Abstract

Conventionally prefabricated vertical drain (PVD) consists of a core and a filter sleeve as two separable components. A new type of PVD is now available in which the filter and the core are bound together by heat melting to become an integrated body. This new type of integrated PVD has offered a new method in improving the properties and performance of PVD. Laboratory test results are presented in this note to show that both the tensile strength and the discharge capacity of the integrated PVD have increased as compared with those of the separable type of the same materials.
