COMANCO Environmental performed remediation work to an existing landfill closure cap in Harriman, TN. A 4,000 SF area of the cap needed to be enhanced to help withstand stormwater damage that has occurred in the past. Once this area was excavated down to sub-grade, a new double-sided geocomposite was deployed. A new gas vent pipe system was installed over the geocomposite followed by a layer of 80-mil gundseal (a geomembrane / GCL hybrid product). 18″ of protective cover soil topped with mulching and seeding was then placed to match the surrounding existing conditions.
Good job to Superintendent, Jorge Barrantes and crew to another safe and successful project completed.
