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. The compartments are staggered in relation to each other and separated by selvage. The web is formed of two fabric layers, which are woven separately to form the compartments and fastened together to form selvage separating them. Slots are formed in the selvage which allow cables to pass longitudinally through the web and interlock the compartments, 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 cementitous slurry or mortar consisting in part of sand and gravel found near the installation site, or simply a mixture of sand, gravel, and water or other ingredients. 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 and interlocked by longitudinal cables or other connecting means.
