Abstract
Abstract A revetment panel for installation along embankments and other earthen structures, including structures partially or fully covered by water, which utilizes a fabric web having a plurality of compartments separated by selvage. The web is formed of two fabric layers, which are woven separately on the same loom to form the compartments, and interwoven to form the selvage. The fabric layers are separately woven to form slots in the selvage which allow cables to pass through the web, and which allow filler material to flow between compartments during filling. The web is transported to its installation site, and placed. The compartments in the web are then inflated with the filler material, which may be cementitious slurry or mortar consisting in part of sand and gravel found near the installation site, or simply a mixture of sand, gravel, and water. The resulting matrix of forms interconnected by fabric and cable provides a durable, economical and flexible erosion control layer. Later, the fabric may wear away leaving a highly articulable mat of hardened forms interconnected by cable or other connecting means.
