Abstract: A system for forming a textured surface on a geomembrane including a support surface, a first set of rollers for passing the geomembrane onto the support surface such that a surface of the geomembrane faces upwardly, a heater positioned in proximity to the surface of the geomembrane so as to heat the geomembrane to a desired elevated temperature, a particle distributer positioned above the geomembrane so as to pass solid particles onto the surface of the geomembrane in a desired particle distribution. The particles can have a desired size and geometry as they are passed onto the surface of the geomembrane. A second set of rollers is positioned adjacent to the port surface so as to receive the geomembrane after the particles have been distributed thereon. The heater includes a preheater positioned on one side of the particle distributor and a postheater positioned on an opposite side of the particle distributor.

Abstract: An apparatus for detecting a connection between adjacent vertical panels having a first contact element positioned adjacent a bottom of one of the panels, a second contact element positioned adjacent a bottom of an adjacent panel, a first conductive line extending from the first contact element, a second conductive line extending from the second contact element, an electrical source for passing a current to at least one of the first and second conductive lines, and a detector connected to one of the first and second conductive lines for ascertaining the existence of a connection between the first contact element and the second contact element. The second contact element is positioned in proximity to the first contact element when the panels are connected together. The first contact element is affixed to a connector member of the panel. The second contact element is affixed in a channel of an adjacent panel. The connector member is a T-shaped member.

Abstract: A roller machine and method for installing a flexible panel into a trench including a frame, a prime mover connected to the frame, and a plurality of rollers positioned on the frame. The plurality of rollers defining a curved path of travel for the panel. The path of travel has an entry and an exit. The path of travel is nearly vertical adjacent to the exit above and adjacent to the trench. The prime mover is drivingly connected to at least one of the plurality of rollers. The plurality of rollers includes a plurality of support rollers extending across the frame and having an adjustable length generally corresponding to a width dimension of the panel and a plurality of guide rollers arranged in aligned pairs. The guide rollers are positioned adjacent opposite ends of the support rollers and are arranged adjacent to the exit of the path of travel. The path of travel extends between each of the aligned pairs of guide rollers.
