Abstract: A method of joining overlapping thermoplastic geomembrane components in which a first thermoplastic geomembrane component and a second thermoplastic geomembrane component are positioned in overlapping relationship between a pair of complementary molding surfaces, with one or more of the complementary molding surfaces being defined by an electrically conductive metal susceptor. Heat is generated in the metal susceptor and transferred by thermal conduction from the metal susceptor to overlapping portions of the first and second thermoplastic geomembrane components to locally melt and coalesce a portion or more of the thermoplastic material of the first thermoplastic geomembrane component and a portion or more of the thermoplastic material of the second thermoplastic geomembrane component. The molten thermoplastic material of the first and second thermoplastic geomembrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint.

Abstract: A membrane pulling device includes an elongate frame and a lever coupled with the elongate frame at a fixed position joint. The fixed position joint is positioned within a middle section of the elongate frame. A plurality of step plates are attached to the elongate frame, including a back step plate and one or more front step plates. A forward fairlead is coupled with the elongate frame and includes two pulley wheels. Side arms may pivot out from the elongate frame to assist in use of the membrane pulling device when pulling a membrane at an angle to the orientation of the device, such as adjacent to a parapet wall.
