Abstract:
A method for forming a geomembrane liner testable for leaks by securing adjacent panels together with the conductivity of the lower surface of an overlying panel broken along a line adjacent the panel overlapping edge, and the overlapping edges sealed along the line. A heat welder has slots for the overlapping panel edges, with a heated wedge between the slots and having a projection to break the conductivity of the overlying panel bottom surface as it passes the wedge. The slots merge to press the liner edges together to heat weld them along the line of broken conductivity as the welder is moved along the panel edges.

Claim (Index 8):
A heat welder for securing edges of adjacent geomembrane liner panels together, said geomembrane liner panels having conductive bottom surfaces and being overlapped along their edges with a first one of said panels on top of a second one of said panels, said welder comprising:\n a welder body having forward and rear ends and defining horizontally oriented first and second slots with top and bottom walls extending between the welder body front and rear, wherein\n the first slot is open on one lateral side for receiving the first one of said panels, \n the second slot is below said first slot and open on the lateral side opposite the one side for receiving the overlapping edge of the second one of said panels, and \n said first and second slots merge at the body rear end; \n a drive for moving the welder body forward; a heating unit between said first and second slots and forward of said merged first and second slots, said heating unit defining a portion of a bottom wall of the first slot; and at least one projection extending partially into said first slot for engaging the conductive bottom surface of the first one of said panels to melt through the conductive bottom surface along a line as it passes the projection; wherein said merged first and second slots press together first and second liner panels to heat weld the first and second liner panels together along the line of the interrupted conductive bottom surface.
