ABSTRACT:
An elasticized geosynthetic panel, geofoam composition and method operable for permitting controlled deformation of earth materials adjacent a rigid earth retaining structure or the like. The panel includes a drainage component. a water and gas membrane and a compressible geofoam member. The compressible geofoam member is elasticized and exhibits a cross-anisotrophic characteristic which has enhanced elasticity in a direction normal to the geosynthetic panel.
