Manufactured composite having synthetic vegetation and impermeable geomembrane, and capping system using same

A capping system used for covering foundation soil of a job site, the system comprising:

• a plurality of pieces of pre-manufactured composite physically and permanently joined to one another, said composite comprising:
• a synthetic turf including synthetic grass and 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 and wherein the untufted section extends from the tufted section to a first length-wise edge of the permeable primary;
• an impermeable geomembrane having a first side and a second side and underlying the second side of the permeable primary of the tufted and untufted sections of the synthetic turf;
• a first layer of bonding material in contact with the second side of the permeable primary and the first side of the impermeable geomembrane, wherein the bonding material adjoins the synthetic turf and the impermeable geomembrane such that the synthetic turf and the impermeable geomembrane are permanently merged and bonded together;
• a second layer of bonding material on the first side of the permeable primary along a length of the untufted section of the synthetic turf between the tufted section and the first length-wise edge of the permeable primary;
• a splicing tape on the second layer of bonding material along the length of the untufted section, wherein a width of the splicing tape is substantially less than a width of the untufted section and wherein the splicing tape is offset from the length-wise edge of the permeable primary such that a space is provided between the splicing tape and the first length-wise edge of the permeable primary;
• and
• a plurality of anchoring devices each extending through the untufted section at a location within the space between the splicing tape and the first length-wise edge of the permeable primary.
