some instances, prefabricated drainage strips that are horizontally positioned over the tops of the PVDs can be used instead of a sand blanket. Design. Although vertical sand drains are still used (and are actually preferred in some instances), PVDs have generally replaced vertical sand drains.

This paper shows the development of an approximate analytical solution of radial consolidation by prefabricated vertical drains with a threshold gradient. To understand the effect of the threshold gradient on consolidation, a parametric analysis was performed using the present solution.
The applicability of the present solution was demonstrated in two cases, wherein the comparisons with Hansbo Cited by: 3. 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.
