Coffin Butte Oregon Landfill Construction


Liner installation has begun at the Coffin Butte Landfill in Oregon. The installation includes a nine-layer installation on the slopes. These layers consist of: geotextile separator, tertiary 60-mil double-sided textured high density polyethylene (HDPE) liner, double-sided geocomposite, secondary 40-mil double-sided textured HDPE liner, geosynthetic clay liner (GCL), primary 60-mil double-sided textured HDPE liner, geotextile, single-sided geocomposite, and a rain tarp. This project is around 80% slope work which should be a demanding job for COMANCO. Tony Sanchez is the Superintendent, Scott Harker is the Project Manager, and Chris Washa is the Project Engineer on the project.
