ABSTRACT:
A facing panel is added to a surface of a geocell, on an outboard face of the cell, exposed to free water forces. The facing panel is filled with either stone, concrete, wooden boards, plastic sheets or steel sheets. In concrete usage, synthetic drainage is introduced to prevent the buildup of hydrostatic pressures behind the facing panel. The facing panel creates the ability to construct vertical retaining walls by stacking geocell units on top of each other and then filling a facing panel with either stone or concrete for a completed wall face. The geocell units are filled with sand or shell as retained in the geocells by geotextile liners. Circular geocells also retain fill in a geotechnical structure. Circular compartments are formed by connecting plastic mesh material at points on the compartment circumference, thus producing a cylindrical confinement of granular fill. The geotechnical structure thus formed may be used in a variety of applications such as bulkheads, vertical walls, wave breaks, the side of an artificial island, confinement berms, and columns to support vertical loads.
