Wedge-weldable manufactured composite having synthetic vegetation and impermeable geomembrane

A job site, comprising:

• an area of land having an exposed surface;
• and
• a plurality of pieces of synthetic turf composite structure arranged in a side-by-side manner covering at least a portion of the exposed surface of the area of land, wherein each one of the pieces of synthetic turf composite structure comprises:
• a synthetic turf including synthetic grass and a permeable primary, wherein the synthetic turf includes a tufted section having the synthetic grass tufted into the permeable primary and an untufted section without the synthetic grass tufted into the permeable primary, wherein an upper end portion of the synthetic grass extends above a first side of the permeable primary and a lower end portion of the synthetic grass extends through the permeable primary to expose the lower end portion of the synthetic grass at a second side of the permeable primary, wherein the untufted section extends from the tufted section to a first edge of the permeable primary and wherein an overall width of the permeable primary defines an overall width of the synthetic turf composite structure;
• an impermeable geomembrane having an upper side and a lower side, wherein the impermeable geomembrane underlies the second side of the permeable primary at said tufted and untufted sections thereof, wherein the lower end portion of the synthetic grass terminates within a space defined between the upper side of the impermeable geomembrane and the second side of the permeable primary;
• and
• a first layer of bonding material between the permeable primary of the synthetic turf and the impermeable geomembrane adjoining the tufted and untufted sections of the synthetic turf with the impermeable geomembrane such that the synthetic turf and the impermeable geomembrane are bonded together to form a composite structure, wherein the first layer of bonding material adjoins a first width of the permeable primary less than the overall width of the synthetic turf composite structure to the impermeable geomembrane whereby a second width of the permeable primary is un-adjoined from the impermeable geomembrane thereby defining an unbound edge section of the synthetic turf.

A method of making a synthetic turf composite structure used for covering foundation soil of a job site, the method comprising:

• providing a synthetic turf including synthetic grass and a permeable primary, wherein the synthetic turf includes a tufted section having the synthetic grass tufted into the permeable primary and an untufted section without the synthetic grass tufted into the permeable primary, wherein an upper end portion of the synthetic grass extends above a first side of the permeable primary and a lower end portion of the synthetic grass extends through the permeable primary to expose the lower end portion of the synthetic grass at a second side of the permeable primary, wherein the untufted section extends from the tufted section to a first edge of the permeable primary and wherein an overall width of the permeable primary defines an overall width of the synthetic turf composite structure;
• providing an impermeable geomembrane having an upper side and a lower side, wherein the impermeable geomembrane underlies the second side of the permeable primary at said tufted and untufted sections thereof, wherein the impermeable geomembrane extends across at least a portion of a first width of the synthetic turf composite structure and wherein the lower end portion of the synthetic grass terminates within a space defined between the upper side of the impermeable geomembrane and the second side of the permeable primary;
• and
• adjoining a first width of the permeable primary less than the overall width of the synthetic turf composite structure to the impermeable geomembrane with a first layer of bonding material between the permeable primary and the impermeable geomembrane whereby the synthetic turf and the impermeable geomembrane are bonded together to form a composite structure and whereby a second width of the permeable primary is un-adjoined from the impermeable geomembrane thereby defining an unbound edge section of the synthetic turf.
