    摘要: A liner is disclosed for a waterway of the type adapted to overlie the bottom of the waterway while a cementious layer covers and protects the liner. The liner itself is positioned at the bottom of the waterway by a machine having two elongated and spaced apart guide rails, each having a hollow interior and a longitudinally extending slot open at each end. The liner includes an elongated, flexible and water impervious sheet of a geomembrane material, such as polyvinyl chloride (PVC) or polyethylene material, having two spaced apart side edges. A strand is secured along each edge of the sheet by wrapping a flap of the sheet around the strand so that the flap encircles and then flatly abuts against one side of the sheet. A heat seal between the flap and the sheet bonds the flap and sheet together and the enclosed strand is then longitudinally slidably positioned within the interior of one of the guide rails.
