Method and Apparatus for Forming Leak Detectable Geomembrane Liners

摘要

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.

1. A method of forming a geomembrane liner testable for leaks, comprising:
providing a plurality of geomembrane panels having conductive lower surfaces; securing adjacent panels together, wherein the edge of one of the adjacent panels overlaps an underlying edge of the other of the adjacent panels, the conductivity of the lower surface of said one of said adjacent panels is broken along a first line adjacent said one panel overlapping edge, and said one panel overlapping edge is sealed along its conductivity broken first line to the underlying edge of the other of said adjacent panels.
