Abstract

It has long been the opinion of many engineers that the primary cause of failure in certain coastal structures is due to an inadequate filter system. Normally, filters for granular soils are made up of layers of graded sand, gravel and stone materials in various combinations and thickness dimensions. Very often these materials are expensive and in some cases, due to geographic location, are unavailable. Even if the required materials are easily accessible, proper placement is tedious and demands strict supervision. This paper discusses the use of "plastic filters" as a replacement for graded filter systems and filter blankets in coastal structures. While this discussion and illustrations are limited to coastal structures, plastic filters can and have been used in river, lake, canal, dam and other hydraulic structures.
