A COMANCO project started last week in Parker Arizona. The project is a landfill expansion that includes installation of reinforced geosynthetic clay liner (GCL) and 60-mil high-density polyethylene (HDPE) double-sided textured geomembrane. The COMANCO team has worked safely through windy and dusty conditions at the start of the project. The project teams includes superintendent Martin Calderon, project engineer Chris Washa, and project manager Scott Harker.
