ABSTRACT:
A drainage element is constructed of loose fill elements within a container of mesh construction. The loose fill elements are disposed in unconnected relation to each other so as to be able to migrate within the container. The openings of the mesh container allow water to pass through while retaining the loose fill elements in place.
