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.

Abstract: A jacket for protecting rope, cable, chain or other connecting means used to interconnect blocks, grids or other forms in a revetment structure. The protective jacket comprises tubing which extends in substantially continuous form through the revetment structure and surrounds the connecting means and protects it from abrasion, as well as from degradation and deterioration caused by contact with water, salt sand, ice, sunlight and ultraviolet light, and other components of the environment.

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.

Abstract: A cellular precast grid and mat for use as revetment. The grid, which may typically be cast of concrete, is substantially rectangular, having a flat bottom and, in its middle, two optional vertical openings of rectangular cross section with two inwardly sloping sides. The grid also has two vertical U-shaped channels on each longer opposed side and a two-tier vertical channel on each shorter opposed side, which vertical channel can accept projecting portions of the shorter side of two like grids positioned in abutting relationship, thereby permitting arrangement of grids into revetment of abutting staggered interlocking rows of grids. The grids may be individually placed with or without interconnecting pins or may be interconnected into mats by passing cables through tunnels passing horizontally through the grids parallel to the longer sides.
