Abstract: Wall systems are disclosed which employ a plurality of individual panels formed of extruded polymeric material joined in edge-to-edge relation including wale members which are vertically offset and interlocked at end portions thereof with adjacent wale members. The wall systems include connector elements for joining and interlocking the adjacent panel edges, and panels are disclosed, each having a continuous convex surface between their opposite side edges and strengthening ribs formed on a concave surface disposed opposite the convex surface thereof. A revetment system is disclosed in which a pair of wall sections are positioned in facing spaced-apart relation and joined by tie bolts extending through the wale members, to receive concrete therebetween.

Abstract: A substantially flat layer of material and method and apparatus for making the same, as well as a product utilizing the same, are provided, the flat layer of material having opposed substantially parallel spaced apart flat surfaces and comprising polymeric material and reinforcing particles disposed in the polymeric material and having at least a part thereof with the long dimensions thereof oriented so as to be substantially perpendicular to the opposed surfaces thereof.

Abstract: The apparatus has a pair of electrodes that create an electrostatic field therebetween which orients at least part of the reinforcing particles in a liquid polymeric layer so that the long dimensions of the part of the particles are disposed substantially perpendicular to the opposed flat surfaces of the layer of material, the electrodes each have a portion disposed upstream of a heating tunnel and another portion disposed in the tunnel so that the oriented particles are held in the oriented condition thereof as the heating tunnel dries the polymeric material.

Abstract: A method and apparatus for making a polymeric coated fabric layer is provided, the method comprising the steps of providing a fabric layer having warps and fills initially woven at a certain angle relative to each other, then changing the certain angle to another angle by stretching the fabric layer in one direction thereof whereby the fabric layer is in an altered condition thereof, disposing a liquid polymeric coating on at least one side of the fabric layer while the same is in the altered condition, doctoring the coating, further stretching the fabric layer in the one direction after the step of disposing the coating thereon, and drying the coating with a heating unit to at least a degree thereof that will hold the fabric layer in substantially the altered condition thereof, the step of doctoring the coating taking place after the step of further stretching the fabric layer and the step of further stretching the fabric layer taking place after the heating unit has dried the coating to at least a degree th

Abstract: A method and apparatus for making a polymeric coated layer is provided, the method comprising the steps of providing a strand layer with the strands thereof disposed in a predetermined pattern, forming the strand layer to comprise a first substantially planar layer of strands disposed in superimposed relation with a second substantially planar layer of strands whereby the strands of the first layer are not woven with the strands of the second layer, disposing a liquid polymeric coating on the strand layer while the strands thereof are disposed in the pattern thereof, doctoring the coating, stretching the strand layer in one direction after the step of disposing the coating thereon, and drying the coating with a heating unit to at least a degree thereof that will hold the strands of the strand layer in substantially the pattern thereof whereby the coating effectively is the sole securement securing the strands of the first layer to the strands of the second layer and thereby imparts its flexible characteristic
