that they are resistant to mildew aging and abrasion so they will therefore maintain the positions of the surrounding stones 32 furthermore the synthetic resins 34 are virtually nonbiodegradable such that the user will not be concerned with repeating the steps of dispensing the synthetic resin 34 in the central core 28 after a period of time additionally the block elements 20 described herein may be produced in a block molding machine not illustrated as is well known preferably the mold not illustrated is loaded with a selected mix of concrete or cement and the mixture is set to form two block elements 20 simultaneously in a u201c siamese u201d pattern once the mixture has formed and cured the block elements 20 may be split along the joined major faces 22 to form two trapezoidal split face block elements 20 likewise the block elements 20 may be formed from suitable plastic materials such as abs or pvc by extrusion or molding decorative aluminum castings suitable for use as block elements 20 may be made by the lost foam casting method as is well known it should further be noted that the positive connection created through the use of the anchoring stones 32 synthetic resin 34 and mesh grid 9 reduces problems commonly found in conventional retaining walls for example.
