During installation of composite pieces at a job site, an edge portion of a tufted section of a second composite piece is overlaid onto an edge untufted section of the first composite piece already laid and anchored over foundation soil to form a reinforced overlapping seam, through which the two composite pieces are physically and permanently joined together. As composite pieces are joined together, the continuity of synthetic grass and the continuity of impermeability are extended and realized over the entire site to form permanent, impermeable and functional aesthetic cover for a job site. ## Claims ### Claim 1 A synthetic turf composite structure, comprising: 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;
