A method for covering a site with synthetic turf, comprising the steps of: laying down a first elongate strip of synthetic turf, the first elongate strip having a first elongate side edge and a second elongate side edge opposite the first elongate side edge; laying down a second elongate strip of synthetic turf, the second elongate strip having a first elongate side edge and a second elongate side edge opposite the first elongate side edge, wherein the second elongate strip of synthetic turf is laid down substantially adjacent to the first elongate strip of synthetic turf in such a manner that a portion of the second elongate strip partially overlays a portion of the first elongate strip forming a lap joint; the synthetic turf comprises synthetic tufts (12, 22) extending from a top side of the turf, characterised: by applying heat to weld the first elongate strip of synthetic turf to the second elongate strip of synthetic turf along the lap joint; and in that the lap joint is formed by folding a portion of the second elongate strip over and onto itself such that the second elongate strip is laid down in such a manner that some synthetic tufts on the second elongate strip face downwardly and engage upwardly-facing tufts on the first elongate strip, whereby synthetic tufts on the first and second elongate strips enmesh with one another and as the heat is applied to the lap joint the synthetic tufts on the first and second elongate strips are welded to one another. laying down a first elongate strip of synthetic turf, the first elongate strip having a first elongate side edge and a second elongate side edge opposite the first elongate side edge; laying down a second elongate strip of synthetic turf, the second elongate strip having a first elongate side edge and a second elongate side edge opposite the first elongate side edge, wherein the second elongate strip of synthetic turf is laid down substantially adjacent to the first elongate strip of synthetic turf in such a manner that a portion of the second elongate strip partially overlays a portion of the first elongate strip forming a lap joint; the synthetic turf comprises synthetic tufts (12, 22) extending from a top side of the turf, characterised: by applying heat to weld the first elongate strip of synthetic turf to the second elongate strip of synthetic turf along the lap joint; and in that the lap joint is formed by folding a portion of the second elongate strip over and onto itself such that the second elongate strip is laid down in such a manner that some synthetic tufts on the second elongate strip face downwardly and engage upwardly-facing tufts on the first elongate strip, whereby synthetic tufts on the first and second elongate strips enmesh with one another and as the heat is applied to the lap joint the synthetic tufts on the first and second elongate strips are welded to one another. by applying heat to weld the first elongate strip of synthetic turf to the second elongate strip of synthetic turf along the lap joint; and in that the lap joint is formed by folding a portion of the second elongate strip over and onto itself such that the second elongate strip is laid down in such a manner that some synthetic tufts on the second elongate strip face downwardly and engage upwardly-facing tufts on the first elongate strip, whereby synthetic tufts on the first and second elongate strips enmesh with one another and as the heat is applied to the lap joint the synthetic tufts on the first and second elongate strips are welded to one another.
