<p>A system for forming a textured surface on a geomembrane (12) includes support surface (20), a first set of rollers (14, 16) for passing the geomembrane, a heater (22) positioned in proximity to the desired surface of the geomembrane to heat the geomembrane to a desired temperature, and a particle distributor (26) positioned above the geomembrane to apply solid particles of desired size and geometry onto the surface of the geomembrane. A second set of rollers (40) is positioned adjacent to the surface to receive the particle-coated geomembrane after the particles have been distributed thereon. The heater includes a preheater (22) positioned on one side of the particle distributor and a postheater (24) positioned on an opposite side of the particle distributor. The preheater (22) serves to elevate a temperature of the surface of the geomembrane prior to receiving particle thereon, while the postheater serves to bond the distributed particles onto the surface of the geomembrane.</p> |
